module Routing
# Mapper instances are used to build routes. The object passed to the draw
# block in config/routes.rb is a Mapper instance.
#
# Mapper instances have relatively few instance methods, in order to avoid
# clashes with named routes.
#
# == Overview
#
# ActionController::Resources are a way of defining RESTful \resources. A RESTful \resource, in basic terms,
# is something that can be pointed at and it will respond with a representation of the data requested.
# In real terms this could mean a user with a browser requests an HTML page, or that a desktop application
# requests XML data.
#
# RESTful design is based on the assumption that there are four generic verbs that a user of an
# application can request from a \resource (the noun).
#
# \Resources can be requested using four basic HTTP verbs (GET, POST, PUT, DELETE), the method used
# denotes the type of action that should take place.
#
# === The Different Methods and their Usage
#
# * GET - Requests for a \resource, no saving or editing of a \resource should occur in a GET request.
# * POST - Creation of \resources.
# * PUT - Editing of attributes on a \resource.
# * DELETE - Deletion of a \resource.
#
# === Examples
#
# # A GET request on the Posts resource is asking for all Posts
# GET /posts
#
# # A GET request on a single Post resource is asking for that particular Post
# GET /posts/1
#
# # A POST request on the Posts resource is asking for a Post to be created with the supplied details
# POST /posts # with => { :post => { :title => "My Whizzy New Post", :body => "I've got a brand new combine harvester" } }
#
# # A PUT request on a single Post resource is asking for a Post to be updated
# PUT /posts # with => { :id => 1, :post => { :title => "Changed Whizzy Title" } }
#
# # A DELETE request on a single Post resource is asking for it to be deleted
# DELETE /posts # with => { :id => 1 }
#
# By using the REST convention, users of our application can assume certain things about how the data
# is requested and how it is returned. Rails simplifies the routing part of RESTful design by
# supplying you with methods to create them in your routes.rb file.

