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 & 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) - # end - # end - # end - # end - # - # More builder documentation can be found at http://builder.rubyforge.org. - class Base - include Helpers, ::ERB::Util, Context - - # Specify the proc used to decorate input tags that refer to attributes with errors. - cattr_accessor :field_error_proc - @@field_error_proc = Proc.new{ |html_tag, instance| "<div class=\"field_with_errors\">#{html_tag}</div>".html_safe } - - # How to complete the streaming when an exception occurs. - # This is our best guess: first try to close the attribute, then the tag. - cattr_accessor :streaming_completion_on_exception - @@streaming_completion_on_exception = %("><script>window.location = "/500.html"</script></html>) - - # Specify whether rendering within namespaced controllers should prefix - # the partial paths for ActiveModel objects with the namespace. - # (e.g., an Admin::PostsController would render @post using /admin/posts/_post.erb) - cattr_accessor :prefix_partial_path_with_controller_namespace - @@prefix_partial_path_with_controller_namespace = true - - # Specify default_formats that can be rendered. - cattr_accessor :default_formats - - class_attribute :_routes - class_attribute :logger - - class << self - delegate :erb_trim_mode=, :to => 'ActionView::Template::Handlers::ERB' - - def cache_template_loading - ActionView::Resolver.caching?

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.

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]. - module DateHelper - # Reports the approximate distance in time between two Time, Date or DateTime objects or integers as seconds. - # Pass <tt>include_seconds: true</tt> if you want more detailed approximations when distance < 1 min, 29 secs. - # Distances are reported based on the following table: - # - # 0 <-> 29 secs # => less than a minute - # 30 secs <-> 1 min, 29 secs # => 1 minute - # 1 min, 30 secs <-> 44 mins, 29 secs # => [2..44] minutes - # 44 mins, 30 secs <-> 89 mins, 29 secs # => about 1 hour - # 89 mins, 30 secs <-> 23 hrs, 59 mins, 29 secs # => about [2..24] hours - # 23 hrs, 59 mins, 30 secs <-> 41 hrs, 59 mins, 29 secs # => 1 day - # 41 hrs, 59 mins, 30 secs <-> 29 days, 23 hrs, 59 mins, 29 secs # => [2..29] days - # 29 days, 23 hrs, 59 mins, 30 secs <-> 44 days, 23 hrs, 59 mins, 29 secs # => about 1 month - # 44 days, 23 hrs, 59 mins, 30 secs <-> 59 days, 23 hrs, 59 mins, 29 secs # => about 2 months - # 59 days, 23 hrs, 59 mins, 30 secs <-> 1 yr minus 1 sec # => [2..12] months - # 1 yr <-> 1 yr, 3 months # => about 1 year - # 1 yr, 3 months <-> 1 yr, 9 months # => over 1 year - # 1 yr, 9 months <-> 2 yr minus 1 sec # => almost 2 years - # 2 yrs <-> max time or date # => (same rules as 1 yr) - # - # With <tt>include_seconds: true</tt> and the difference < 1 minute 29 seconds: - # 0-4 secs # => less than 5 seconds - # 5-9 secs # => less than 10 seconds - # 10-19 secs # => less than 20 seconds - # 20-39 secs # => half a minute - # 40-59 secs # => less than a minute - # 60-89 secs # => 1 minute - # - # from_time = Time.now - # distance_of_time_in_words(from_time, from_time + 50.minutes) # => about 1 hour - # distance_of_time_in_words(from_time, 50.minutes.from_now) # => about 1 hour - # distance_of_time_in_words(from_time, from_time + 15.seconds) # => less than a minute - # distance_of_time_in_words(from_time, from_time + 15.seconds, include_seconds: true) # => less than 20 seconds - # distance_of_time_in_words(from_time, 3.years.from_now) # => about 3 years - # distance_of_time_in_words(from_time, from_time + 60.hours) # => 3 days - # distance_of_time_in_words(from_time, from_time + 45.seconds, include_seconds: true) # => less than a minute - # distance_of_time_in_words(from_time, from_time - 45.seconds, include_seconds: true) # => less than a minute - # distance_of_time_in_words(from_time, 76.seconds.from_now) # => 1 minute - # distance_of_time_in_words(from_time, from_time + 1.year + 3.days) # => about 1 year - # distance_of_time_in_words(from_time, from_time + 3.years + 6.months) # => over 3 years - # distance_of_time_in_words(from_time, from_time + 4.years + 9.days + 30.minutes + 5.seconds) # => about 4 years - # - # to_time = Time.now + 6.years + 19.days - # distance_of_time_in_words(from_time, to_time, include_seconds: true) # => about 6 years - # distance_of_time_in_words(to_time, from_time, include_seconds: true) # => about 6 years - # distance_of_time_in_words(Time.now, Time.now) # => less than a minute - def distance_of_time_in_words(from_time, to_time = 0, include_seconds_or_options = {}, options = {}) - if include_seconds_or_options.is_a?(Hash) - options = include_seconds_or_options - else - ActiveSupport::Deprecation.warn "distance_of_time_in_words and time_ago_in_words now accept :include_seconds " + - "as a part of options hash, not a boolean argument" - options[:include_seconds] ||= !!include_seconds_or_options - end - - options = { - scope: :'datetime.distance_in_words' - }.merge!(options) - - from_time = from_time.to_time if from_time.respond_to?(:to_time) - to_time = to_time.to_time if to_time.respond_to?(:to_time) - from_time, to_time = to_time, from_time if from_time > to_time - distance_in_minutes = ((to_time - from_time)/60.0).round - distance_in_seconds = (to_time - from_time).round - - I18n.with_options :locale => options[:locale], :scope => options[:scope] do |locale| - case distance_in_minutes - when 0..1 - return distance_in_minutes == 0 ?

