It's a way to - # redirect incoming requests to controllers and actions. This replaces - # mod_rewrite rules. Best of all, Rails' Routing works with any web server. - # Routes are defined in <tt>config/routes.rb</tt>. - # - # Consider the following route, installed by Rails when you generate your - # application: - # - # map.connect ':controller/:action/:id' - # - # This route states that it expects requests to consist of a - # <tt>:controller</tt> followed by an <tt>:action</tt> that in turn is fed - # some <tt>:id</tt>. - # - # Suppose you get an incoming request for <tt>/blog/edit/22</tt>, you'll end up - # with: - # - # params = { :controller => 'blog', - # :action => 'edit', - # :id => '22' - # } - # - # Think of creating routes as drawing a map for your requests. The map tells - # them where to go based on some predefined pattern: - # - # ActionController::Routing::Routes.draw do |map| - # Pattern 1 tells some request to go to one place - # Pattern 2 tell them to go to another - # ... - # end - # - # The following symbols are special: - # - # :controller maps to your controller name - # :action maps to an action with your controllers - # - # Other names simply map to a parameter as in the case of <tt>:id</tt>. - # - # == Route priority - # - # Not all routes are created equally. Routes have priority defined by the - # order of appearance of the routes in the <tt>config/routes.rb</tt> file. The priority goes - # from top to bottom. The last route in that file is at the lowest priority - # and will be applied last. If no route matches, 404 is returned. - # - # Within blocks, the empty pattern is at the highest priority. - # In practice this works out nicely: - # - # ActionController::Routing::Routes.draw do |map| - # map.with_options :controller => 'blog' do |blog| - # blog.show '', :action => 'list' - # end - # map.connect ':controller/:action/:view' - # end - # - # In this case, invoking blog controller (with an URL like '/blog/') - # without parameters will activate the 'list' action by default. - # - # == Defaults routes and default parameters - # - # Setting a default route is straightforward in Rails - you simply append a - # Hash at the end of your mapping to set any default parameters. - # - # Example: - # - # ActionController::Routing:Routes.draw do |map| - # map.connect ':controller/:action/:id', :controller => 'blog' - # end - # - # This sets up +blog+ as the default controller if no other is specified. - # This means visiting '/' would invoke the blog controller. - # - # More formally, you can include arbitrary parameters in the route, thus: - # - # map.connect ':controller/:action/:id', :action => 'show', :page => 'Dashboard' - # - # This will pass the :page parameter to all incoming requests that match this route. - # - # Note: The default routes, as provided by the Rails generator, make all actions in every - # controller accessible via GET requests. You should consider removing them or commenting - # them out if you're using named routes and resources. - # - # == Named routes - # - # Routes can be named with the syntax <tt>map.name_of_route options</tt>, - # allowing for easy reference within your source as +name_of_route_url+ - # for the full URL and +name_of_route_path+ for the URI path. - # - # Example: - # - # # In routes.rb - # map.login 'login', :controller => 'accounts', :action => 'login' - # - # # With render, redirect_to, tests, etc. - # redirect_to login_url - # - # Arguments can be passed as well. - # - # redirect_to show_item_path(:id => 25) - # - # Use <tt>map.root</tt> as a shorthand to name a route for the root path "". - # - # # In routes.rb - # map.root :controller => 'blogs' - # - # # would recognize http://www.example.com/ as - # params = { :controller => 'blogs', :action => 'index' } - # - # # and provide these named routes - # root_url # => 'http://www.example.com/' - # root_path # => '' - # - # You can also specify an already-defined named route in your <tt>map.root</tt> call: - # - # # In routes.rb - # map.new_session :controller => 'sessions', :action => 'new' - # map.root :new_session - # - # Note: when using +with_options+, the route is simply named after the - # method you call on the block parameter rather than map. - # - # # In routes.rb - # map.with_options :controller => 'blog' do |blog| - # blog.show '', :action => 'list' - # blog.delete 'delete/:id', :action => 'delete' - # blog.edit 'edit/:id', :action => 'edit' - # end - # - # # provides named routes for show, delete, and edit - # link_to @article.title, show_path(:id => @article.id) - # - # == Pretty URLs - # - # Routes can generate pretty URLs.

The - # match will always use the default encoding or ASCII. - # - # == Route globbing - # - # Specifying <tt>*[string]</tt> as part of a rule like: - # - # map.connect '*path' , :controller => 'blog' , :action => 'unrecognized?' - # - # will glob all remaining parts of the route that were not recognized earlier. - # The globbed values are in <tt>params[:path]</tt> as an array of path segments. - # - # == Route conditions - # - # With conditions you can define restrictions on routes. Currently the only valid condition is <tt>:method</tt>. - # - # * <tt>:method</tt> - Allows you to specify which method can access the route. Possible values are <tt>:post</tt>, - # <tt>:get</tt>, <tt>:put</tt>, <tt>:delete</tt> and <tt>:any</tt>. The default value is <tt>:any</tt>, - # <tt>:any</tt> means that any method can access the route. - # - # Example: - # - # map.connect 'post/:id', :controller => 'posts', :action => 'show', - # :conditions => { :method => :get } - # map.connect 'post/:id', :controller => 'posts', :action => 'create_comment', - # :conditions => { :method => :post } - # - # Now, if you POST to <tt>/posts/:id</tt>, it will route to the <tt>create_comment</tt> action. A GET on the same - # URL will route to the <tt>show</tt> action. - # - # == Reloading routes - # - # You can reload routes if you feel you must: - # - # ActionController::Routing::Routes.reload - # - # This will clear all named routes and reload routes.rb if the file has been modified from - # last load.

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. - def resources(*entities, &block) - options = entities.extract_options! - entities.each { |entity| map_resource(entity, options.dup, &block) } - end - - # Creates named routes for implementing verb-oriented controllers for a singleton \resource. - # A singleton \resource is global to its current context.