# Creates named routes for implementing verb-oriented controllers

#
# class MessagesController < ActionController::Base
# # GET messages_url
# def index
# # return all messages

# # return an HTML form for describing a new message

# def show
# # find and return a specific message

# def edit
# # return an HTML form for editing a specific message
# end
#
# # PUT message_url(:id => 1)
# def update
# # find and update a specific message
# end
#
# # DELETE message_url(:id => 1)
# def destroy
# # delete a specific message
# end
# end
#
# Along with the routes themselves, +resources+ generates named routes for use in
# controllers and views. <tt>map.resources :messages</tt> produces the following named routes and helpers:
#
# Named Route Helpers
# ============ =====================================================
# messages messages_url, hash_for_messages_url,
# messages_path, hash_for_messages_path
#
# message message_url(id), hash_for_message_url(id),
# message_path(id), hash_for_message_path(id)
#
# new_message new_message_url, hash_for_new_message_url,
# new_message_path, hash_for_new_message_path
#
# edit_message edit_message_url(id), hash_for_edit_message_url(id),
# edit_message_path(id), hash_for_edit_message_path(id)
#
# You can use these helpers instead of +url_for+ or methods that take +url_for+ parameters. For example:
#
# redirect_to :controller => 'messages', :action => 'index'
# # and
# <%= link_to "edit this message", :controller => 'messages', :action => 'edit', :id => @message.id %>
#
# now become:
#
# redirect_to messages_url
# # and
# <%= link_to "edit this message", edit_message_url(@message) # calls @message.id automatically
#
# Since web browsers don't support the PUT and DELETE verbs, you will need to add a parameter '_method' to your
# form tags. The form helpers make this a little easier. For an update form with a <tt>@message</tt> object:
#
# <%= form_tag message_path(@message), :method => :put %>
#
# or
#
# <% form_for :message, @message, :url => message_path(@message), :html => {:method => :put} do |f| %>
#
# or
#
# <% form_for @message do |f| %>
#
# which takes into account whether <tt>@message</tt> is a new record or not and generates the
# path and method accordingly.
#
# The +resources+ method accepts the following options to customize the resulting routes:
# * <tt>:collection</tt> - Add named routes for other actions that operate on the collection.
# Takes a hash of <tt>#{action} => #{method}</tt>, where method is <tt>:get</tt>/<tt>:post</tt>/<tt>:put</tt>/<tt>:delete</tt>,
# an array of any of the previous, or <tt>:any</tt> if the method does not matter.
# These routes map to a URL like /messages/rss, with a route of +rss_messages_url+.
# * <tt>:member</tt> - Same as <tt>:collection</tt>, but for actions that operate on a specific member.
# * <tt>:new</tt> - Same as <tt>:collection</tt>, but for actions that operate on the new \resource action.
# * <tt>:controller</tt> - Specify the controller name for the routes.
# * <tt>:singular</tt> - Specify the singular name used in the member routes.
# * <tt>:requirements</tt> - Set custom routing parameter requirements; this is a hash of either
# regular expressions (which must match for the route to match) or extra parameters. For example:
#
# map.resource :profile, :path_prefix => ':name', :requirements => { :name => /[a-zA-Z]+/, :extra => 'value' }
#
# will only match if the first part is alphabetic, and will pass the parameter :extra to the controller.
# * <tt>:conditions</tt> - Specify custom routing recognition conditions. \Resources sets the <tt>:method</tt> value for the method-specific routes.
# * <tt>:as</tt> - Specify a different \resource name to use in the URL path. For example:
# # products_path == '/productos'
# map.resources :products, :as => 'productos' do |product|
# # product_reviews_path(product) == '/productos/1234/comentarios'
# product.resources :product_reviews, :as => 'comentarios'
# end
#
# * <tt>:has_one</tt> - Specify nested \resources, this is a shorthand for mapping singleton \resources beneath the current.
# * <tt>:has_many</tt> - Same has <tt>:has_one</tt>, but for plural \resources.
#
# You may directly specify the routing association with +has_one+ and +has_many+ like:
#
# map.resources :notes, :has_one => :author, :has_many => [:comments, :attachments]
#
# This is the same as:
#
# map.resources :notes do |notes|
# notes.resource :author
# notes.resources :comments
# notes.resources :attachments
# end
#
# * <tt>:path_names</tt> - Specify different path names for the actions. For example:
# # new_products_path == '/productos/nuevo'
# # bids_product_path(1) == '/productos/1/licitacoes'
# map.resources :products, :as => 'productos', :member => { :bids => :get }, :path_names => { :new => 'nuevo', :bids => 'licitacoes' }
#
# You can also set default action names from an environment, like this:
# config.action_controller.resources_path_names = { :new => 'nuevo', :edit => 'editar' }
#
# * <tt>:path_prefix</tt> - Set a prefix to the routes with required route variables.
#
# Weblog comments usually belong to a post, so you might use +resources+ like:
#
# map.resources :articles
# map.resources :comments, :path_prefix => '/articles/:article_id'
#
# You can nest +resources+ calls to set this automatically:
#
# map.resources :articles do |article|
# article.resources :comments
# end
#
# The comment \resources work the same, but must now include a value for <tt>:article_id</tt>.
#
# article_comments_url(@article)
# article_comment_url(@article, @comment)
#
# article_comments_url(:article_id => @article)
# article_comment_url(:article_id => @article, :id => @comment)
#
# If you don't want to load all objects from the database you might want to use the <tt>article_id</tt> directly:
#
# articles_comments_url(@comment.article_id, @comment)
#
# * <tt>:name_prefix</tt> - Define a prefix for all generated routes, usually ending in an underscore.
# Use this if you have named routes that may clash.
#
# map.resources :tags, :path_prefix => '/books/:book_id', :name_prefix => 'book_'
# map.resources :tags, :path_prefix => '/toys/:toy_id', :name_prefix => 'toy_'
#
# You may also use <tt>:name_prefix</tt> to override the generic named routes in a nested \resource:
#
# map.resources :articles do |article|
# article.resources :comments, :name_prefix => nil
# end
#
# This will yield named \resources like so:
#
# comments_url(@article)
# comment_url(@article, @comment)
#
# * <tt>:shallow</tt> - If true, paths for nested resources which reference a specific member
# (ie. those with an :id parameter) will not use the parent path prefix or name prefix.
#
# The <tt>:shallow</tt> option is inherited by any nested resource(s).
#
# For example, 'users', 'posts' and 'comments' all use shallow paths with the following nested resources:
#
# map.resources :users, :shallow => true do |user|
# user.resources :posts do |post|
# post.resources :comments
# end
# end
# # --> GET /users/1/posts (maps to the PostsController#index action as usual)
# # also adds the usual named route called "user_posts"
# # --> GET /posts/2 (maps to the PostsController#show action as if it were not nested)
# # also adds the named route called "post"
# # --> GET /posts/2/comments (maps to the CommentsController#index action)
# # also adds the named route called "post_comments"
# # --> GET /comments/2 (maps to the CommentsController#show action as if it were not nested)
# # also adds the named route called "comment"
#
# You may also use <tt>:shallow</tt> in combination with the +has_one+ and +has_many+ shorthand notations like:
#
# map.resources :users, :has_many => { :posts => :comments }, :shallow => true
#
# * <tt>:only</tt> and <tt>:except</tt> - Specify which of the seven default actions should be routed to.
#
# <tt>:only</tt> and <tt>:except</tt> may be set to <tt>:all</tt>, <tt>:none</tt>, an action name or a
# list of action names. By default, routes are generated for all seven actions.
#
# For example:
#
# map.resources :posts, :only => [:index, :show] do |post|
# post.resources :comments, :except => [:update, :destroy]
# end
# # --> GET /posts (maps to the PostsController#index action)
# # --> POST /posts (fails)
# # --> GET /posts/1 (maps to the PostsController#show action)
# # --> DELETE /posts/1 (fails)
# # --> POST /posts/1/comments (maps to the CommentsController#create action)
# # --> PUT /posts/1/comments/1 (fails)
#
# If <tt>map.resources</tt> is called with multiple resources, they all get the same options applied.
#
# Examples:
#
# map.resources :messages, :path_prefix => "/thread/:thread_id"
# # --> GET /thread/7/messages/1
#
# map.resources :messages, :collection => { :rss => :get }
# # --> GET /messages/rss (maps to the #rss action)
# # also adds a named route called "rss_messages"
#
# map.resources :messages, :member => { :mark => :post }
# # --> POST /messages/1/mark (maps to the #mark action)
# # also adds a named route called "mark_message"
#
# map.resources :messages, :new => { :preview => :post }
# # --> POST /messages/new/preview (maps to the #preview action)
# # also adds a named route called "preview_new_message"
#
# map.resources :messages, :new => { :new => :any, :preview => :post }
# # --> POST /messages/new/preview (maps to the #preview action)
# # also adds a named route called "preview_new_message"
# # --> /messages/new can be invoked via any request method
#
# map.resources :messages, :controller => "categories",
# :path_prefix => "/category/:category_id",
# :name_prefix => "category_"
# # --> GET /categories/7/messages/1
# # has named route "category_message"
#
# The +resources+ method sets HTTP method restrictions on the routes it generates. For example, making an
# HTTP POST on <tt>new_message_url</tt> will raise a RoutingError exception. The default route in
# <tt>config/routes.rb</tt> overrides this and allows invalid HTTP methods for \resource routes.

