module Helpers
# Form helpers are designed to make working with models much easier than just standard html elements by
# providing a set of methods for creating forms based on your models. This helper generates the HTML for forms,
# providing a method for each sort of input (e.g., text, password, select, and so on). When the form is
# submitted (i.e., when the user hits the submit button or <tt>form.submit</tt> is called via JavaScript), the form
# inputs will be bundled into the <tt>params</tt> object and passed back to the controller.
#
# There are two types of form helpers: those that specifically work with model attributes and those that don't.
# This helper deals with those that work with model attributes; to see an example of form helpers that don't work
# with model attributes, check the ActionView::Helpers::FormTagHelper documentation.
#
# The core method of this helper, form_for, gives you the ability to create a form for a model instance;
# for example, let's say that you have a model <tt>Person</tt> and want to create a new instance of it:
#
# # Note: a @person variable will have been created in the controller.
# # For example: @person = Person.new
# <% form_for :person, @person, :url => { :action => "create" } do |f| %>
# <%= f.text_field :first_name %>
# <%= f.text_field :last_name %>
# <%= submit_tag 'Create' %>
# <% end %>
#
# The HTML generated for this would be:
#
# <form action="/persons/create" method="post">
# <input id="person_first_name" name="person[first_name]" size="30" type="text" />
# <input id="person_last_name" name="person[last_name]" size="30" type="text" />
# <input name="commit" type="submit" value="Create" />
# </form>
#
# The <tt>params</tt> object created when this form is submitted would look like:
#
# {"action"=>"create", "controller"=>"persons", "person"=>{"first_name"=>"William", "last_name"=>"Smith"}}
#
# The params hash has a nested <tt>person</tt> value, which can therefore be accessed with <tt>params[:person]</tt> in the controller.
# If were editing/updating an instance (e.g., <tt>Person.find(1)</tt> rather than <tt>Person.new</tt> in the controller), the objects
# attribute values are filled into the form (e.g., the <tt>person_first_name</tt> field would have that person's first name in it).
#
# If the object name contains square brackets the id for the object will be inserted. For example:
#
# <%= text_field "person[]", "name" %>
#
# ...will generate the following ERb.
#
# <input type="text" id="person_<%= @person.id %>_name" name="person[<%= @person.id %>][name]" value="<%= @person.name %>" />
#
# If the helper is being used to generate a repetitive sequence of similar form elements, for example in a partial
# used by <tt>render_collection_of_partials</tt>, the <tt>index</tt> option may come in handy. Example:
#
# <%= text_field "person", "name", "index" => 1 %>
#
# ...becomes...
#
# <input type="text" id="person_1_name" name="person[1][name]" value="<%= @person.name %>" />
#
# There are also methods for helping to build form tags in link:classes/ActionView/Helpers/FormOptionsHelper.html,
# link:classes/ActionView/Helpers/DateHelper.html, and link:classes/ActionView/Helpers/ActiveRecordHelper.html
module FormHelper
# Creates a form and a scope around a specific model object that is used as a base for questioning about
# values for the fields.
#
# <% form_for :person, @person, :url => { :action => "update" } do |f| %>
# First name: <%= f.text_field :first_name %>
# Last name : <%= f.text_field :last_name %>
# Biography : <%= f.text_area :biography %>
# Admin? : <%= f.check_box :admin %>
# <% end %>
#
# Worth noting is that the form_for tag is called in a ERb evaluation block, not an ERb output block. So that's <tt><% %></tt>,
# not <tt><%= %></tt>. Also worth noting is that form_for yields a <tt>form_builder</tt> object, in this example as <tt>f</tt>, which emulates
# the API for the stand-alone FormHelper methods, but without the object name. So instead of <tt>text_field :person, :name</tt>,
# you get away with <tt>f.text_field :name</tt>.
#
# Even further, the form_for method allows you to more easily escape the instance variable convention. So while the stand-alone
# approach would require <tt>text_field :person, :name, :object => person</tt>
# to work with local variables instead of instance ones, the form_for calls remain the same. You simply declare once with
# <tt>:person, person</tt> and all subsequent field calls save <tt>:person</tt> and <tt>:object => person</tt>.
#
# 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, @person, :url => { :action => "update" } 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]", @person.company.admin? %>
# <% end %>
#
# 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.
#
# HTML attributes for the form tag can be given as :html => {...}. For example:
#
# <% form_for :person, @person, :html => {:id => 'person_form'} do |f| %>
# ...
# <% end %>
#
# The above form will then have the <tt>id</tt> attribute with the value </tt>person_form</tt>, which you can then
# style with CSS or manipulate with JavaScript.
#
# 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, @person, :url => { :action => "update" }, :builder => LabellingFormBuilder do |f| %>
# <%= f.text_field :first_name %>
# <%= f.text_field :last_name %>
# <%= text_area :person, :biography %>
# <%= check_box_tag "person[admin]", @person.company.admin? %>
# <% end %>
#
# 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(name, object, options, &proc)
# form_for(name, object, options.merge(:builder => LabellingFormBuiler), &proc)
# end
#
# If you don't need to attach a form to a model instance, then check out FormTagHelper#form_tag.
def form_for(object_name, *args, &proc)
raise ArgumentError, "Missing block" unless block_given?
options = args.last.is_a?(Hash) ? args.pop : {}
concat(form_tag(options.delete(:url) || {}, options.delete(:html) || {}), proc.binding)
fields_for(object_name, *(args << options), &proc)
concat('</form>', proc.binding)
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:
#
# ==== Examples
# <% form_for :person, @person, :url => { :action => "update" } 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 %>
# <% end %>
#
# 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.

# Returns a radio button tag for accessing a specified attribute (identified by +method+) on an object

# ==== Examples
# # Let's say that @post.category returns "rails":
