+module ActionView #:nodoc:
+  # = Action View Base
+  #
+  # Action View templates can be written in several ways. If the template file has a <tt>.erb</tt> extension then it uses a mixture of ERB
+  # (included in Ruby) and HTML. If the template file has a <tt>.builder</tt> extension then Jim Weirich's Builder::XmlMarkup library is used.
+  #
+  # == ERB
+  #
+  # You trigger ERB by using embeddings such as <% %>, <% -%>, and <%= %>. The <%= %> tag set is used when you want output. Consider the
+  # following loop for names:
+  #
+  #   <b>Names of all the people</b>
+  #   <% @people.each do |person| %>
+  #     Name: <%= person.name %><br/>
+  #   <% end %>
+  #
+  # The loop is setup in regular embedding tags <% %> and the name is written using the output embedding tag <%= %>. Note that this
+  # is not just a usage suggestion. Regular output functions like print or puts won't work with ERB templates. So this would be wrong:
+  #
+  #   <%# WRONG %>
+  #   Hi, Mr. <% puts "Frodo" %>
+  #
+  # If you absolutely must write from within a function use +concat+.
+  #
+  # <%- and -%> suppress leading and trailing whitespace, including the trailing newline, and can be used interchangeably with <% and %>.
+  #
+  # === Using sub templates
+  #
+  # Using sub templates allows you to sidestep tedious replication and extract common display structures in shared templates. The
+  # classic example is the use of a header and footer (even though the Action Pack-way would be to use Layouts):
+  #
+  #   <%= render "shared/header" %>
+  #   Something really specific and terrific
+  #   <%= render "shared/footer" %>
+  #
+  # As you see, we use the output embeddings for the render methods. The render call itself will just return a string holding the
+  # result of the rendering. The output embedding writes it to the current template.
+  #
+  # But you don't have to restrict yourself to static includes. Templates can share variables amongst themselves by using instance
+  # variables defined using the regular embedding tags. Like this:
+  #
+  #   <% @page_title = "A Wonderful Hello" %>
+  #   <%= render "shared/header" %>
+  #
+  # Now the header can pick up on the <tt>@page_title</tt> variable and use it for outputting a title tag:
+  #
+  #   <title><%= @page_title %></title>
+  #
+  # === Passing local variables to sub templates
+  #
+  # You can pass local variables to sub templates by using a hash with the variable names as keys and the objects as values:
+  #
+  #   <%= render "shared/header", { headline: "Welcome", person: person } %>
+  #
+  # These can now be accessed in <tt>shared/header</tt> with:
+  #
+  #   Headline: <%= headline %>
+  #   First name: <%= person.first_name %>
+  #
+  # If you need to find out whether a certain local variable has been assigned a value in a particular render call,
+  # you need to use the following pattern:
+  #
+  #   <% if local_assigns.has_key? :headline %>
+  #     Headline: <%= headline %>
+  #   <% end %>
+  #
+  # Testing using <tt>defined? headline</tt> will not work. This is an implementation restriction.
+  #
+  # === Template caching
+  #
+  # By default, Rails will compile each template to a method in order to render it. When you alter a template,
+  # Rails will check the file's modification time and recompile it in development mode.
+  #
+  # == Builder
+  #
+  # Builder templates are a more programmatic alternative to ERB. They are especially useful for generating XML content. An XmlMarkup object
+  # named +xml+ is automatically made available to templates with a <tt>.builder</tt> extension.
+  #
+  # Here are some basic examples:
+  #
+  #   xml.em("emphasized")                                 # => <em>emphasized</em>
+  #   xml.em { xml.b("emph & bold") }                      # => <em><b>emph &amp; bold</b></em>
+  #   xml.a("A Link", "href" => "http://onestepback.org")  # => <a href="http://onestepback.org">A Link</a>
+  #   xml.target("name" => "compile", "option" => "fast")  # => <target option="fast" name="compile"\>
+  #                                                        # NOTE: order of attributes is not specified.
+  #
+  # Any method with a block will be treated as an XML markup tag with nested markup in the block. For example, the following:
+  #
+  #   xml.div do
+  #     xml.h1(@person.name)
+  #     xml.p(@person.bio)
+  #   end
+  #
+  # would produce something like:
+  #
+  #   <div>
+  #     <h1>David Heinemeier Hansson</h1>
+  #     <p>A product of Danish Design during the Winter of '79...</p>
+  #   </div>
+  #
+  # A full-length RSS example actually used on Basecamp:
+  #
+  #   xml.rss("version" => "2.0", "xmlns:dc" => "http://purl.org/dc/elements/1.1/") do
+  #     xml.channel do
+  #       xml.title(@feed_title)
+  #       xml.link(@url)
+  #       xml.description "Basecamp: Recent items"
+  #       xml.language "en-us"
+  #       xml.ttl "40"
+  #
+  #       @recent_items.each do |item|
+  #         xml.item do
+  #           xml.title(item_title(item))
+  #           xml.description(item_description(item)) if item_description(item)
+  #           xml.pubDate(item_pubDate(item))
+  #           xml.guid(@person.firm.account.url + @recent_items.url(item))
+  #           xml.link(@person.firm.account.url + @recent_items.url(item))
+  #
+  #           xml.tag!("dc:creator", item.author_name) if item_has_creator?(item)

+      #
+      # ==== Options
+      # You can add HTML attributes using the +options+. The +options+ supports
+      # two additional keys for convenience and conformance:
+      #
+      # * <tt>:poster</tt> - Set an image (like a screenshot) to be shown
+      #   before the video loads. The path is calculated like the +src+ of +image_tag+.
+      # * <tt>:size</tt> - Supplied as "{Width}x{Height}", so "30x45" becomes

+    #
+    # === Using asset hosts
+    #
+    # By default, Rails links to these assets on the current host in the public
+    # folder, but you can direct Rails to link to assets from a dedicated asset
+    # server by setting <tt>ActionController::Base.asset_host</tt> in the application
+    # configuration, typically in <tt>config/environments/production.rb</tt>.
+    # For example, you'd define <tt>assets.example.com</tt> to be your asset
+    # host this way, inside the <tt>configure</tt> block of your environment-specific
+    # configuration files or <tt>config/application.rb</tt>:
+    #
+    #   config.action_controller.asset_host = "assets.example.com"
+    #
+    # Helpers take that into account:
+    #
+    #   image_tag("rails.png")
+    #   # => <img alt="Rails" src="http://assets.example.com/assets/rails.png" />
+    #   stylesheet_link_tag("application")
+    #   # => <link href="http://assets.example.com/assets/application.css" media="screen" rel="stylesheet" />
+    #
+    # Browsers typically open at most two simultaneous connections to a single
+    # host, which means your assets often have to wait for other assets to finish
+    # downloading. You can alleviate this by using a <tt>%d</tt> wildcard in the
+    # +asset_host+. For example, "assets%d.example.com". If that wildcard is
+    # present Rails distributes asset requests among the corresponding four hosts
+    # "assets0.example.com", ..., "assets3.example.com". With this trick browsers
+    # will open eight simultaneous connections rather than two.

+    #   # => <link href="http://assets2.example.com/assets/application.css" media="screen" rel="stylesheet" />
+    #
+    # To do this, you can either setup four actual hosts, or you can use wildcard
+    # DNS to CNAME the wildcard to a single asset host. You can read more about
+    # setting up your DNS CNAME records from your ISP.
+    #
+    # Note: This is purely a browser performance optimization and is not meant
+    # for server load balancing. See http://www.die.net/musings/page_load_time/
+    # for background.
+    #
+    # Alternatively, you can exert more control over the asset host by setting
+    # +asset_host+ to a proc like this:
+    #
+    #   ActionController::Base.asset_host = Proc.new { |source|
+    #     "http://assets#{Digest::MD5.hexdigest(source).to_i(16) % 2 + 1}.example.com"
+    #   }
+    #   image_tag("rails.png")
+    #   # => <img alt="Rails" src="http://assets1.example.com/assets/rails.png" />
+    #   stylesheet_link_tag("application")
+    #   # => <link href="http://assets2.example.com/assets/application.css" media="screen" rel="stylesheet" />
+    #
+    # The example above generates "http://assets1.example.com" and
+    # "http://assets2.example.com". This option is useful for example if
+    # you need fewer/more than four hosts, custom host names, etc.
+    #
+    # As you see the proc takes a +source+ parameter. That's a string with the
+    # absolute path of the asset, for example "/assets/rails.png".
+    #
+    #    ActionController::Base.asset_host = Proc.new { |source|
+    #      if source.ends_with?('.css')
+    #        "http://stylesheets.example.com"
+    #      else
+    #        "http://assets.example.com"
+    #      end
+    #    }
+    #   image_tag("rails.png")
+    #   # => <img alt="Rails" src="http://assets.example.com/assets/rails.png" />
+    #   stylesheet_link_tag("application")
+    #   # => <link href="http://stylesheets.example.com/assets/application.css" media="screen" rel="stylesheet" />
+    #
+    # Alternatively you may ask for a second parameter +request+. That one is
+    # particularly useful for serving assets from an SSL-protected page. The
+    # example proc below disables asset hosting for HTTPS connections, while
+    # still sending assets for plain HTTP requests from asset hosts. If you don't
+    # have SSL certificates for each of the asset hosts this technique allows you
+    # to avoid warnings in the client about mixed media.

+    #       "#{request.protocol}assets.example.com"
+    #     end
+    #   }

+module ActionView
+  # = Action View Cache Helper
+  module Helpers
+    module CacheHelper
+      # This helper exposes a method for caching fragments of a view
+      # rather than an entire action or page. This technique is useful
+      # caching pieces like menus, lists of newstopics, static HTML
+      # fragments, and so on. This method takes a block that contains
+      # the content you wish to cache.
+      #
+      # The best way to use this is by doing key-based cache expiration
+      # on top of a cache store like Memcached that'll automatically
+      # kick out old entries. For more on key-based expiration, see:
+      # http://37signals.com/svn/posts/3113-how-key-based-cache-expiration-works
+      #
+      # When using this method, you list the cache dependency as the name of the cache, like so:
+      #
+      #   <% cache project do %>
+      #     <b>All the topics on this project</b>
+      #     <%= render project.topics %>
+      #   <% end %>
+      #
+      # This approach will assume that when a new topic is added, you'll touch
+      # the project. The cache key generated from this call will be something like:
+      #
+      #   views/projects/123-20120806214154/7a1156131a6928cb0026877f8b749ac9
+      #         ^class   ^id ^updated_at    ^template tree digest
+      #
+      # The cache is thus automatically bumped whenever the project updated_at is touched.
+      #
+      # If your template cache depends on multiple sources (try to avoid this to keep things simple),
+      # you can name all these dependencies as part of an array:
+      #
+      #   <% cache [ project, current_user ] do %>
+      #     <b>All the topics on this project</b>
+      #     <%= render project.topics %>
+      #   <% end %>
+      #
+      # This will include both records as part of the cache key and updating either of them will
+      # expire the cache.
+      #
+      # ==== Template digest
+      #
+      # The template digest that's added to the cache key is computed by taking an md5 of the
+      # contents of the entire template file. This ensures that your caches will automatically
+      # expire when you change the template file.
+      #
+      # Note that the md5 is taken of the entire template file, not just what's within the
+      # cache do/end call. So it's possible that changing something outside of that call will
+      # still expire the cache.
+      #
+      # Additionally, the digestor will automatically look through your template file for
+      # explicit and implicit dependencies, and include those as part of the digest.
+      #
+      # The digestor can be bypassed by passing skip_digest: true as an option to the cache call:
+      #
+      #   <% cache project, skip_digest: true do %>
+      #     <b>All the topics on this project</b>
+      #     <%= render project.topics %>
+      #   <% end %>
+      #
+      # ==== Implicit dependencies
+      #
+      # Most template dependencies can be derived from calls to render in the template itself.
+      # Here are some examples of render calls that Cache Digests knows how to decode:
+      #
+      #   render partial: "comments/comment", collection: commentable.comments
+      #   render "comments/comments"
+      #   render 'comments/comments'
+      #   render('comments/comments')
+      #
+      #   render "header" => render("comments/header")
+      #
+      #   render(@topic)         => render("topics/topic")
+      #   render(topics)         => render("topics/topic")
+      #   render(message.topics) => render("topics/topic")
+      #
+      # It's not possible to derive all render calls like that, though. Here are a few examples of things that can't be derived:
+      #
+      #   render group_of_attachments
+      #   render @project.documents.where(published: true).order('created_at')
+      #
+      # You will have to rewrite those to the explicit form:
+      #
+      #   render partial: 'attachments/attachment', collection: group_of_attachments
+      #   render partial: 'documents/document', collection: @project.documents.where(published: true).order('created_at')
+      #
+      # === Explicit dependencies
+      #
+      # Some times you'll have template dependencies that can't be derived at all. This is typically
+      # the case when you have template rendering that happens in helpers. Here's an example:
+      #
+      #   <%= render_sortable_todolists @project.todolists %>
+      #
+      # You'll need to use a special comment format to call those out:
+      #
+      #   <%# Template Dependency: todolists/todolist %>
+      #   <%= render_sortable_todolists @project.todolists %>
+      #
+      # The pattern used to match these is /# Template Dependency: ([^ ]+)/, so it's important that you type it out just so.
+      # You can only declare one template dependency per line.
+      #
+      # === External dependencies
+      #
+      # If you use a helper method, for example, inside of a cached block and you then update that helper,
+      # you'll have to bump the cache as well. It doesn't really matter how you do it, but the md5 of the template file
+      # must change. One recommendation is to simply be explicit in a comment, like:
+      #
+      #   <%# Helper Dependency Updated: May 6, 2012 at 6pm %>
+      #   <%= some_helper_method(person) %>
+      #
+      # Now all you'll have to do is change that timestamp when the helper method changes.