# Creates named routes for implementing verb-oriented controllers for a singleton \resource.
# A singleton \resource is global to its current context. For unnested singleton \resources,
# the \resource is global to the current user visiting the application, such as a user's
# <tt>/account</tt> profile. For nested singleton \resources, the \resource is global to its parent
# \resource, such as a <tt>projects</tt> \resource that <tt>has_one :project_manager</tt>.
# The <tt>project_manager</tt> should be mapped as a singleton \resource under <tt>projects</tt>:
#
# map.resources :projects do |project|
# project.resource :project_manager
# end
#
# See +resources+ for general conventions. These are the main differences:
# * A singular name is given to <tt>map.resource</tt>. The default controller name is still taken from the plural name.
# * To specify a custom plural name, use the <tt>:plural</tt> option. There is no <tt>:singular</tt> option.
# * No default index route is created for the singleton \resource controller.
# * When nesting singleton \resources, only the singular name is used as the path prefix (example: 'account/messages/1')
#
# For example:
#
# map.resource :account
#
# maps these actions in the Accounts controller:
#
# class AccountsController < ActionController::Base
# # GET new_account_url
# def new
# # return an HTML form for describing the new account
# end
#
# # POST account_url
# def create
# # create an account
# end
#
# # GET account_url
# def show
# # find and return the account
# end
#
# # GET edit_account_url
# def edit
# # return an HTML form for editing the account
# end
#
# # PUT account_url
# def update
# # find and update the account
# end
#
# # DELETE account_url
# def destroy
# # delete the account
# end
# end
#