# 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 -

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 - object_name = record - object = nil - else - object = record.is_a?(Array) ? record.last : record - raise ArgumentError, "First argument in form cannot contain nil or be empty" unless object - object_name = options[:as] || model_name_from_record_or_class(object).param_key - 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) - html_options[:method] = options.delete(:method) if options.has_key?(:method) - html_options[:authenticity_token] = options.delete(:authenticity_token) - - builder = instantiate_builder(object_name, object, options) - output = capture(builder, &block) - html_options[:multipart] ||= builder.multipart? - - form_tag(options[:url] || {}, html_options) { output } - end - - def apply_form_for_options!(record, object, options) #:nodoc: - object = convert_to_model(object) - - as = options[:as] - action, method = object.respond_to?(:persisted?) && object.persisted? ?

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.

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" /> - # - # # Let's say that @puppy.gooddog is "no": - # check_box("puppy", "gooddog", {}, "yes", "no") - # # => <input name="puppy[gooddog]" type="hidden" value="no" /> - # # <input type="checkbox" id="puppy_gooddog" name="puppy[gooddog]" value="yes" /> - # - # check_box("eula", "accepted", { class: 'eula_check' }, "yes", "no") - # # => <input name="eula[accepted]" type="hidden" value="no" /> - # # <input type="checkbox" class="eula_check" id="eula_accepted" name="eula[accepted]" value="yes" /> - def check_box(object_name, method, options = {}, checked_value = "1", unchecked_value = "0") - Tags::CheckBox.new(object_name, method, self, checked_value, unchecked_value, options).render - end - - # Returns a radio button tag for accessing a specified attribute (identified by +method+) on an object - # assigned to the template (identified by +object+).

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") %> - # I am an adult: <%= f.div_radio_button(:admin, "adult") %> - # <% end -%> - # - # The standard set of helper methods for form building are located in the - # +field_helpers+ class attribute. - class FormBuilder - include ModelNaming - - # The methods which wrap a form helper call. - class_attribute :field_helpers - self.field_helpers = [:fields_for, :label, :text_field, :password_field, - :hidden_field, :file_field, :text_area, :check_box, - :radio_button, :color_field, :search_field, - :telephone_field, :phone_field, :date_field, - :time_field, :datetime_field, :datetime_local_field, - :month_field, :week_field, :url_field, :email_field, - :number_field, :range_field] - - attr_accessor :object_name, :object, :options - - attr_reader :multipart, :index - alias :multipart? :multipart - - def multipart=(multipart) - @multipart = multipart - - if parent_builder = @options[:parent_builder] - parent_builder.multipart = multipart - end - end - - def self._to_partial_path - @_to_partial_path ||= name.demodulize.underscore.sub!(/_builder$/, '') - end - - def to_partial_path - self.class._to_partial_path - end - - def to_model - self - end - - def initialize(object_name, object, template, options, block=nil) - if block - ActiveSupport::Deprecation.warn "Giving a block to FormBuilder is deprecated and has no effect anymore." - end - - @nested_child_index = {} - @object_name, @object, @template, @options = object_name, object, template, options - @default_options = @options ? @options.slice(:index, :namespace) : {} - if @object_name.to_s.match(/\[\]$/) - if object ||= @template.instance_variable_get("@#{Regexp.last_match.pre_match}") and object.respond_to?(:to_param) - @auto_index = object.to_param - else - raise ArgumentError, "object[] naming but object param and @object var don't exist or don't respond to to_param: #{object.inspect}" - end - end - @multipart = nil - @index = options[:index] || options[:child_index] - end - - (field_helpers - [:label, :check_box, :radio_button, :fields_for, :hidden_field, :file_field]).each do |selector| - class_eval <<-RUBY_EVAL, __FILE__, __LINE__ + 1 - def #{selector}(method, options = {}) # def text_field(method, options = {}) - @template.send( # @template.send( - #{selector.inspect}, # "text_field", - @object_name, # @object_name, - method, # method, - objectify_options(options)) # objectify_options(options)) - end # end - RUBY_EVAL - end - - # 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 %> - # - # <%= 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.

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" /> - # - # # Let's say that @puppy.gooddog is "no": - # check_box("puppy", "gooddog", {}, "yes", "no") - # # => <input name="puppy[gooddog]" type="hidden" value="no" /> - # # <input type="checkbox" id="puppy_gooddog" name="puppy[gooddog]" value="yes" /> - # - # check_box("eula", "accepted", { class: 'eula_check' }, "yes", "no") - # # => <input name="eula[accepted]" type="hidden" value="no" /> - # # <input type="checkbox" class="eula_check" id="eula_accepted" name="eula[accepted]" value="yes" /> - def check_box(method, options = {}, checked_value = "1", unchecked_value = "0") - @template.check_box(@object_name, method, objectify_options(options), checked_value, unchecked_value) - end - - # Returns a radio button tag for accessing a specified attribute (identified by +method+) on an object - # assigned to the template (identified by +object+).

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.