+      # <tt>yield</tt> in a layout. For example:
+      #
+      #   <%# This is the layout %>
+      #   <html xmlns="http://www.w3.org/1999/xhtml" xml:lang="en" lang="en">
+      #   <head>
+      #     <title>My Website</title>
+      #     <%= yield :script %>
+      #   </head>
+      #   <body>
+      #     <%= yield %>
+      #   </body>
+      #   </html>
+      #
+      # And now, we'll create a view that has a <tt>content_for</tt> call that
+      # creates the <tt>script</tt> identifier.
+      #
+      #   <%# This is our view %>
+      #   Please login!
+      #
+      #   <% content_for :script do %>
+      #     <script>alert('You are not authorized to view this page!')</script>
+      #   <% end %>
+      #
+      # Then, in another view, you could to do something like this:
+      #
+      #   <%= link_to 'Logout', action: 'logout', remote: true %>
+      #
+      #   <% content_for :script do %>
+      #     <%= javascript_include_tag :defaults %>
+      #   <% end %>
+      #
+      # That will place +script+ tags for your default set of JavaScript files on the page;
+      # this technique is useful if you'll only be using these scripts in a few views.
+      #
+      # Note that content_for concatenates (default) the blocks it is given for a particular
+      # identifier in order. For example:
+      #
+      #   <% content_for :navigation do %>
+      #     <li><%= link_to 'Home', action: 'index' %></li>
+      #   <% end %>
+      #
+      #  And in other place:
+      #
+      #   <% content_for :navigation do %>
+      #     <li><%= link_to 'Login', action: 'login' %></li>
+      #   <% end %>
+      #
+      # Then, in another template or layout, this code would render both links in order:
+      #
+      #   <ul><%= content_for :navigation %></ul>
+      #
+      # If the flush parameter is true content_for replaces the blocks it is given. For example:
+      #
+      #   <% content_for :navigation do %>
+      #     <li><%= link_to 'Home', action: 'index' %></li>
+      #   <% end %>
+      #
+      #   <%#  Add some other content, or use a different template: %>
+      #
+      #   <% content_for :navigation, flush: true do %>
+      #     <li><%= link_to 'Login', action: 'login' %></li>
+      #   <% end %>
+      #
+      # Then, in another template or layout, this code would render only the last link:
+      #
+      #   <ul><%= content_for :navigation %></ul>
+      #
+      # Lastly, simple content can be passed as a parameter:
+      #
+      #   <% content_for :script, javascript_include_tag(:defaults) %>
+      #
+      # WARNING: content_for is ignored in caches. So you shouldn't use it for elements that will be fragment cached.

+    #
+    # * <tt>:prefix</tt> - overwrites the default prefix of "date" used for the select names. So specifying "birthday"
+    #   would give \birthday[month] instead of \date[month] if passed to the <tt>select_month</tt> method.
+    # * <tt>:include_blank</tt> - set to true if it should be possible to set an empty date.
+    # * <tt>:discard_type</tt> - set to true if you want to discard the type part of the select name. If set to true,
+    #   the <tt>select_month</tt> method would use simply "date" (which can be overwritten using <tt>:prefix</tt>) instead
+    #   of \date[month].

+      #
+      # ==== Options
+      # * <tt>:use_month_numbers</tt> - Set to true if you want to use month numbers rather than month names (e.g.
+      #   "2" instead of "February").
+      # * <tt>:use_two_digit_numbers</tt> - Set to true if you want to display two digit month and day numbers (e.g.
+      #   "02" instead of "February" and "08" instead of "8").
+      # * <tt>:use_short_month</tt>   - Set to true if you want to use abbreviated month names instead of full
+      #   month names (e.g. "Feb" instead of "February").
+      # * <tt>:add_month_numbers</tt>  - Set to true if you want to use both month numbers and month names (e.g.
+      #   "2 - February" instead of "February").
+      # * <tt>:use_month_names</tt>   - Set to an array with 12 month names if you want to customize month names.
+      #   Note: You can also use Rails' i18n functionality for this.
+      # * <tt>:date_separator</tt>    - Specifies a string to separate the date fields. Default is "" (i.e. nothing).
+      # * <tt>:start_year</tt>        - Set the start year for the year select. Default is <tt>Time.now.year - 5</tt>.
+      # * <tt>:end_year</tt>          - Set the end year for the year select. Default is <tt>Time.now.year + 5</tt>.
+      # * <tt>:discard_day</tt>       - Set to true if you don't want to show a day select. This includes the day
+      #   as a hidden field instead of showing a select field. Also note that this implicitly sets the day to be the
+      #   first of the given month in order to not create invalid dates like 31 February.
+      # * <tt>:discard_month</tt>     - Set to true if you don't want to show a month select. This includes the month
+      #   as a hidden field instead of showing a select field. Also note that this implicitly sets :discard_day to true.
+      # * <tt>:discard_year</tt>      - Set to true if you don't want to show a year select. This includes the year
+      #   as a hidden field instead of showing a select field.
+      # * <tt>:order</tt>             - Set to an array containing <tt>:day</tt>, <tt>:month</tt> and <tt>:year</tt> to
+      #   customize the order in which the select fields are shown. If you leave out any of the symbols, the respective
+      #   select will not be shown (like when you set <tt>discard_xxx: true</tt>. Defaults to the order defined in
+      #   the respective locale (e.g. [:year, :month, :day] in the en locale that ships with Rails).
+      # * <tt>:include_blank</tt>     - Include a blank option in every select field so it's possible to set empty
+      #   dates.
+      # * <tt>:default</tt>           - Set a default date if the affected date isn't set or is nil.
+      # * <tt>:selected</tt>          - Set a date that overrides the actual value.
+      # * <tt>:disabled</tt>          - Set to true if you want show the select fields as disabled.
+      # * <tt>:prompt</tt>            - Set to true (for a generic prompt), a prompt string or a hash of prompt strings
+      #   for <tt>:year</tt>, <tt>:month</tt>, <tt>:day</tt>, <tt>:hour</tt>, <tt>:minute</tt> and <tt>:second</tt>.
+      #   Setting this option prepends a select option with a generic prompt  (Day, Month, Year, Hour, Minute, Seconds)
+      #   or the given prompt string.
+      # * <tt>:with_css_classes</tt>   - Set to true if you want assign different styles for 'select' tags. This option
+      #   automatically set classes 'year', 'month', 'day', 'hour', 'minute' and 'second' for your 'select' tags.
+      #

+module ActionView
+  # = Action View Form Helpers
+  module Helpers
+    # Form helpers are designed to make working with resources much easier
+    # compared to using vanilla HTML.
+    #
+    # Typically, a form designed to create or update a resource reflects the
+    # identity of the resource in several ways: (i) the url that the form is
+    # sent to (the form element's +action+ attribute) should result in a request
+    # being routed to the appropriate controller action (with the appropriate <tt>:id</tt>
+    # parameter in the case of an existing resource), (ii) input fields should
+    # be named in such a way that in the controller their values appear in the
+    # appropriate places within the +params+ hash, and (iii) for an existing record,
+    # when the form is initially displayed, input fields corresponding to attributes
+    # of the resource should show the current values of those attributes.
+    #
+    # In Rails, this is usually achieved by creating the form using +form_for+ and
+    # a number of related helper methods. +form_for+ generates an appropriate <tt>form</tt>
+    # tag and yields a form builder object that knows the model the form is about.
+    # Input fields are created by calling methods defined on the form builder, which
+    # means they are able to generate the appropriate names and default values
+    # corresponding to the model attributes, as well as convenient IDs, etc.
+    # Conventions in the generated field names allow controllers to receive form data
+    # nicely structured in +params+ with no effort on your side.
+    #
+    # For example, to create a new person you typically set up a new instance of
+    # +Person+ in the <tt>PeopleController#new</tt> action, <tt>@person</tt>, and
+    # in the view template pass that object to +form_for+:
+    #
+    #   <%= form_for @person do |f| %>
+    #     <%= f.label :first_name %>:
+    #     <%= f.text_field :first_name %><br />
+    #
+    #     <%= f.label :last_name %>:
+    #     <%= f.text_field :last_name %><br />
+    #
+    #     <%= f.submit %>
+    #   <% end %>
+    #
+    # The HTML generated for this would be (modulus formatting):
+    #
+    #   <form action="/people" class="new_person" id="new_person" method="post">
+    #     <div style="margin:0;padding:0;display:inline">
+    #       <input name="authenticity_token" type="hidden" value="NrOp5bsjoLRuK8IW5+dQEYjKGUJDe7TQoZVvq95Wteg=" />
+    #     </div>
+    #     <label for="person_first_name">First name</label>:
+    #     <input id="person_first_name" name="person[first_name]" type="text" /><br />
+    #
+    #     <label for="person_last_name">Last name</label>:
+    #     <input id="person_last_name" name="person[last_name]" type="text" /><br />
+    #
+    #     <input name="commit" type="submit" value="Create Person" />
+    #   </form>
+    #
+    # As you see, the HTML reflects knowledge about the resource in several spots,
+    # like the path the form should be submitted to, or the names of the input fields.
+    #
+    # In particular, thanks to the conventions followed in the generated field names, the
+    # controller gets a nested hash <tt>params[:person]</tt> with the person attributes
+    # set in the form. That hash is ready to be passed to <tt>Person.create</tt>:
+    #
+    #   if @person = Person.create(params[:person])
+    #     # success
+    #   else
+    #     # error handling
+    #   end
+    #
+    # Interestingly, the exact same view code in the previous example can be used to edit
+    # a person. If <tt>@person</tt> is an existing record with name "John Smith" and ID 256,
+    # the code above as is would yield instead:
+    #
+    #   <form action="/people/256" class="edit_person" id="edit_person_256" method="post">
+    #     <div style="margin:0;padding:0;display:inline">
+    #       <input name="_method" type="hidden" value="patch" />
+    #       <input name="authenticity_token" type="hidden" value="NrOp5bsjoLRuK8IW5+dQEYjKGUJDe7TQoZVvq95Wteg=" />
+    #     </div>
+    #     <label for="person_first_name">First name</label>:
+    #     <input id="person_first_name" name="person[first_name]" type="text" value="John" /><br />
+    #
+    #     <label for="person_last_name">Last name</label>:
+    #     <input id="person_last_name" name="person[last_name]" type="text" value="Smith" /><br />
+    #
+    #     <input name="commit" type="submit" value="Update Person" />
+    #   </form>
+    #
+    # Note that the endpoint, default values, and submit button label are tailored for <tt>@person</tt>.
+    # That works that way because the involved helpers know whether the resource is a new record or not,
+    # and generate HTML accordingly.
+    #
+    # The controller would receive the form data again in <tt>params[:person]</tt>, ready to be
+    # passed to <tt>Person#update</tt>:
+    #
+    #   if @person.update(params[:person])
+    #     # success
+    #   else
+    #     # error handling
+    #   end
+    #
+    # That's how you typically work with resources.

