module ActionController
# Polymorphic URL helpers are methods for smart resolution to a named route call when
# given an Active Record model instance. They are to be used in combination with
# ActionController::Resources.
#
# These methods are useful when you want to generate correct URL or path to a RESTful
# resource without having to know the exact type of the record in question.
#
# Nested resources and/or namespaces are also supported, as illustrated in the example:
#
# polymorphic_url([:admin, @article, @comment])
#
# results in:
#
# admin_article_comment_url(@article, @comment)
#
# == Usage within the framework
#
# Polymorphic URL helpers are used in a number of places throughout the Rails framework:
#
# * <tt>url_for</tt>, so you can use it with a record as the argument, e.g.
# <tt>url_for(@article)</tt>;
# * ActionView::Helpers::FormHelper uses <tt>polymorphic_path</tt>, so you can write
# <tt>form_for(@article)</tt> without having to specify <tt>:url</tt> parameter for the form
# action;
# * <tt>redirect_to</tt> (which, in fact, uses <tt>url_for</tt>) so you can write
# <tt>redirect_to(post)</tt> in your controllers;
# * ActionView::Helpers::AtomFeedHelper, so you don't have to explicitly specify URLs
# for feed entries.
#
# == Prefixed polymorphic helpers
#
# In addition to <tt>polymorphic_url</tt> and <tt>polymorphic_path</tt> methods, a
# number of prefixed helpers are available as a shorthand to <tt>:action => "..."</tt>
# in options. Those are:
#
# * <tt>edit_polymorphic_url</tt>, <tt>edit_polymorphic_path</tt>
# * <tt>new_polymorphic_url</tt>, <tt>new_polymorphic_path</tt>
#
# Example usage:
#
# edit_polymorphic_path(@post) # => "/posts/1/edit"
# polymorphic_path(@post, :format => :pdf) # => "/posts/1.pdf"
module PolymorphicRoutes
# Constructs a call to a named RESTful route for the given record and returns the
# resulting URL string. For example:
#
# # calls post_url(post)
# polymorphic_url(post) # => "http://example.com/posts/1"
# polymorphic_url([blog, post]) # => "http://example.com/blogs/1/posts/1"
# polymorphic_url([:admin, blog, post]) # => "http://example.com/admin/blogs/1/posts/1"
# polymorphic_url([user, :blog, post]) # => "http://example.com/users/1/blog/posts/1"
# polymorphic_url(Comment) # => "http://example.com/comments"
#
# ==== Options
#
# * <tt>:action</tt> - Specifies the action prefix for the named route:
# <tt>:new</tt> or <tt>:edit</tt>. Default is no prefix.
# * <tt>:routing_type</tt> - Allowed values are <tt>:path</tt> or <tt>:url</tt>.
# Default is <tt>:url</tt>.
#
# ==== Examples
#
# # an Article record
# polymorphic_url(record) # same as article_url(record)
#
# # a Comment record
# polymorphic_url(record) # same as comment_url(record)
#
# # it recognizes new records and maps to the collection
# record = Comment.new
# polymorphic_url(record) # same as comments_url()
#
# # the class of a record will also map to the collection
# polymorphic_url(Comment) # same as comments_url()