+
+      # Creates a form that allows the user to create or update the attributes
+      # of a specific model object.
+      #
+      # The method can be used in several slightly different ways, depending on
+      # how much you wish to rely on Rails to infer automatically from the model
+      # how the form should be constructed. For a generic model object, a form
+      # can be created by passing +form_for+ a string or symbol representing
+      # the object we are concerned with:
+      #
+      #   <%= form_for :person do |f| %>
+      #     First name: <%= f.text_field :first_name %><br />
+      #     Last name : <%= f.text_field :last_name %><br />
+      #     Biography : <%= f.text_area :biography %><br />
+      #     Admin?    : <%= f.check_box :admin %><br />
+      #     <%= f.submit %>
+      #   <% end %>
+      #
+      # The variable +f+ yielded to the block is a FormBuilder object that
+      # incorporates the knowledge about the model object represented by
+      # <tt>:person</tt> passed to +form_for+. Methods defined on the FormBuilder
+      # are used to generate fields bound to this model. Thus, for example,
+      #
+      #   <%= f.text_field :first_name %>
+      #
+      # will get expanded to
+      #
+      #   <%= text_field :person, :first_name %>
+      # which results in an html <tt><input></tt> tag whose +name+ attribute is
+      # <tt>person[first_name]</tt>. This means that when the form is submitted,
+      # the value entered by the user will be available in the controller as
+      # <tt>params[:person][:first_name]</tt>.
+      #
+      # For fields generated in this way using the FormBuilder,
+      # if <tt>:person</tt> also happens to be the name of an instance variable
+      # <tt>@person</tt>, the default value of the field shown when the form is
+      # initially displayed (e.g. in the situation where you are editing an
+      # existing record) will be the value of the corresponding attribute of
+      # <tt>@person</tt>.
+      #
+      # The rightmost argument to +form_for+ is an
+      # optional hash of options -
+      #
+      # * <tt>:url</tt> - The URL the form is to be submitted to. This may be
+      #   represented in the same way as values passed to +url_for+ or +link_to+.
+      #   So for example you may use a named route directly. When the model is
+      #   represented by a string or symbol, as in the example above, if the
+      #   <tt>:url</tt> option is not specified, by default the form will be
+      #   sent back to the current url (We will describe below an alternative
+      #   resource-oriented usage of +form_for+ in which the URL does not need
+      #   to be specified explicitly).
+      # * <tt>:namespace</tt> - A namespace for your form to ensure uniqueness of
+      #   id attributes on form elements. The namespace attribute will be prefixed
+      #   with underscore on the generated HTML id.
+      # * <tt>:html</tt> - Optional HTML attributes for the form tag.
+      #
+      # Also note that +form_for+ doesn't create an exclusive scope. It's still
+      # possible to use both the stand-alone FormHelper methods and methods
+      # from FormTagHelper. For example:
+      #
+      #   <%= form_for :person do |f| %>
+      #     First name: <%= f.text_field :first_name %>
+      #     Last name : <%= f.text_field :last_name %>
+      #     Biography : <%= text_area :person, :biography %>
+      #     Admin?    : <%= check_box_tag "person[admin]", "1", @person.company.admin? %>
+      #     <%= f.submit %>
+      #   <% end %>
+      #
+      # This also works for the methods in FormOptionHelper and DateHelper that
+      # are designed to work with an object as base, like
+      # FormOptionHelper#collection_select and DateHelper#datetime_select.
+      #
+      # === #form_for with a model object
+      #
+      # In the examples above, the object to be created or edited was
+      # represented by a symbol passed to +form_for+, and we noted that
+      # a string can also be used equivalently. It is also possible, however,
+      # to pass a model object itself to +form_for+. For example, if <tt>@post</tt>
+      # is an existing record you wish to edit, you can create the form using
+      #
+      #   <%= form_for @post do |f| %>
+      #     ...
+      #   <% end %>
+      #
+      # This behaves in almost the same way as outlined previously, with a
+      # couple of small exceptions. First, the prefix used to name the input
+      # elements within the form (hence the key that denotes them in the +params+
+      # hash) is actually derived from the object's _class_, e.g. <tt>params[:post]</tt>
+      # if the object's class is +Post+. However, this can be overwritten using
+      # the <tt>:as</tt> option, e.g. -
+      #
+      #   <%= form_for(@person, as: :client) do |f| %>
+      #     ...
+      #   <% end %>
+      #
+      # would result in <tt>params[:client]</tt>.
+      #
+      # Secondly, the field values shown when the form is initially displayed
+      # are taken from the attributes of the object passed to +form_for+,
+      # regardless of whether the object is an instance
+      # variable. So, for example, if we had a _local_ variable +post+
+      # representing an existing record,
+      #
+      #   <%= form_for post do |f| %>
+      #     ...
+      #   <% end %>
+      #
+      # would produce a form with fields whose initial state reflect the current
+      # values of the attributes of +post+.
+      #
+      # === Resource-oriented style
+      #
+      # In the examples just shown, although not indicated explicitly, we still
+      # need to use the <tt>:url</tt> option in order to specify where the
+      # form is going to be sent. However, further simplification is possible
+      # if the record passed to +form_for+ is a _resource_, i.e. it corresponds
+      # to a set of RESTful routes, e.g. defined using the +resources+ method
+      # in <tt>config/routes.rb</tt>. In this case Rails will simply infer the
+      # appropriate URL from the record itself. For example,
+      #
+      #   <%= form_for @post do |f| %>
+      #     ...
+      #   <% end %>
+      #
+      # is then equivalent to something like:
+      #
+      #   <%= form_for @post, as: :post, url: post_path(@post), method: :patch, html: { class: "edit_post", id: "edit_post_45" } do |f| %>
+      #     ...
+      #   <% end %>
+      #
+      # And for a new record
+      #
+      #   <%= form_for(Post.new) do |f| %>
+      #     ...
+      #   <% end %>
+      #
+      # is equivalent to something like:
+      #
+      #   <%= form_for @post, as: :post, url: posts_path, html: { class: "new_post", id: "new_post" } do |f| %>
+      #     ...
+      #   <% end %>
+      #
+      # However you can still overwrite individual conventions, such as:
+      #
+      #   <%= form_for(@post, url: super_posts_path) do |f| %>
+      #     ...
+      #   <% end %>
+      #
+      # You can also set the answer format, like this:
+      #
+      #   <%= form_for(@post, format: :json) do |f| %>
+      #     ...
+      #   <% end %>
+      #
+      # For namespaced routes, like +admin_post_url+:
+      #
+      #   <%= form_for([:admin, @post]) do |f| %>
+      #    ...
+      #   <% end %>
+      #
+      # If your resource has associations defined, for example, you want to add comments
+      # to the document given that the routes are set correctly:
+      #
+      #   <%= form_for([@document, @comment]) do |f| %>
+      #    ...
+      #   <% end %>
+      #
+      # Where <tt>@document = Document.find(params[:id])</tt> and
+      # <tt>@comment = Comment.new</tt>.
+      #
+      # === Setting the method
+      #
+      # You can force the form to use the full array of HTTP verbs by setting
+      #
+      #    method: (:get|:post|:patch|:put|:delete)
+      #
+      # in the options hash. If the verb is not GET or POST, which are natively
+      # supported by HTML forms, the form will be set to POST and a hidden input
+      # called _method will carry the intended verb for the server to interpret.
+      #
+      # === Unobtrusive JavaScript
+      #
+      # Specifying:
+      #
+      #    remote: true
+      #
+      # in the options hash creates a form that will allow the unobtrusive JavaScript drivers to modify its
+      # behavior. The expected default behavior is an XMLHttpRequest in the background instead of the regular
+      # POST arrangement, but ultimately the behavior is the choice of the JavaScript driver implementor.
+      # Even though it's using JavaScript to serialize the form elements, the form submission will work just like
+      # a regular submission as viewed by the receiving side (all elements available in <tt>params</tt>).
+      #
+      # Example:
+      #
+      #   <%= form_for(@post, remote: true) do |f| %>
+      #     ...
+      #   <% end %>
+      #
+      # The HTML generated for this would be:
+      #
+      #   <form action='http://www.example.com' method='post' data-remote='true'>
+      #     <div style='margin:0;padding:0;display:inline'>
+      #       <input name='_method' type='hidden' value='patch' />
+      #     </div>
+      #     ...
+      #   </form>
+      #
+      # === Setting HTML options
+      #
+      # You can set data attributes directly by passing in a data hash, but all other HTML options must be wrapped in
+      # the HTML key. Example:
+      #
+      #   <%= form_for(@post, data: { behavior: "autosave" }, html: { name: "go" }) do |f| %>
+      #     ...
+      #   <% end %>
+      #
+      # The HTML generated for this would be:
+      #
+      #   <form action='http://www.example.com' method='post' data-behavior='autosave' name='go'>
+      #     <div style='margin:0;padding:0;display:inline'>
+      #       <input name='_method' type='hidden' value='patch' />
+      #     </div>
+      #     ...
+      #   </form>
+      #
+      # === Removing hidden model id's
+      #
+      # The form_for method automatically includes the model id as a hidden field in the form.
+      # This is used to maintain the correlation between the form data and its associated model.
+      # Some ORM systems do not use IDs on nested models so in this case you want to be able
+      # to disable the hidden id.
+      #
+      # In the following example the Post model has many Comments stored within it in a NoSQL database,
+      # thus there is no primary key for comments.
+      #
+      # Example:
+      #
+      #   <%= form_for(@post) do |f| %>
+      #     <%= f.fields_for(:comments, include_id: false) do |cf| %>
+      #       ...
+      #     <% end %>
+      #   <% end %>
+      #
+      # === Customized form builders
+      #
+      # You can also build forms using a customized FormBuilder class. Subclass
+      # FormBuilder and override or define some more helpers, then use your
+      # custom builder. For example, let's say you made a helper to
+      # automatically add labels to form inputs.
+      #
+      #   <%= form_for @person, url: { action: "create" }, builder: LabellingFormBuilder do |f| %>
+      #     <%= f.text_field :first_name %>
+      #     <%= f.text_field :last_name %>
+      #     <%= f.text_area :biography %>
+      #     <%= f.check_box :admin %>
+      #     <%= f.submit %>
+      #   <% end %>
+      #
+      # In this case, if you use this:
+      #
+      #   <%= render f %>
+      #
+      # The rendered template is <tt>people/_labelling_form</tt> and the local
+      # variable referencing the form builder is called
+      # <tt>labelling_form</tt>.
+      #
+      # The custom FormBuilder class is automatically merged with the options
+      # of a nested fields_for call, unless it's explicitly set.
+      #
+      # In many cases you will want to wrap the above in another helper, so you
+      # could do something like the following:
+      #
+      #   def labelled_form_for(record_or_name_or_array, *args, &block)
+      #     options = args.extract_options!
+      #     form_for(record_or_name_or_array, *(args << options.merge(builder: LabellingFormBuilder)), &block)
+      #   end
+      #
+      # If you don't need to attach a form to a model instance, then check out
+      # FormTagHelper#form_tag.
+      #
+      # === Form to external resources
+      #
+      # When you build forms to external resources sometimes you need to set an authenticity token or just render a form
+      # without it, for example when you submit data to a payment gateway number and types of fields could be limited.
+      #
+      # To set an authenticity token you need to pass an <tt>:authenticity_token</tt> parameter
+      #
+      #   <%= form_for @invoice, url: external_url, authenticity_token: 'external_token' do |f|
+      #     ...
+      #   <% end %>
+      #
+      # If you don't want to an authenticity token field be rendered at all just pass <tt>false</tt>:
+      #
+      #   <%= form_for @invoice, url: external_url, authenticity_token: false do |f|
+      #     ...
+      #   <% end %>
+      def form_for(record, options = {}, &block)
+        raise ArgumentError, "Missing block" unless block_given?
+        html_options = options[:html] ||= {}
+
+        case record
+        when String, Symbol

+          apply_form_for_options!(record, object, options)
+        end
+
+        html_options[:data]   = options.delete(:data)   if options.has_key?(:data)
+        html_options[:remote] = options.delete(:remote) if options.has_key?(:remote)

+      # Creates a scope around a specific model object like form_for, but
+      # doesn't create the form tags themselves. This makes fields_for suitable
+      # for specifying additional model objects in the same form.
+      #
+      # Although the usage and purpose of +field_for+ is similar to +form_for+'s,
+      # its method signature is slightly different. Like +form_for+, it yields
+      # a FormBuilder object associated with a particular model object to a block,
+      # and within the block allows methods to be called on the builder to
+      # generate fields associated with the model object. Fields may reflect
+      # a model object in two ways - how they are named (hence how submitted
+      # values appear within the +params+ hash in the controller) and what
+      # default values are shown when the form the fields appear in is first
+      # displayed. In order for both of these features to be specified independently,
+      # both an object name (represented by either a symbol or string) and the
+      # object itself can be passed to the method separately -
+      #
+      #   <%= form_for @person do |person_form| %>
+      #     First name: <%= person_form.text_field :first_name %>
+      #     Last name : <%= person_form.text_field :last_name %>
+      #
+      #     <%= fields_for :permission, @person.permission do |permission_fields| %>
+      #       Admin?  : <%= permission_fields.check_box :admin %>
+      #     <% end %>
+      #
+      #     <%= f.submit %>
+      #   <% end %>
+      #
+      # In this case, the checkbox field will be represented by an HTML +input+
+      # tag with the +name+ attribute <tt>permission[admin]</tt>, and the submitted
+      # value will appear in the controller as <tt>params[:permission][:admin]</tt>.
+      # If <tt>@person.permission</tt> is an existing record with an attribute
+      # +admin+, the initial state of the checkbox when first displayed will
+      # reflect the value of <tt>@person.permission.admin</tt>.
+      #
+      # Often this can be simplified by passing just the name of the model
+      # object to +fields_for+ -
+      #
+      #   <%= fields_for :permission do |permission_fields| %>
+      #     Admin?: <%= permission_fields.check_box :admin %>
+      #   <% end %>
+      #
+      # ...in which case, if <tt>:permission</tt> also happens to be the name of an
+      # instance variable <tt>@permission</tt>, the initial state of the input
+      # field will reflect the value of that variable's attribute <tt>@permission.admin</tt>.
+      #
+      # Alternatively, you can pass just the model object itself (if the first
+      # argument isn't a string or symbol +fields_for+ will realize that the
+      # name has been omitted) -
+      #
+      #   <%= fields_for @person.permission do |permission_fields| %>
+      #     Admin?: <%= permission_fields.check_box :admin %>
+      #   <% end %>
+      #
+      # and +fields_for+ will derive the required name of the field from the
+      # _class_ of the model object, e.g. if <tt>@person.permission</tt>, is
+      # of class +Permission+, the field will still be named <tt>permission[admin]</tt>.
+      #
+      # Note: This also works for the methods in FormOptionHelper and
+      # DateHelper that are designed to work with an object as base, like
+      # FormOptionHelper#collection_select and DateHelper#datetime_select.
+      #
+      # === Nested Attributes Examples
+      #
+      # When the object belonging to the current scope has a nested attribute
+      # writer for a certain attribute, fields_for will yield a new scope
+      # for that attribute. This allows you to create forms that set or change
+      # the attributes of a parent object and its associations in one go.
+      #
+      # Nested attribute writers are normal setter methods named after an
+      # association. The most common way of defining these writers is either
+      # with +accepts_nested_attributes_for+ in a model definition or by
+      # defining a method with the proper name. For example: the attribute
+      # writer for the association <tt>:address</tt> is called
+      # <tt>address_attributes=</tt>.
+      #
+      # Whether a one-to-one or one-to-many style form builder will be yielded
+      # depends on whether the normal reader method returns a _single_ object
+      # or an _array_ of objects.
+      #
+      # ==== One-to-one
+      #
+      # Consider a Person class which returns a _single_ Address from the
+      # <tt>address</tt> reader method and responds to the
+      # <tt>address_attributes=</tt> writer method:
+      #
+      #   class Person
+      #     def address
+      #       @address

+      # while the default +unchecked_value+ is set to 0 which is convenient for boolean values.
+      #
+      # ==== Gotcha
+      #
+      # The HTML specification says unchecked check boxes are not successful, and
+      # thus web browsers do not send them. Unfortunately this introduces a gotcha:
+      # if an +Invoice+ model has a +paid+ flag, and in the form that edits a paid
+      # invoice the user unchecks its check box, no +paid+ parameter is sent. So,
+      # any mass-assignment idiom like
+      #
+      #   @invoice.update(params[:invoice])
+      #
+      # wouldn't update the flag.
+      #
+      # To prevent this the helper generates an auxiliary hidden field before
+      # the very check box. The hidden field has the same name and its
+      # attributes mimic an unchecked check box.
+      #
+      # This way, the client either sends only the hidden field (representing
+      # the check box is unchecked), or both fields. Since the HTML specification
+      # says key/value pairs have to be sent in the same order they appear in the
+      # form, and parameters extraction gets the last occurrence of any repeated
+      # key in the query string, that works for ordinary forms.
+      #
+      # Unfortunately that workaround does not work when the check box goes
+      # within an array-like parameter, as in
+      #
+      #   <%= fields_for "project[invoice_attributes][]", invoice, index: nil do |form| %>
+      #     <%= form.check_box :paid %>
+      #     ...
+      #   <% end %>
+      #
+      # because parameter name repetition is precisely what Rails seeks to distinguish
+      # the elements of the array. For each item with a checked check box you
+      # get an extra ghost item with only that attribute, assigned to "0".
+      #
+      # In that case it is preferable to either use +check_box_tag+ or to use
+      # hashes instead of arrays.
+      #
+      #   # Let's say that @post.validated? is 1:
+      #   check_box("post", "validated")
+      #   # => <input name="post[validated]" type="hidden" value="0" />
+      #   #    <input checked="checked" type="checkbox" id="post_validated" name="post[validated]" value="1" />
+      #

+    # A +FormBuilder+ object is associated with a particular model object and

+    #     Name: <%= person_form.text_field :name %>
+    #     Admin: <%= person_form.check_box :admin %>
+    #   <% end %>
+    #
+    # In the above block, the a +FormBuilder+ object is yielded as the
+    # +person_form+ variable. This allows you to generate the +text_field+
+    # and +check_box+ fields by specifying their eponymous methods, which
+    # modify the underlying template and associates the +@person+ model object
+    # with the form.
+    #
+    # The +FormBuilder+ object can be thought of as serving as a proxy for the
+    # methods in the +FormHelper+ module. This class, however, allows you to
+    # call methods with the model object you are building the form for.
+    #
+    # You can create your own custom FormBuilder templates by subclasses this
+    # class. For example:
+    #
+    #   class MyFormBuilder < ActionView::Helpers::FormBuilder
+    #     def div_radio_button(method, tag_value, options = {})
+    #       @template.content_tag(:div,
+    #         @template.radio_button(
+    #           @object_name, method, tag_value, objectify_options(options)
+    #         )
+    #       )
+    #     end
+    #
+    # The above code creates a new method +div_radio_button+ which wraps a div
+    # around the a new radio button. Note that when options are passed in, you
+    # must called +objectify_options+ in order for the model object to get
+    # correctly passed to the method. If +objectify_options+ is not called,
+    # then the newly created helper will not be linked back to the model.
+    #
+    # The +div_radio_button+ code from above can now be used as follows:
+    #
+    #   <%= form_for @person, :builder => MyFormBuilder do |f| %>
+    #     I am a child: <%= f.div_radio_button(:admin, "child") %>

+      # for specifying additional model objects in the same form.
+      #
+      # Although the usage and purpose of +field_for+ is similar to +form_for+'s,
+      # its method signature is slightly different. Like +form_for+, it yields
+      # a FormBuilder object associated with a particular model object to a block,
+      # and within the block allows methods to be called on the builder to
+      # generate fields associated with the model object. Fields may reflect
+      # a model object in two ways - how they are named (hence how submitted
+      # values appear within the +params+ hash in the controller) and what
+      # default values are shown when the form the fields appear in is first
+      # displayed. In order for both of these features to be specified independently,
+      # both an object name (represented by either a symbol or string) and the
+      # object itself can be passed to the method separately -
+      #
+      #   <%= form_for @person do |person_form| %>
+      #     First name: <%= person_form.text_field :first_name %>
+      #     Last name : <%= person_form.text_field :last_name %>
+      #
+      #     <%= fields_for :permission, @person.permission do |permission_fields| %>
+      #       Admin?  : <%= permission_fields.check_box :admin %>
+      #     <% end %>
+      #
+      #     <%= person_form.submit %>
+      #   <% end %>
+      #
+      # In this case, the checkbox field will be represented by an HTML +input+
+      # tag with the +name+ attribute <tt>permission[admin]</tt>, and the submitted
+      # value will appear in the controller as <tt>params[:permission][:admin]</tt>.
+      # If <tt>@person.permission</tt> is an existing record with an attribute
+      # +admin+, the initial state of the checkbox when first displayed will
+      # reflect the value of <tt>@person.permission.admin</tt>.
+      #
+      # Often this can be simplified by passing just the name of the model
+      # object to +fields_for+ -
+      #
+      #   <%= fields_for :permission do |permission_fields| %>
+      #     Admin?: <%= permission_fields.check_box :admin %>
+      #   <% end %>
+      #
+      # ...in which case, if <tt>:permission</tt> also happens to be the name of an
+      # instance variable <tt>@permission</tt>, the initial state of the input
+      # field will reflect the value of that variable's attribute <tt>@permission.admin</tt>.
+      #
+      # Alternatively, you can pass just the model object itself (if the first
+      # argument isn't a string or symbol +fields_for+ will realize that the
+      # name has been omitted) -
+      #
+      #   <%= fields_for @person.permission do |permission_fields| %>
+      #     Admin?: <%= permission_fields.check_box :admin %>
+      #   <% end %>
+      #
+      # and +fields_for+ will derive the required name of the field from the
+      # _class_ of the model object, e.g. if <tt>@person.permission</tt>, is
+      # of class +Permission+, the field will still be named <tt>permission[admin]</tt>.
+      #
+      # Note: This also works for the methods in FormOptionHelper and
+      # DateHelper that are designed to work with an object as base, like
+      # FormOptionHelper#collection_select and DateHelper#datetime_select.
+      #
+      # === Nested Attributes Examples
+      #
+      # When the object belonging to the current scope has a nested attribute
+      # writer for a certain attribute, fields_for will yield a new scope
+      # for that attribute. This allows you to create forms that set or change
+      # the attributes of a parent object and its associations in one go.
+      #
+      # Nested attribute writers are normal setter methods named after an
+      # association. The most common way of defining these writers is either
+      # with +accepts_nested_attributes_for+ in a model definition or by
+      # defining a method with the proper name. For example: the attribute
+      # writer for the association <tt>:address</tt> is called
+      # <tt>address_attributes=</tt>.
+      #
+      # Whether a one-to-one or one-to-many style form builder will be yielded
+      # depends on whether the normal reader method returns a _single_ object
+      # or an _array_ of objects.
+      #
+      # ==== One-to-one
+      #
+      # Consider a Person class which returns a _single_ Address from the
+      # <tt>address</tt> reader method and responds to the
+      # <tt>address_attributes=</tt> writer method:
+      #
+      #   class Person
+      #     def address
+      #       @address
+      #     end
+      #
+      #     def address_attributes=(attributes)
+      #       # Process the attributes hash
+      #     end
+      #   end
+      #
+      # This model can now be used with a nested fields_for, like so:
+      #
+      #   <%= form_for @person do |person_form| %>
+      #     ...
+      #     <%= person_form.fields_for :address do |address_fields| %>
+      #       Street  : <%= address_fields.text_field :street %>
+      #       Zip code: <%= address_fields.text_field :zip_code %>
+      #     <% end %>
+      #     ...
+      #   <% end %>
+      #
+      # When address is already an association on a Person you can use
+      # +accepts_nested_attributes_for+ to define the writer method for you:
+      #
+      #   class Person < ActiveRecord::Base
+      #     has_one :address
+      #     accepts_nested_attributes_for :address
+      #   end
+      #
+      # If you want to destroy the associated model through the form, you have
+      # to enable it first using the <tt>:allow_destroy</tt> option for
+      # +accepts_nested_attributes_for+:
+      #
+      #   class Person < ActiveRecord::Base
+      #     has_one :address
+      #     accepts_nested_attributes_for :address, allow_destroy: true
+      #   end
+      #
+      # Now, when you use a form element with the <tt>_destroy</tt> parameter,
+      # with a value that evaluates to +true+, you will destroy the associated
+      # model (eg. 1, '1', true, or 'true'):
+      #
+      #   <%= form_for @person do |person_form| %>
+      #     ...
+      #     <%= person_form.fields_for :address do |address_fields| %>
+      #       ...
+      #       Delete: <%= address_fields.check_box :_destroy %>
+      #     <% end %>
+      #     ...
+      #   <% end %>
+      #
+      # ==== One-to-many
+      #
+      # Consider a Person class which returns an _array_ of Project instances
+      # from the <tt>projects</tt> reader method and responds to the
+      # <tt>projects_attributes=</tt> writer method:
+      #
+      #   class Person
+      #     def projects
+      #       [@project1, @project2]
+      #     end
+      #
+      #     def projects_attributes=(attributes)
+      #       # Process the attributes hash
+      #     end
+      #   end
+      #
+      # Note that the <tt>projects_attributes=</tt> writer method is in fact
+      # required for fields_for to correctly identify <tt>:projects</tt> as a
+      # collection, and the correct indices to be set in the form markup.
+      #
+      # When projects is already an association on Person you can use
+      # +accepts_nested_attributes_for+ to define the writer method for you:
+      #
+      #   class Person < ActiveRecord::Base
+      #     has_many :projects
+      #     accepts_nested_attributes_for :projects
+      #   end
+      #
+      # This model can now be used with a nested fields_for. The block given to
+      # the nested fields_for call will be repeated for each instance in the
+      # collection:
+      #
+      #   <%= form_for @person do |person_form| %>
+      #     ...
+      #     <%= person_form.fields_for :projects do |project_fields| %>

+      #     <% end %>
+      #     ...
+      #   <% end %>
+      #
+      # It's also possible to specify the instance to be used:
+      #
+      #   <%= form_for @person do |person_form| %>
+      #     ...
+      #     <% @person.projects.each do |project| %>
+      #       <% if project.active? %>
+      #         <%= person_form.fields_for :projects, project do |project_fields| %>
+      #           Name: <%= project_fields.text_field :name %>
+      #         <% end %>
+      #       <% end %>
+      #     <% end %>
+      #     ...
+      #   <% end %>
+      #
+      # Or a collection to be used:
+      #
+      #   <%= form_for @person do |person_form| %>
+      #     ...
+      #     <%= person_form.fields_for :projects, @active_projects do |project_fields| %>
+      #       Name: <%= project_fields.text_field :name %>
+      #     <% end %>
+      #     ...
+      #   <% end %>
+      #
+      # If you want to destroy any of the associated models through the
+      # form, you have to enable it first using the <tt>:allow_destroy</tt>
+      # option for +accepts_nested_attributes_for+:

+      #     accepts_nested_attributes_for :projects, allow_destroy: true
+      #   end
+      #
+      # This will allow you to specify which models to destroy in the
+      # attributes hash by adding a form element for the <tt>_destroy</tt>
+      # parameter with a value that evaluates to +true+
+      # (eg. 1, '1', true, or 'true'):
+      #
+      #   <%= form_for @person do |person_form| %>

+      # Additional options on the label tag can be passed as a hash with +options+. These options will be tagged
+      # onto the HTML as an HTML element attribute as in the example shown, except for the <tt>:value</tt> option, which is designed to
+      # target labels for radio_button tags (where the value is used in the ID of the input tag).
+      #
+      # ==== Examples
+      #   label(:post, :title)
+      #   # => <label for="post_title">Title</label>
+      #
+      # You can localize your labels based on model and attribute names.
+      # For example you can define the following in your locale (e.g. en.yml)
+      #
+      #   helpers:
+      #     label:
+      #       post:
+      #         body: "Write your entire text here"
+      #
+      # Which then will result in
+      #
+      #   label(:post, :body)
+      #   # => <label for="post_body">Write your entire text here</label>
+      #
+      # Localization can also be based purely on the translation of the attribute-name
+      # (if you are using ActiveRecord):
+      #
+      #   activerecord:
+      #     attributes:
+      #       post:
+      #         cost: "Total cost"
+      #
+      #   label(:post, :cost)

+      # Returns a checkbox tag tailored for accessing a specified attribute (identified by +method+) on an object
+      # assigned to the template (identified by +object+). This object must be an instance object (@object) and not a local object.
+      # It's intended that +method+ returns an integer and if that integer is above zero, then the checkbox is checked.
+      # Additional options on the input tag can be passed as a hash with +options+. The +checked_value+ defaults to 1
+      # while the default +unchecked_value+ is set to 0 which is convenient for boolean values.
+      #
+      # ==== Gotcha
+      #
+      # The HTML specification says unchecked check boxes are not successful, and
+      # thus web browsers do not send them. Unfortunately this introduces a gotcha:
+      # if an +Invoice+ model has a +paid+ flag, and in the form that edits a paid
+      # invoice the user unchecks its check box, no +paid+ parameter is sent. So,
+      # any mass-assignment idiom like
+      #
+      #   @invoice.update(params[:invoice])
+      #
+      # wouldn't update the flag.
+      #
+      # To prevent this the helper generates an auxiliary hidden field before
+      # the very check box. The hidden field has the same name and its
+      # attributes mimic an unchecked check box.
+      #
+      # This way, the client either sends only the hidden field (representing
+      # the check box is unchecked), or both fields. Since the HTML specification
+      # says key/value pairs have to be sent in the same order they appear in the
+      # form, and parameters extraction gets the last occurrence of any repeated
+      # key in the query string, that works for ordinary forms.
+      #
+      # Unfortunately that workaround does not work when the check box goes
+      # within an array-like parameter, as in
+      #
+      #   <%= fields_for "project[invoice_attributes][]", invoice, index: nil do |form| %>
+      #     <%= form.check_box :paid %>
+      #     ...
+      #   <% end %>
+      #
+      # because parameter name repetition is precisely what Rails seeks to distinguish
+      # the elements of the array. For each item with a checked check box you
+      # get an extra ghost item with only that attribute, assigned to "0".
+      #
+      # In that case it is preferable to either use +check_box_tag+ or to use
+      # hashes instead of arrays.
+      #
+      #   # Let's say that @post.validated? is 1:

+module ActionView
+  # = Action View Form Option Helpers
+  module Helpers
+    # Provides a number of methods for turning different kinds of containers into a set of option tags.
+    #
+    # The <tt>collection_select</tt>, <tt>select</tt> and <tt>time_zone_select</tt> methods take an <tt>options</tt> parameter, a hash:
+    #
+    # * <tt>:include_blank</tt> - set to true or a prompt string if the first option element of the select element is a blank. Useful if there is not a default value required for the select element.
+    #
+    #   select("post", "category", Post::CATEGORIES, {include_blank: true})
+    #
+    # could become:
+    #
+    #   <select name="post[category]">
+    #     <option></option>
+    #     <option>joke</option>
+    #     <option>poem</option>
+    #   </select>
+    #
+    # Another common case is a select tag for a <tt>belongs_to</tt>-associated object.
+    #
+    # Example with @post.person_id => 2:
+    #
+    #   select("post", "person_id", Person.all.collect {|p| [ p.name, p.id ] }, {include_blank: 'None'})
+    #
+    # could become:
+    #
+    #   <select name="post[person_id]">
+    #     <option value="">None</option>
+    #     <option value="1">David</option>
+    #     <option value="2" selected="selected">Sam</option>
+    #     <option value="3">Tobias</option>
+    #   </select>
+    #
+    # * <tt>:prompt</tt> - set to true or a prompt string. When the select element doesn't have a value yet, this prepends an option with a generic prompt -- "Please select" -- or the given prompt string.
+    #
+    #   select("post", "person_id", Person.all.collect {|p| [ p.name, p.id ] }, {prompt: 'Select Person'})
+    #
+    # could become:
+    #
+    #   <select name="post[person_id]">
+    #     <option value="">Select Person</option>
+    #     <option value="1">David</option>
+    #     <option value="2">Sam</option>
+    #     <option value="3">Tobias</option>
+    #   </select>
+    #
+    # Like the other form helpers, +select+ can accept an <tt>:index</tt> option to manually set the ID used in the resulting output. Unlike other helpers, +select+ expects this
+    # option to be in the +html_options+ parameter.
+    #
+    #   select("album[]", "genre", %w[rap rock country], {}, { index: nil })
+    #
+    # becomes:
+    #
+    #   <select name="album[][genre]" id="album__genre">
+    #     <option value="rap">rap</option>
+    #     <option value="rock">rock</option>
+    #     <option value="country">country</option>
+    #   </select>
+    #
+    # * <tt>:disabled</tt> - can be a single value or an array of values that will be disabled options in the final output.
+    #
+    #   select("post", "category", Post::CATEGORIES, {disabled: 'restricted'})
+    #
+    # could become:
+    #
+    #   <select name="post[category]">
+    #     <option></option>
+    #     <option>joke</option>
+    #     <option>poem</option>
+    #     <option disabled="disabled">restricted</option>
+    #   </select>
+    #
+    # When used with the <tt>collection_select</tt> helper, <tt>:disabled</tt> can also be a Proc that identifies those options that should be disabled.
+    #
+    #   collection_select(:post, :category_id, Category.all, :id, :name, {disabled: lambda{|category| category.archived? }})
+    #
+    # If the categories "2008 stuff" and "Christmas" return true when the method <tt>archived?</tt> is called, this would return:
+    #   <select name="post[category_id]">
+    #     <option value="1" disabled="disabled">2008 stuff</option>
+    #     <option value="2" disabled="disabled">Christmas</option>
+    #     <option value="3">Jokes</option>
+    #     <option value="4">Poems</option>
+    #   </select>
+    #
+    module FormOptionsHelper
+      # ERB::Util can mask some helpers like textilize. Make sure to include them.
+      include TextHelper
+
+      # Create a select tag and a series of contained option tags for the provided object and method.
+      # The option currently held by the object will be selected, provided that the object is available.
+      #
+      # There are two possible formats for the choices parameter, corresponding to other helpers' output:
+      #   * A flat collection: see options_for_select
+      #   * A nested collection: see grouped_options_for_select
+      #
+      # Example with @post.person_id => 1:
+      #   select("post", "person_id", Person.all.collect {|p| [ p.name, p.id ] }, { include_blank: true })
+      #
+      # could become:
+      #
+      #   <select name="post[person_id]">
+      #     <option value=""></option>
+      #     <option value="1" selected="selected">David</option>
+      #     <option value="2">Sam</option>
+      #     <option value="3">Tobias</option>
+      #   </select>
+      #
+      # This can be used to provide a default set of options in the standard way: before rendering the create form, a
+      # new model instance is assigned the default options and bound to @model_name. Usually this model is not saved
+      # to the database. Instead, a second model object is created when the create request is received.
+      # This allows the user to submit a form page more than once with the expected results of creating multiple records.
+      # In addition, this allows a single partial to be used to generate form inputs for both edit and create forms.
+      #
+      # By default, <tt>post.person_id</tt> is the selected option. Specify <tt>selected: value</tt> to use a different selection
+      # or <tt>selected: nil</tt> to leave all options unselected. Similarly, you can specify values to be disabled in the option
+      # tags by specifying the <tt>:disabled</tt> option. This can either be a single value or an array of values to be disabled.
+      #
+      # ==== Gotcha
+      #
+      # The HTML specification says when +multiple+ parameter passed to select and all options got deselected
+      # web browsers do not send any value to server. Unfortunately this introduces a gotcha:
+      # if an +User+ model has many +roles+ and have +role_ids+ accessor, and in the form that edits roles of the user
+      # the user deselects all roles from +role_ids+ multiple select box, no +role_ids+ parameter is sent. So,
+      # any mass-assignment idiom like
+      #
+      #   @user.update(params[:user])
+      #
+      # wouldn't update roles.
+      #
+      # To prevent this the helper generates an auxiliary hidden field before
+      # every multiple select. The hidden field has the same name as multiple select and blank value.
+      #
+      # This way, the client either sends only the hidden field (representing
+      # the deselected multiple select box), or both fields. Since the HTML specification
+      # says key/value pairs have to be sent in the same order they appear in the
+      # form, and parameters extraction gets the last occurrence of any repeated
+      # key in the query string, that works for ordinary forms.
+      #
+      # In case if you don't want the helper to generate this hidden field you can specify
+      # <tt>include_hidden: false</tt> option.
+      #
+      def select(object, method, choices, options = {}, html_options = {})
+        Tags::Select.new(object, method, self, choices, options, html_options).render
+      end
+
+      # Returns <tt><select></tt> and <tt><option></tt> tags for the collection of existing return values of
+      # +method+ for +object+'s class. The value returned from calling +method+ on the instance +object+ will
+      # be selected. If calling +method+ returns +nil+, no selection is made without including <tt>:prompt</tt>
+      # or <tt>:include_blank</tt> in the +options+ hash.
+      #
+      # The <tt>:value_method</tt> and <tt>:text_method</tt> parameters are methods to be called on each member
+      # of +collection+. The return values are used as the +value+ attribute and contents of each
+      # <tt><option></tt> tag, respectively. They can also be any object that responds to +call+, such
+      # as a +proc+, that will be called for each member of the +collection+ to
+      # retrieve the value/text.
+      #
+      # Example object structure for use with this method:
+      #
+      #   class Post < ActiveRecord::Base

+      # Sample usage (selecting the associated Author for an instance of Post, <tt>@post</tt>):
+      #   collection_check_boxes(:post, :author_ids, Author.all, :id, :name_with_initial)
+      #
+      # If <tt>@post.author_ids</tt> is already <tt>[1]</tt>, this would return:
+      #   <input id="post_author_ids_1" name="post[author_ids][]" type="checkbox" value="1" checked="checked" />
+      #   <label for="post_author_ids_1">D. Heinemeier Hansson</label>
+      #   <input id="post_author_ids_2" name="post[author_ids][]" type="checkbox" value="2" />
+      #   <label for="post_author_ids_2">D. Thomas</label>
+      #   <input id="post_author_ids_3" name="post[author_ids][]" type="checkbox" value="3" />
+      #   <label for="post_author_ids_3">M. Clark</label>
+      #   <input name="post[author_ids][]" type="hidden" value="" />
+      #
+      # It is also possible to customize the way the elements will be shown by
+      # giving a block to the method:
+      #   collection_check_boxes(:post, :author_ids, Author.all, :id, :name_with_initial) do |b|
+      #     b.label { b.check_box }
+      #   end
+      #
+      # The argument passed to the block is a special kind of builder for this
+      # collection, which has the ability to generate the label and check box
+      # for the current item in the collection, with proper text and value.
+      # Using it, you can change the label and check box display order or even
+      # use the label as wrapper, as in the example above.
+      #
+      # The builder methods <tt>label</tt> and <tt>check_box</tt> also accept
+      # extra html options:
+      #   collection_check_boxes(:post, :author_ids, Author.all, :id, :name_with_initial) do |b|
+      #     b.label(class: "check_box") { b.check_box(class: "check_box") }
+      #   end
+      #
+      # There are also three special methods available: <tt>object</tt>, <tt>text</tt> and
+      # <tt>value</tt>, which are the current item being rendered, its text and value methods,
+      # respectively. You can use them like this:
+      #   collection_check_boxes(:post, :author_ids, Author.all, :id, :name_with_initial) do |b|
+      #      b.label(:"data-value" => b.value) { b.check_box + b.text }

+module ActionView
+  # = Action View Form Tag Helpers
+  module Helpers
+    # Provides a number of methods for creating form tags that don't rely on an Active Record object assigned to the template like
+    # FormHelper does. Instead, you provide the names and values manually.
+    #
+    # NOTE: The HTML options <tt>disabled</tt>, <tt>readonly</tt>, and <tt>multiple</tt> can all be treated as booleans. So specifying
+    # <tt>disabled: true</tt> will give <tt>disabled="disabled"</tt>.
+    module FormTagHelper
+      extend ActiveSupport::Concern
+
+      include UrlHelper
+      include TextHelper
+
+      mattr_accessor :embed_authenticity_token_in_remote_forms
+      self.embed_authenticity_token_in_remote_forms = false
+
+      # Starts a form tag that points the action to an url configured with <tt>url_for_options</tt> just like
+      # ActionController::Base#url_for. The method for the form defaults to POST.
+      #
+      # ==== Options
+      # * <tt>:multipart</tt> - If set to true, the enctype is set to "multipart/form-data".
+      # * <tt>:method</tt> - The method to use when submitting the form, usually either "get" or "post".
+      #   If "patch", "put", "delete", or another verb is used, a hidden input with name <tt>_method</tt>
+      #   is added to simulate the verb over post.
+      # * <tt>:authenticity_token</tt> - Authenticity token to use in the form. Use only if you need to
+      #   pass custom authenticity token string, or to not add authenticity_token field at all
+      #   (by passing <tt>false</tt>).  Remote forms may omit the embedded authenticity token
+      #   by setting <tt>config.action_view.embed_authenticity_token_in_remote_forms = false</tt>.
+      #   This is helpful when you're fragment-caching the form. Remote forms get the
+      #   authenticity token from the <tt>meta</tt> tag, so embedding is unnecessary unless you
+      #   support browsers without JavaScript.
+      # * A list of parameters to feed to the URL the form will be posted to.
+      # * <tt>:remote</tt> - If set to true, will allow the Unobtrusive JavaScript drivers to control the
+      #   submit behavior. By default this behavior is an ajax submit.
+      #
+      # ==== Examples
+      #   form_tag('/posts')
+      #   # => <form action="/posts" method="post">
+      #
+      #   form_tag('/posts/1', method: :put)

+      #
+      #   form_tag('/upload', multipart: true)
+      #   # => <form action="/upload" method="post" enctype="multipart/form-data">
+      #
+      #   <%= form_tag('/posts') do -%>
+      #     <div><%= submit_tag 'Save' %></div>
+      #   <% end -%>
+      #   # => <form action="/posts" method="post"><div><input type="submit" name="commit" value="Save" /></div></form>
+      #

+      #
+      #   form_tag('http://far.away.com/form', authenticity_token: "cf50faa3fe97702ca1ae")
+      #   # form with custom authenticity token

+      # Creates a dropdown selection box, or if the <tt>:multiple</tt> option is set to true, a multiple
+      # choice selection box.
+      #
+      # Helpers::FormOptions can be used to create common select boxes such as countries, time zones, or
+      # associated records. <tt>option_tags</tt> is a string containing the option tags for the select box.
+      #
+      # ==== Options
+      # * <tt>:multiple</tt> - If set to true the selection will allow multiple choices.
+      # * <tt>:disabled</tt> - If set to true, the user will not be able to use this input.
+      # * <tt>:include_blank</tt> - If set to true, an empty option will be created.
+      # * <tt>:prompt</tt> - Create a prompt option with blank value and the text asking user to select something
+      # * Any other key creates standard HTML attributes for the tag.
+      #
+      # ==== Examples
+      #   select_tag "people", options_from_collection_for_select(@people, "id", "name")

+      # Returns an empty HTML tag of type +name+ which by default is XHTML
+      # compliant. Set +open+ to true to create an open tag compatible
+      # with HTML 4.0 and below. Add HTML attributes by passing an attributes
+      # hash to +options+. Set +escape+ to false to disable attribute value
+      # escaping.
+      #
+      # ==== Options
+      # You can use symbols or strings for the attribute names.
+      #
+      # Use +true+ with boolean attributes that can render with no value, like
+      # +disabled+ and +readonly+.
+      #
+      # HTML5 <tt>data-*</tt> attributes can be set with a single +data+ key
+      # pointing to a hash of sub-attributes.
+      #
+      # To play nicely with JavaScript conventions sub-attributes are dasherized.
+      # For example, a key +user_id+ would render as <tt>data-user-id</tt> and
+      # thus accessed as <tt>dataset.userId</tt>.
+      #
+      # Values are encoded to JSON, with the exception of strings and symbols.
+      # This may come in handy when using jQuery's HTML5-aware <tt>.data()</tt>
+      # from 1.4.3.
+      #
+      # ==== Examples
+      #   tag("br")
+      #   # => <br />
+      #
+      #   tag("br", nil, true)
+      #   # => <br>
+      #
+      #   tag("input", type: 'text', disabled: true)
+      #   # => <input type="text" disabled="disabled" />
+      #
+      #   tag("img", src: "open & shut.png")
+      #   # => <img src="open &amp; shut.png" />
+      #
+      #   tag("img", {src: "open &amp; shut.png"}, false, false)
+      #   # => <img src="open &amp; shut.png" />
+      #
+      #   tag("div", data: {name: 'Stephen', city_state: %w(Chicago IL)})
+      #   # => <div data-name="Stephen" data-city-state="[&quot;Chicago&quot;,&quot;IL&quot;]" />

+
+      # Returns an HTML block tag of type +name+ surrounding the +content+. Add
+      # HTML attributes by passing an attributes hash to +options+.
+      # Instead of passing the content as an argument, you can also use a block
+      # in which case, you pass your +options+ as the second parameter.
+      # Set escape to false to disable attribute value escaping.
+      #
+      # ==== Options
+      # The +options+ hash is used with attributes with no value like (<tt>disabled</tt> and
+      # <tt>readonly</tt>), which you can give a value of true in the +options+ hash. You can use
+      # symbols or strings for the attribute names.
+      #
+      # ==== Examples
+      #   content_tag(:p, "Hello world!")
+      #    # => <p>Hello world!</p>
+      #   content_tag(:div, content_tag(:p, "Hello world!"), class: "strong")

+  module Helpers #:nodoc:
+    # The TextHelper module provides a set of methods for filtering, formatting
+    # and transforming strings, which can reduce the amount of inline Ruby code in
+    # your views. These helper methods extend Action View making them callable
+    # within your template files.
+    #
+    # ==== Sanitization
+    #
+    # Most text helpers by default sanitize the given content, but do not escape it.
+    # This means HTML tags will appear in the page but all malicious code will be removed.
+    # Let's look at some examples using the +simple_format+ method:
+    #
+    #   simple_format('<a href="http://example.com/">Example</a>')
+    #   # => "<p><a href=\"http://example.com/\">Example</a></p>"
+    #
+    #   simple_format('<a href="javascript:alert(\'no!\')">Example</a>')
+    #   # => "<p><a>Example</a></p>"
+    #
+    # If you want to escape all content, you should invoke the +h+ method before
+    # calling the text helper.
+    #
+    #   simple_format h('<a href="http://example.com/">Example</a>')
+    #   # => "<p>&lt;a href=\"http://example.com/\"&gt;Example&lt;/a&gt;</p>"
+    module TextHelper
+      extend ActiveSupport::Concern
+
+      include SanitizeHelper
+      include TagHelper
+      # The preferred method of outputting text in your views is to use the
+      # <%= "text" %> eRuby syntax. The regular _puts_ and _print_ methods
+      # do not operate as expected in an eRuby code block. If you absolutely must
+      # output text within a non-output code block (i.e., <% %>), you can use the concat method.
+      #
+      #   <%
+      #       concat "hello"
+      #       # is the equivalent of <%= "hello" %>
+      #
+      #       if logged_in
+      #         concat "Logged in!"
+      #       else

+      #
+      # First, it'll pass the <tt>rescue_format: :html</tt> option to I18n so that any
+      # thrown +MissingTranslation+ messages will be turned into inline spans that
+      #
+      #   * have a "translation-missing" class set,
+      #   * contain the missing key as a title attribute and
+      #   * a titleized version of the last key segment as a text.
+      #
+      # E.g. the value returned for a missing translation key :"blog.post.title" will be
+      # <span class="translation_missing" title="translation missing: en.blog.post.title">Title</span>.
+      # This way your views will display rather reasonable strings but it will still
+      # be easy to spot missing translations.
+      #
+      # Second, it'll scope the key by the current partial if the key starts
+      # with a period. So if you call <tt>translate(".foo")</tt> from the
+      # <tt>people/index.html.erb</tt> template, you'll actually be calling
+      # <tt>I18n.translate("people.index.foo")</tt>. This makes it less repetitive
+      # to translate many keys within the same partials and gives you a simple framework
+      # for scoping them consistently. If you don't prepend the key with a period,
+      # nothing is converted.
+      #
+      # Third, it'll mark the translation as safe HTML if the key has the suffix
+      # "_html" or the last element of the key is the word "html". For example,
+      # calling translate("footer_html") or translate("footer.html") will return
+      # a safe HTML string that won't be escaped by other HTML helper methods. This

+      # Creates a link tag of the given +name+ using a URL created by the set of +options+.
+      # See the valid options in the documentation for +url_for+. It's also possible to

+      # value of the String as the href for the link. Using a <tt>:back</tt> Symbol instead
+      # of an options hash will generate a link to the referrer (a JavaScript back link
+      # will be used in place of a referrer if none exists). If +nil+ is passed as the name
+      # the value of the link itself will become the name.
+      #
+      # ==== Signatures
+      #
+      #   link_to(body, url, html_options = {})
+      #     # url is a String; you can use URL helpers like
+      #     # posts_path
+      #
+      #   link_to(body, url_options = {}, html_options = {})
+      #     # url_options, except :method, is passed to url_for
+      #
+      #   link_to(options = {}, html_options = {}) do
+      #     # name
+      #   end
+      #
+      #   link_to(url, html_options = {}) do
+      #     # name
+      #   end
+      #
+      # ==== Options
+      # * <tt>:data</tt> - This option can be used to add custom data attributes.
+      # * <tt>method: symbol of HTTP verb</tt> - This modifier will dynamically
+      #   create an HTML form and immediately submit the form for processing using
+      #   the HTTP verb specified. Useful for having links perform a POST operation
+      #   in dangerous actions like deleting a record (which search bots can follow
+      #   while spidering your site). Supported verbs are <tt>:post</tt>, <tt>:delete</tt>, <tt>:patch</tt>, and <tt>:put</tt>.
+      #   Note that if the user has JavaScript disabled, the request will fall back
+      #   to using GET. If <tt>href: '#'</tt> is used and the user has JavaScript
+      #   disabled clicking the link will have no effect. If you are relying on the
+      #   POST behavior, you should check for it in your controller's action by using
+      #   the request object's methods for <tt>post?</tt>, <tt>delete?</tt>, <tt>:patch</tt>, or <tt>put?</tt>.
+      # * <tt>remote: true</tt> - This will allow the unobtrusive JavaScript
+      #   driver to make an Ajax request to the URL in question instead of following
+      #   the link. The drivers each provide mechanisms for listening for the
+      #   completion of the Ajax request and performing JavaScript operations once
+      #   they're complete
+      #
+      # ==== Data attributes
+      #
+      # * <tt>confirm: 'question?'</tt> - This will allow the unobtrusive JavaScript
+      #   driver to prompt with the question specified. If the user accepts, the link is
+      #   processed normally, otherwise no action is taken.
+      # * <tt>:disable_with</tt> - Value of this parameter will be
+      #   used as the value for a disabled version of the submit
+      #   button when the form is submitted. This feature is provided
+      #   by the unobtrusive JavaScript driver.
+      #
+      # ==== Examples
+      # Because it relies on +url_for+, +link_to+ supports both older-style controller/action/id arguments
+      # and newer RESTful routes. Current Rails style favors RESTful routes whenever possible, so base
+      # your application on resources and use
+      #
+      #   link_to "Profile", profile_path(@profile)
+      #   # => <a href="/profiles/1">Profile</a>
+      #
+      # or the even pithier
+      #
+      #   link_to "Profile", @profile
+      #   # => <a href="/profiles/1">Profile</a>
+      #
+      # in place of the older more verbose, non-resource-oriented
+      #
+      #   link_to "Profile", controller: "profiles", action: "show", id: @profile
+      #   # => <a href="/profiles/show/1">Profile</a>
+      #
+      # Similarly,
+      #
+      #   link_to "Profiles", profiles_path
+      #   # => <a href="/profiles">Profiles</a>
+      #
+      # is better than
+      #
+      #   link_to "Profiles", controller: "profiles"
+      #   # => <a href="/profiles">Profiles</a>
+      #
+      # You can use a block as well if your link target is hard to fit into the name parameter. ERB example:
+      #
+      #   <%= link_to(@profile) do %>
+      #     <strong><%= @profile.name %></strong> -- <span>Check it out!</span>
+      #   <% end %>
+      #   # => <a href="/profiles/1">
+      #          <strong>David</strong> -- <span>Check it out!</span>
+      #        </a>
+      #
+      # Classes and ids for CSS are easy to produce:
+      #
+      #   link_to "Articles", articles_path, id: "news", class: "article"
+      #   # => <a href="/articles" class="article" id="news">Articles</a>
+      #
+      # Be careful when using the older argument style, as an extra literal hash is needed:
+      #
+      #   link_to "Articles", { controller: "articles" }, id: "news", class: "article"
+      #   # => <a href="/articles" class="article" id="news">Articles</a>
+      #
+      # Leaving the hash off gives the wrong link:
+      #
+      #   link_to "WRONG!", controller: "articles", id: "news", class: "article"
+      #   # => <a href="/articles/index/news?class=article">WRONG!</a>
+      #
+      # +link_to+ can also produce links with anchors or query strings:
+      #
+      #   link_to "Comment wall", profile_path(@profile, anchor: "wall")
+      #   # => <a href="/profiles/1#wall">Comment wall</a>
+      #
+      #   link_to "Ruby on Rails search", controller: "searches", query: "ruby on rails"
+      #   # => <a href="/searches?query=ruby+on+rails">Ruby on Rails search</a>
+      #
+      #   link_to "Nonsense search", searches_path(foo: "bar", baz: "quux")
+      #   # => <a href="/searches?foo=bar&amp;baz=quux">Nonsense search</a>
+      #
+      # The only option specific to +link_to+ (<tt>:method</tt>) is used as follows:
+      #
+      #   link_to("Destroy", "http://www.example.com", method: :delete)
+      #   # => <a href='http://www.example.com' rel="nofollow" data-method="delete">Destroy</a>
+      #
+      # You can also use custom data attributes using the <tt>:data</tt> option:
+      #
+      #   link_to "Visit Other Site", "http://www.rubyonrails.org/", data: { confirm: "Are you sure?" }
+      #   # => <a href="http://www.rubyonrails.org/" data-confirm="Are you sure?">Visit Other Site</a>
+      def link_to(name = nil, options = nil, html_options = nil, &block)
+        html_options, options = options, name if block_given?
+        options ||= {}
+
+        html_options = convert_options_to_data_attributes(options, html_options)
+
+        url = url_for(options)
+        html_options['href'] ||= url
+
+        content_tag(:a, name || url, html_options, &block)
+      end
+
+      # Generates a form containing a single button that submits to the URL created
+      # by the set of +options+. This is the safest method to ensure links that
+      # cause changes to your data are not triggered by search bots or accelerators.
+      # If the HTML button does not work with your layout, you can also consider
+      # using the +link_to+ method with the <tt>:method</tt> modifier as described in
+      # the +link_to+ documentation.
+      #
+      # By default, the generated form element has a class name of <tt>button_to</tt>
+      # to allow styling of the form itself and its children. This can be changed
+      # using the <tt>:form_class</tt> modifier within +html_options+. You can control
+      # the form submission and input element behavior using +html_options+.
+      # This method accepts the <tt>:method</tt> modifier described in the +link_to+ documentation.
+      # If no <tt>:method</tt> modifier is given, it will default to performing a POST operation.
+      # You can also disable the button by passing <tt>disabled: true</tt> in +html_options+.
+      # If you are using RESTful routes, you can pass the <tt>:method</tt>
+      # to change the HTTP verb used to submit the form.
+      #
+      # ==== Options
+      # The +options+ hash accepts the same options as +url_for+.
+      #
+      # There are a few special +html_options+:
+      # * <tt>:method</tt> - Symbol of HTTP verb. Supported verbs are <tt>:post</tt>, <tt>:get</tt>,
+      #   <tt>:delete</tt>, <tt>:patch</tt>, and <tt>:put</tt>. By default it will be <tt>:post</tt>.
+      # * <tt>:disabled</tt> - If set to true, it will generate a disabled button.
+      # * <tt>:data</tt> - This option can be used to add custom data attributes.
+      # * <tt>:remote</tt> -  If set to true, will allow the Unobtrusive JavaScript drivers to control the
+      #   submit behavior. By default this behavior is an ajax submit.
+      # * <tt>:form</tt> - This hash will be form attributes
+      # * <tt>:form_class</tt> - This controls the class of the form within which the submit button will
+      #   be placed
+      #
+      # ==== Data attributes
+      #
+      # * <tt>:confirm</tt> - This will use the unobtrusive JavaScript driver to
+      #   prompt with the question specified. If the user accepts, the link is
+      #   processed normally, otherwise no action is taken.
+      # * <tt>:disable_with</tt> - Value of this parameter will be
+      #   used as the value for a disabled version of the submit
+      #   button when the form is submitted. This feature is provided
+      #   by the unobtrusive JavaScript driver.
+      #
+      # ==== Examples
+      #   <%= button_to "New", action: "new" %>

+      # specialize the default behavior (e.g., show a "Start Here" link rather
+      # than the link's text).
+      #
+      # ==== Examples
+      # Let's say you have a navigation menu...
+      #
+      #   <ul id="navbar">
+      #     <li><%= link_to_unless_current("Home", { action: "index" }) %></li>
+      #     <li><%= link_to_unless_current("About Us", { action: "about" }) %></li>

+      #   <ul id="navbar">
+      #     <li><a href="/controller/index">Home</a></li>
+      #     <li>About Us</li>
+      #   </ul>
+      #
+      # ...but if in the "index" action, it will render:
+      #
+      #   <ul id="navbar">
+      #     <li>Home</li>
+      #     <li><a href="/controller/about">About Us</a></li>

+      #
+      # The implicit block given to +link_to_unless_current+ is evaluated if the current
+      # action is the action given. So, if we had a comments page and wanted to render a
+      # "Go Back" link instead of a link to the comments page, we could do something like this...
+      #
+      #    <%=
+      #        link_to_unless_current("Comment", { controller: "comments", action: "new" }) do

+      # Creates a link tag of the given +name+ using a URL created by the set of
+      # +options+ unless +condition+ is true, in which case only the name is

+      # than just the plaintext link text), you can pass a block that
+      # accepts the name or the full argument list for +link_to_unless+.
+      #

+      #
+      # +mail_to+ has several methods for customizing the email itself by

+      #
+      # ==== Options
+      # * <tt>:subject</tt> - Preset the subject line of the email.
+      # * <tt>:body</tt> - Preset the body of the email.
+      # * <tt>:cc</tt> - Carbon Copy additional recipients on the email.
+      # * <tt>:bcc</tt> - Blind Carbon Copy additional recipients on the email.
+      #
+      # ==== Obfuscation
+      # Prior to Rails 4.0, +mail_to+ provided options for encoding the address
+      # in order to hinder email harvesters.  To take advantage of these options,
+      # install the +actionview-encoded_mail_to+ gem.
+      #
+      # ==== Examples
+      #   mail_to "me@domain.com"
+      #   # => <a href="mailto:me@domain.com">me@domain.com</a>
+      #
+      #   mail_to "me@domain.com", "My email"
+      #   # => <a href="mailto:me@domain.com">My email</a>
+      #
+      #   mail_to "me@domain.com", "My email", cc: "ccaddress@domain.com",
+      #            subject: "This is an example email"
+      #   # => <a href="mailto:me@domain.com?cc=ccaddress@domain.com&subject=This%20is%20an%20example%20email">My email</a>
+      #
+      # You can use a block as well if your link target is hard to fit into the name parameter. ERB example:
+      #
+      #   <%= mail_to "me@domain.com" do %>
+      #     <strong>Email me:</strong> <span>me@domain.com</span>

+require 'thread_safe'
+
+module ActionView
+  # = Action View Partials
+  #
+  # There's also a convenience method for rendering sub templates within the current controller that depends on a
+  # single object (we call this kind of sub templates for partials). It relies on the fact that partials should
+  # follow the naming convention of being prefixed with an underscore -- as to separate them from regular
+  # templates that could be rendered on their own.
+  #
+  # In a template for Advertiser#account:
+  #
+  #  <%= render partial: "account" %>
+  #
+  # This would render "advertiser/_account.html.erb".
+  #
+  # In another template for Advertiser#buy, we could have:
+  #
+  #   <%= render partial: "account", locals: { account: @buyer } %>
+  #
+  #   <% @advertisements.each do |ad| %>
+  #     <%= render partial: "ad", locals: { ad: ad } %>
+  #   <% end %>
+  #
+  # This would first render "advertiser/_account.html.erb" with @buyer passed in as the local variable +account+, then
+  # render "advertiser/_ad.html.erb" and pass the local variable +ad+ to the template for display.
+  #
+  # == The :as and :object options
+  #
+  # By default <tt>ActionView::PartialRenderer</tt> doesn't have any local variables.
+  # The <tt>:object</tt> option can be used to pass an object to the partial. For instance:
+  #
+  #   <%= render partial: "account", object: @buyer %>
+  #
+  # would provide the <tt>@buyer</tt> object to the partial, available under the local variable +account+ and is
+  # equivalent to:
+  #
+  #   <%= render partial: "account", locals: { account: @buyer } %>
+  #
+  # With the <tt>:as</tt> option we can specify a different name for said local variable. For example, if we
+  # wanted it to be +user+ instead of +account+ we'd do:
+  #
+  #   <%= render partial: "account", object: @buyer, as: 'user' %>
+  #
+  # This is equivalent to
+  #
+  #   <%= render partial: "account", locals: { user: @buyer } %>
+  #
+  # == Rendering a collection of partials
+  #
+  # The example of partial use describes a familiar pattern where a template needs to iterate over an array and
+  # render a sub template for each of the elements. This pattern has been implemented as a single method that
+  # accepts an array and renders a partial by the same name as the elements contained within. So the three-lined
+  # example in "Using partials" can be rewritten with a single line:
+  #
+  #   <%= render partial: "ad", collection: @advertisements %>
+  #
+  # This will render "advertiser/_ad.html.erb" and pass the local variable +ad+ to the template for display. An
+  # iteration counter will automatically be made available to the template with a name of the form
+  # +partial_name_counter+. In the case of the example above, the template would be fed +ad_counter+.
+  #
+  # The <tt>:as</tt> option may be used when rendering partials.
+  #
+  # You can specify a partial to be rendered between elements via the <tt>:spacer_template</tt> option.
+  # The following example will render <tt>advertiser/_ad_divider.html.erb</tt> between each ad partial:
+  #
+  #   <%= render partial: "ad", collection: @advertisements, spacer_template: "ad_divider" %>
+  #
+  # If the given <tt>:collection</tt> is nil or empty, <tt>render</tt> will return nil. This will allow you
+  # to specify a text which will displayed instead by using this form:
+  #
+  #   <%= render(partial: "ad", collection: @advertisements) || "There's no ad to be displayed" %>
+  #
+  # NOTE: Due to backwards compatibility concerns, the collection can't be one of hashes. Normally you'd also
+  # just keep domain objects, like Active Records, in there.
+  #
+  # == Rendering shared partials
+  #
+  # Two controllers can share a set of partials and render them like this:
+  #
+  #   <%= render partial: "advertisement/ad", locals: { ad: @advertisement } %>
+  #
+  # This will render the partial "advertisement/_ad.html.erb" regardless of which controller this is being called from.
+  #
+  # == Rendering objects that respond to `to_partial_path`
+  #
+  # Instead of explicitly naming the location of a partial, you can also let PartialRenderer do the work
+  # and pick the proper path by checking `to_partial_path` method.
+  #
+  #  # @account.to_partial_path returns 'accounts/account', so it can be used to replace:
+  #  # <%= render partial: "accounts/account", locals: { account: @account} %>
+  #  <%= render partial: @account %>
+  #
+  #  # @posts is an array of Post instances, so every post record returns 'posts/post' on `to_partial_path`,
+  #  # that's why we can replace:
+  #  # <%= render partial: "posts/post", collection: @posts %>
+  #  <%= render partial: @posts %>
+  #
+  # == Rendering the default case
+  #
+  # If you're not going to be using any of the options like collections or layouts, you can also use the short-hand
+  # defaults of render to render partials. Examples:
+  #
+  #  # Instead of <%= render partial: "account" %>
+  #  <%= render "account" %>
+  #
+  #  # Instead of <%= render partial: "account", locals: { account: @buyer } %>
+  #  <%= render "account", account: @buyer %>
+  #
+  #  # @account.to_partial_path returns 'accounts/account', so it can be used to replace:
+  #  # <%= render partial: "accounts/account", locals: { account: @account} %>
+  #  <%= render @account %>
+  #
+  #  # @posts is an array of Post instances, so every post record returns 'posts/post' on `to_partial_path`,
+  #  # that's why we can replace:
+  #  # <%= render partial: "posts/post", collection: @posts %>
+  #  <%= render @posts %>
+  #
+  # == Rendering partials with layouts
+  #
+  # Partials can have their own layouts applied to them. These layouts are different than the ones that are
+  # specified globally for the entire action, but they work in a similar fashion. Imagine a list with two types
+  # of users:
+  #
+  #   <%# app/views/users/index.html.erb &>
+  #   Here's the administrator:
+  #   <%= render partial: "user", layout: "administrator", locals: { user: administrator } %>
+  #
+  #   Here's the editor:
+  #   <%= render partial: "user", layout: "editor", locals: { user: editor } %>
+  #
+  #   <%# app/views/users/_user.html.erb &>
+  #   Name: <%= user.name %>
+  #
+  #   <%# app/views/users/_administrator.html.erb &>
+  #   <div id="administrator">
+  #     Budget: $<%= user.budget %>
+  #     <%= yield %>
+  #   </div>
+  #
+  #   <%# app/views/users/_editor.html.erb &>
+  #   <div id="editor">
+  #     Deadline: <%= user.deadline %>
+  #     <%= yield %>
+  #   </div>
+  #
+  # ...this will return:
+  #
+  #   Here's the administrator:
+  #   <div id="administrator">
+  #     Budget: $<%= user.budget %>
+  #     Name: <%= user.name %>
+  #   </div>
+  #
+  #   Here's the editor:
+  #   <div id="editor">
+  #     Deadline: <%= user.deadline %>
+  #     Name: <%= user.name %>
+  #   </div>
+  #
+  # If a collection is given, the layout will be rendered once for each item in
+  # the collection. Just think these two snippets have the same output:
+  #
+  #   <%# app/views/users/_user.html.erb %>

+    # instead of the fully qualified URL like "http://example.com/controller/action".

+    # ==== Options
+    # * <tt>:anchor</tt> - Specifies the anchor name to be appended to the path.
+    # * <tt>:only_path</tt> - If true, returns the relative URL (omitting the protocol, host name, and port) (<tt>true</tt> by default unless <tt>:host</tt> is specified).
+    # * <tt>:trailing_slash</tt> - If true, adds a trailing slash, as in "/archive/2005/". Note that this
+    #   is currently not recommended since it breaks caching.
+    # * <tt>:host</tt> - Overrides the default (current) host if provided.

+module ActionView
+  # = Action View Template
+  class Template
+    extend ActiveSupport::Autoload
+
+    # === Encodings in ActionView::Template
+    #
+    # ActionView::Template is one of a few sources of potential
+    # encoding issues in Rails. This is because the source for
+    # templates are usually read from disk, and Ruby (like most
+    # encoding-aware programming languages) assumes that the
+    # String retrieved through File IO is encoded in the
+    # <tt>default_external</tt> encoding. In Rails, the default
+    # <tt>default_external</tt> encoding is UTF-8.
+    #
+    # As a result, if a user saves their template as ISO-8859-1
+    # (for instance, using a non-Unicode-aware text editor),
+    # and uses characters outside of the ASCII range, their
+    # users will see diamonds with question marks in them in
+    # the browser.
+    #
+    # For the rest of this documentation, when we say "UTF-8",
+    # we mean "UTF-8 or whatever the default_internal encoding
+    # is set to". By default, it will be UTF-8.
+    #
+    # To mitigate this problem, we use a few strategies:
+    # 1. If the source is not valid UTF-8, we raise an exception
+    #    when the template is compiled to alert the user
+    #    to the problem.
+    # 2. The user can specify the encoding using Ruby-style
+    #    encoding comments in any template engine. If such
+    #    a comment is supplied, Rails will apply that encoding
+    #    to the resulting compiled source returned by the
+    #    template handler.
+    # 3. In all cases, we transcode the resulting String to
+    #    the UTF-8.
+    #
+    # This means that other parts of Rails can always assume
+    # that templates are encoded in UTF-8, even if the original
+    # source of the template was not UTF-8.
+    #
+    # From a user's perspective, the easiest thing to do is
+    # to save your templates as UTF-8. If you do this, you
+    # do not need to do anything else for things to "just work".
+    #
+    # === Instructions for template handlers
+    #
+    # The easiest thing for you to do is to simply ignore
+    # encodings. Rails will hand you the template source
+    # as the default_internal (generally UTF-8), raising
+    # an exception for the user before sending the template
+    # to you if it could not determine the original encoding.
+    #
+    # For the greatest simplicity, you can support only
+    # UTF-8 as the <tt>default_internal</tt>. This means
+    # that from the perspective of your handler, the
+    # entire pipeline is just UTF-8.
+    #
+    # === Advanced: Handlers with alternate metadata sources
+    #
+    # If you want to provide an alternate mechanism for
+    # specifying encodings (like ERB does via <%# encoding: ... %>),
+    # you may indicate that you will handle encodings yourself
+    # by implementing <tt>self.handles_encoding?</tt>
+    # on your handler.
+    #
+    # If you do, Rails will not try to encode the String
+    # into the default_internal, passing you the unaltered
+    # bytes tagged with the assumed encoding (from
+    # default_external).
+    #
+    # In this case, make sure you return a String from
+    # your handler encoded in the default_internal. Since
+    # you are handling out-of-band metadata, you are
+    # also responsible for alerting the user to any
+    # problems with converting the user's data to
+    # the <tt>default_internal</tt>.
+    #
+    # To do so, simply raise +WrongEncodingError+ as follows:
+    #
+    #     raise WrongEncodingError.new(
+    #       problematic_string,
+    #       expected_encoding

+  # A resolver that loads files from the filesystem. It allows setting your own
+  # resolving pattern. Such pattern can be a glob string supported by some variables.
+  #
+  # ==== Examples
+  #
+  # Default pattern, loads views the same way as previous versions of rails, eg. when you're
+  # looking for `users/new` it will produce query glob: `users/new{.{en},}{.{html,js},}{.{erb,haml},}`
+  #
+  #   FileSystemResolver.new("/path/to/views", ":prefix/:action{.:locale,}{.:formats,}{.:handlers,}")
+  #
+  # This one allows you to keep files with different formats in separate subdirectories,
+  # eg. `users/new.html` will be loaded from `users/html/new.erb` or `users/new.html.erb`,
+  # `users/new.js` from `users/js/new.erb` or `users/new.js.erb`, etc.
+  #
+  #   FileSystemResolver.new("/path/to/views", ":prefix/{:formats/,}:action{.:locale,}{.:formats,}{.:handlers,}")
+  #
+  # If you don't specify a pattern then the default will be used.
+  #
+  # In order to use any of the customized resolvers above in a Rails application, you just need
+  # to configure ActionController::Base.view_paths in an initializer, for example:
+  #
+  #   ActionController::Base.view_paths = FileSystemResolver.new(
+  #     Rails.root.join("app/views"),
+  #     ":prefix{/:locale}/:action{.:formats,}{.:handlers,}"
+  #   )
+  #
+  # ==== Pattern format and variables
+  #
+  # Pattern has to be a valid glob string, and it allows you to use the
+  # following variables:
+  #
+  # * <tt>:prefix</tt> - usually the controller path
+  # * <tt>:action</tt> - name of the action
+  # * <tt>:locale</tt> - possible locale versions
+  # * <tt>:formats</tt> - possible request formats (for example html, json, xml...)
+  # * <tt>:handlers</tt> - possible handlers (for example erb, haml, builder...)

+
+module HTML
+
+  # Selects HTML elements using CSS 2 selectors.
+  #
+  # The +Selector+ class uses CSS selector expressions to match and select
+  # HTML elements.
+  #
+  # For example:
+  #   selector = HTML::Selector.new "form.login[action=/login]"
+  # creates a new selector that matches any +form+ element with the class
+  # +login+ and an attribute +action+ with the value <tt>/login</tt>.
+  #
+  # === Matching Elements
+  #
+  # Use the #match method to determine if an element matches the selector.
+  #
+  # For simple selectors, the method returns an array with that element,
+  # or +nil+ if the element does not match. For complex selectors (see below)
+  # the method returns an array with all matched elements, of +nil+ if no
+  # match found.
+  #
+  # For example:
+  #   if selector.match(element)
+  #     puts "Element is a login form"
+  #   end
+  #
+  # === Selecting Elements
+  #
+  # Use the #select method to select all matching elements starting with
+  # one element and going through all children in depth-first order.
+  #
+  # This method returns an array of all matching elements, an empty array
+  # if no match is found
+  #
+  # For example:
+  #   selector = HTML::Selector.new "input[type=text]"
+  #   matches = selector.select(element)
+  #   matches.each do |match|
+  #     puts "Found text field with name #{match.attributes['name']}"
+  #   end
+  #
+  # === Expressions
+  #
+  # Selectors can match elements using any of the following criteria:
+  # * <tt>name</tt> -- Match an element based on its name (tag name).
+  #   For example, <tt>p</tt> to match a paragraph. You can use <tt>*</tt>
+  #   to match any element.
+  # * <tt>#</tt><tt>id</tt> -- Match an element based on its identifier (the
+  #   <tt>id</tt> attribute). For example, <tt>#</tt><tt>page</tt>.
+  # * <tt>.class</tt> -- Match an element based on its class name, all
+  #   class names if more than one specified.
+  # * <tt>[attr]</tt> -- Match an element that has the specified attribute.
+  # * <tt>[attr=value]</tt> -- Match an element that has the specified
+  #   attribute and value. (More operators are supported see below)
+  # * <tt>:pseudo-class</tt> -- Match an element based on a pseudo class,
+  #   such as <tt>:nth-child</tt> and <tt>:empty</tt>.
+  # * <tt>:not(expr)</tt> -- Match an element that does not match the
+  #   negation expression.
+  #
+  # When using a combination of the above, the element name comes first
+  # followed by identifier, class names, attributes, pseudo classes and
+  # negation in any order. Do not separate these parts with spaces!
+  # Space separation is used for descendant selectors.
+  #
+  # For example:
+  #   selector = HTML::Selector.new "form.login[action=/login]"
+  # The matched element must be of type +form+ and have the class +login+.
+  # It may have other classes, but the class +login+ is required to match.
+  # It must also have an attribute called +action+ with the value
+  # <tt>/login</tt>.
+  #
+  # This selector will match the following element:
+  #   <form class="login form" method="post" action="/login">
+  # but will not match the element:
+  #   <form method="post" action="/logout">
+  #
+  # === Attribute Values
+  #
+  # Several operators are supported for matching attributes:
+  # * <tt>name</tt> -- The element must have an attribute with that name.
+  # * <tt>name=value</tt> -- The element must have an attribute with that
+  #   name and value.
+  # * <tt>name^=value</tt> -- The attribute value must start with the
+  #   specified value.
+  # * <tt>name$=value</tt> -- The attribute value must end with the
+  #   specified value.
+  # * <tt>name*=value</tt> -- The attribute value must contain the
+  #   specified value.
+  # * <tt>name~=word</tt> -- The attribute value must contain the specified
+  #   word (space separated).
+  # * <tt>name|=word</tt> -- The attribute value must start with specified
+  #   word.
+  #
+  # For example, the following two selectors match the same element:
+  #   #my_id
+  #   [id=my_id]
+  # and so do the following two selectors:
+  #   .my_class
+  #   [class~=my_class]
+  #
+  # === Alternatives, siblings, children
+  #
+  # Complex selectors use a combination of expressions to match elements:
+  # * <tt>expr1 expr2</tt> -- Match any element against the second expression
+  #   if it has some parent element that matches the first expression.
+  # * <tt>expr1 > expr2</tt> -- Match any element against the second expression
+  #   if it is the child of an element that matches the first expression.
+  # * <tt>expr1 + expr2</tt> -- Match any element against the second expression
+  #   if it immediately follows an element that matches the first expression.
+  # * <tt>expr1 ~ expr2</tt> -- Match any element against the second expression
+  #   that comes after an element that matches the first expression.
+  # * <tt>expr1, expr2</tt> -- Match any element against the first expression,
+  #   or against the second expression.
+  #
+  # Since children and sibling selectors may match more than one element given
+  # the first element, the #match method may return more than one match.
+  #
+  # === Pseudo classes
+  #
+  # Pseudo classes were introduced in CSS 3. They are most often used to select
+  # elements in a given position:
+  # * <tt>:root</tt> -- Match the element only if it is the root element
+  #   (no parent element).
+  # * <tt>:empty</tt> -- Match the element only if it has no child elements,
+  #   and no text content.
+  # * <tt>:content(string)</tt> -- Match the element only if it has <tt>string</tt>
+  #   as its text content (ignoring leading and trailing whitespace).
+  # * <tt>:only-child</tt> -- Match the element if it is the only child (element)
+  #   of its parent element.
+  # * <tt>:only-of-type</tt> -- Match the element if it is the only child (element)
+  #   of its parent element and its type.
+  # * <tt>:first-child</tt> -- Match the element if it is the first child (element)
+  #   of its parent element.
+  # * <tt>:first-of-type</tt> -- Match the element if it is the first child (element)
+  #   of its parent element of its type.
+  # * <tt>:last-child</tt> -- Match the element if it is the last child (element)
+  #   of its parent element.
+  # * <tt>:last-of-type</tt> -- Match the element if it is the last child (element)
+  #   of its parent element of its type.
+  # * <tt>:nth-child(b)</tt> -- Match the element if it is the b-th child (element)
+  #   of its parent element. The value <tt>b</tt> specifies its index, starting with 1.
+  # * <tt>:nth-child(an+b)</tt> -- Match the element if it is the b-th child (element)
+  #   in each group of <tt>a</tt> child elements of its parent element.
+  # * <tt>:nth-child(-an+b)</tt> -- Match the element if it is the first child (element)
+  #   in each group of <tt>a</tt> child elements, up to the first <tt>b</tt> child
+  #   elements of its parent element.
+  # * <tt>:nth-child(odd)</tt> -- Match element in the odd position (i.e. first, third).
+  #   Same as <tt>:nth-child(2n+1)</tt>.
+  # * <tt>:nth-child(even)</tt> -- Match element in the even position (i.e. second,
+  #   fourth). Same as <tt>:nth-child(2n+2)</tt>.
+  # * <tt>:nth-of-type(..)</tt> -- As above, but only counts elements of its type.
+  # * <tt>:nth-last-child(..)</tt> -- As above, but counts from the last child.
+  # * <tt>:nth-last-of-type(..)</tt> -- As above, but counts from the last child and
+  #   only elements of its type.
+  # * <tt>:not(selector)</tt> -- Match the element only if the element does not
+  #   match the simple selector.
+  #
+  # As you can see, <tt>:nth-child</tt> pseudo class and its variant can get quite
+  # tricky and the CSS specification doesn't do a much better job explaining it.
+  # But after reading the examples and trying a few combinations, it's easy to
+  # figure out.
+  #
+  # For example:
+  #   table tr:nth-child(odd)
+  # Selects every second row in the table starting with the first one.
+  #
+  #   div p:nth-child(4)
+  # Selects the fourth paragraph in the +div+, but not if the +div+ contains
+  # other elements, since those are also counted.
+  #
+  #   div p:nth-of-type(4)
+  # Selects the fourth paragraph in the +div+, counting only paragraphs, and

+  #
+  # The substitution value may be a string or a regular expression. All other
+  # values are converted to strings.
+  #
+  # For example:
+  #   selector = HTML::Selector.new "#?", /^\d+$/
+  # matches any element whose identifier consists of one or more digits.

content tag already knows which tags are boolean and the values that
should generate them when a truthy value is passed, so leave this logic
for it instead of duplicating when generating options tags.

This fixes potential thread safety issues introduced in 09f6fe1. The problem
with the original code was that the "recursion-stopping" `nil` values could
be seen by other threads.

Subject: Fix `current_page?` when the URL contains escaped characters

In some cases webservers like nginx send the escaped characters
lowercased to the Rails application. The current_page? helper was
comparing the escaped strings that are different since Ruby escapes the
URL using uppercased characters.

Subject: Add "extname" option to javascript_include_tag

ActionView::Helpers.asset_path is where the logic for
javascript_include_tag resides.  It takes an extname option for
specifying the extension or false to not append it.  This exposes that
option to javascript_include_tag.

Without the option files that didn't end with ".js" would get the
extension appended to them.  This broke JST templates and other file
types that should be interpreted as JavaScript but who's file extension
isn't ".js"

+
+module ActionView
+  # Layouts reverse the common pattern of including shared headers and footers in many templates to isolate changes in
+  # repeated setups. The inclusion pattern has pages that look like this:
+  #
+  #   <%= render "shared/header" %>
+  #   Hello World
+  #   <%= render "shared/footer" %>
+  #
+  # This approach is a decent way of keeping common structures isolated from the changing content, but it's verbose
+  # and if you ever want to change the structure of these two includes, you'll have to change all the templates.
+  #
+  # With layouts, you can flip it around and have the common structure know where to insert changing content. This means
+  # that the header and footer are only mentioned in one place, like this:
+  #
+  #   // The header part of this layout
+  #   <%= yield %>
+  #   // The footer part of this layout
+  #
+  # And then you have content pages that look like this:
+  #
+  #    hello world
+  #
+  # At rendering time, the content page is computed and then inserted in the layout, like this:
+  #
+  #   // The header part of this layout
+  #   hello world
+  #   // The footer part of this layout
+  #
+  # == Accessing shared variables
+  #
+  # Layouts have access to variables specified in the content pages and vice versa. This allows you to have layouts with
+  # references that won't materialize before rendering time:
+  #
+  #   <h1><%= @page_title %></h1>
+  #   <%= yield %>
+  #
+  # ...and content pages that fulfill these references _at_ rendering time:
+  #
+  #    <% @page_title = "Welcome" %>
+  #    Off-world colonies offers you a chance to start a new life
+  #
+  # The result after rendering is:
+  #
+  #   <h1>Welcome</h1>
+  #   Off-world colonies offers you a chance to start a new life
+  #
+  # == Layout assignment
+  #
+  # You can either specify a layout declaratively (using the #layout class method) or give
+  # it the same name as your controller, and place it in <tt>app/views/layouts</tt>.
+  # If a subclass does not have a layout specified, it inherits its layout using normal Ruby inheritance.
+  #
+  # For instance, if you have PostsController and a template named <tt>app/views/layouts/posts.html.erb</tt>,
+  # that template will be used for all actions in PostsController and controllers inheriting
+  # from PostsController.
+  #
+  # If you use a module, for instance Weblog::PostsController, you will need a template named
+  # <tt>app/views/layouts/weblog/posts.html.erb</tt>.
+  #
+  # Since all your controllers inherit from ApplicationController, they will use
+  # <tt>app/views/layouts/application.html.erb</tt> if no other layout is specified
+  # or provided.
+  #
+  # == Inheritance Examples
+  #
+  #   class BankController < ActionController::Base
+  #     # bank.html.erb exists
+  #
+  #   class ExchangeController < BankController
+  #     # exchange.html.erb exists
+  #
+  #   class CurrencyController < BankController
+  #
+  #   class InformationController < BankController
+  #     layout "information"
+  #
+  #   class TellerController < InformationController
+  #     # teller.html.erb exists
+  #
+  #   class EmployeeController < InformationController
+  #     # employee.html.erb exists
+  #     layout nil
+  #
+  #   class VaultController < BankController
+  #     layout :access_level_layout
+  #
+  #   class TillController < BankController
+  #     layout false
+  #
+  # In these examples, we have three implicit lookup scenarios:
+  # * The BankController uses the "bank" layout.
+  # * The ExchangeController uses the "exchange" layout.
+  # * The CurrencyController inherits the layout from BankController.
+  #
+  # However, when a layout is explicitly set, the explicitly set layout wins:
+  # * The InformationController uses the "information" layout, explicitly set.
+  # * The TellerController also uses the "information" layout, because the parent explicitly set it.
+  # * The EmployeeController uses the "employee" layout, because it set the layout to nil, resetting the parent configuration.
+  # * The VaultController chooses a layout dynamically by calling the <tt>access_level_layout</tt> method.
+  # * The TillController does not use a layout at all.
+  #
+  # == Types of layouts
+  #
+  # Layouts are basically just regular templates, but the name of this template needs not be specified statically. Sometimes
+  # you want to alternate layouts depending on runtime information, such as whether someone is logged in or not. This can
+  # be done either by specifying a method reference as a symbol or using an inline method (as a proc).
+  #
+  # The method reference is the preferred approach to variable layouts and is used like this:
+  #
+  #   class WeblogController < ActionController::Base
+  #     layout :writers_and_readers
+  #
+  #     def index
+  #       # fetching posts
+  #     end
+  #
+  #     private
+  #       def writers_and_readers
+  #         logged_in? ? "writer_layout" : "reader_layout"
+  #       end
+  #   end
+  #
+  # Now when a new request for the index action is processed, the layout will vary depending on whether the person accessing
+  # is logged in or not.
+  #
+  # If you want to use an inline method, such as a proc, do something like this:
+  #
+  #   class WeblogController < ActionController::Base
+  #     layout proc { |controller| controller.logged_in? ? "writer_layout" : "reader_layout" }
+  #   end
+  #
+  # If an argument isn't given to the proc, it's evaluated in the context of
+  # the current controller anyway.
+  #
+  #   class WeblogController < ActionController::Base
+  #     layout proc { logged_in? ? "writer_layout" : "reader_layout" }
+  #   end
+  #
+  # Of course, the most common way of specifying a layout is still just as a plain template name:
+  #
+  #   class WeblogController < ActionController::Base
+  #     layout "weblog_standard"
+  #   end
+  #
+  # The template will be looked always in <tt>app/views/layouts/</tt> folder. But you can point
+  # <tt>layouts</tt> folder direct also. <tt>layout "layouts/demo"</tt> is the same as <tt>layout "demo"</tt>.
+  #
+  # Setting the layout to nil forces it to be looked up in the filesystem and fallbacks to the parent behavior if none exists.
+  # Setting it to nil is useful to re-enable template lookup overriding a previous configuration set in the parent:
+  #
+  #     class ApplicationController < ActionController::Base
+  #       layout "application"
+  #     end
+  #
+  #     class PostsController < ApplicationController
+  #       # Will use "application" layout
+  #     end
+  #
+  #     class CommentsController < ApplicationController
+  #       # Will search for "comments" layout and fallback "application" layout
+  #       layout nil
+  #     end
+  #
+  # == Conditional layouts
+  #
+  # If you have a layout that by default is applied to all the actions of a controller, you still have the option of rendering
+  # a given action or set of actions without a layout, or restricting a layout to only a single action or a set of actions. The
+  # <tt>:only</tt> and <tt>:except</tt> options can be passed to the layout call. For example:
+  #
+  #   class WeblogController < ActionController::Base
+  #     layout "weblog_standard", except: :rss
+  #
+  #     # ...
+  #
+  #   end
+  #
+  # This will assign "weblog_standard" as the WeblogController's layout for all actions except for the +rss+ action, which will
+  # be rendered directly, without wrapping a layout around the rendered view.
+  #
+  # Both the <tt>:only</tt> and <tt>:except</tt> condition can accept an arbitrary number of method references, so
+  # #<tt>except: [ :rss, :text_only ]</tt> is valid, as is <tt>except: :rss</tt>.
+  #
+  # == Using a different layout in the action render call
+  #
+  # If most of your actions use the same layout, it makes perfect sense to define a controller-wide layout as described above.
+  # Sometimes you'll have exceptions where one action wants to use a different layout than the rest of the controller.
+  # You can do this by passing a <tt>:layout</tt> option to the <tt>render</tt> call. For example:
+  #
+  #   class WeblogController < ActionController::Base
+  #     layout "weblog_standard"
+  #
+  #     def help
+  #       render action: "help", layout: "help"
+  #     end
+  #   end
+  #
+  # This will override the controller-wide "weblog_standard" layout, and will render the help action with the "help" layout instead.

need to submit different attributes.

Subject: Revert "Merge pull request #13027 from akshay-vishnoi/f-refactor"

This reverts commit f4a5a9ea4d183f4102796215d4502c46dbe3e52b, reversing
changes made to 7ccb482181ee6c47c765406009018a15172812de.

Reason:

The logic is different, the first call to #option_value_selected? is for
the :selected option (the argument is the "selected" variable), the second
call is for the :disabled option (the argument is the "disabled" variable).

Subject: Ensure simple_format escapes its html attributes

The previous behavior equated the sanitize option for simple_format with the
escape option of content_tag, however these are two distinct concepts.

This fixes CVE-2013-6416

Subject: Stop using i18n's built in HTML error handling.

i18n doesn't depend on active support which means it can't use our html_safe
code to do its escaping when generating the spans.  Rather than try to sanitize
the output from i18n, just revert to our old behaviour of rescuing the error
and constructing the tag ourselves.

Subject: Action Pack Variants

By default, variants in the templates will be picked up if a variant is set
and there's a match. The format will be:

  app/views/projects/show.html.erb
  app/views/projects/show.html+tablet.erb
  app/views/projects/show.html+phone.erb

If request.variant = :tablet is set, we'll automatically be rendering the
html+tablet template.

In the controller, we can also tailer to the variants with this syntax:

  class ProjectsController < ActionController::Base
    def show
      respond_to do |format|
        format.html do |html|
          @stars = @project.stars

          html.tablet { @notifications = @project.notifications }
          html.phone  { @chat_heads    = @project.chat_heads }
        end

        format.js
        format.atom
      end
    end
  end

The variant itself is nil by default, but can be set in before filters, like
so:

  class ApplicationController < ActionController::Base
    before_action do
      if request.user_agent =~ /iPad/
        request.variant = :tablet
      end
    end
  end

This is modeled loosely on custom mime types, but it's specifically not
intended to be used together. If you're going to make a custom mime type,
you don't need a variant. Variants are for variations on a single mime
types.

Before ec16ba75a5493b9da972eea08bae630eba35b62f,
ActionView::Helpers::TranslationHelper#translate has raised errors with

From: Gaelian Ditchburn <gaelian.ditchburn@gmail.com>
Date: Sun, 3 Jun 2012 19:07:54 +1000
Subject: Switched to use `display:none` in extra_tags_for_form method.

The use of `display:inline` with the content_tag call in the
extra_tags_for_form method potentially causes display issues with some
browsers, namely Internet Explorer. IE's behaviour of not collapsing
the line height on divs with ostensibly no content means that the
automatically added div containing the hidden authenticity_token, utf8
and _method form input tags may interfere with other visible form
elements in certain circumstances. The use of `display:none` rather
than `display:inline` fixes this problem.

Fixes #6403
