Allow you to add authentication request from the router. Takes an optional scope and block to provide constraints on the model instance itself.
authenticate do resources :post end authenticate(:admin) do resources :users end authenticate :user, lambda {|u| u.role == "admin"} do root :to => "admin/dashboard#show" end
# File lib/devise/rails/routes.rb, line 256 def authenticate(scope=nil, block=nil) constraint = lambda do |request| request.env["warden"].authenticate!(:scope => scope) && (block.nil? || block.call(request.env["warden"].user(scope))) end constraints(constraint) do yield end end
Allow you to route based on whether a scope is authenticated. You can optionally specify which scope and a block. The block accepts a model and allows extra constraints to be done on the instance.
authenticated :admin do root :to => 'admin/dashboard#show' end authenticated do root :to => 'dashboard#show' end authenticated :user, lambda {|u| u.role == "admin"} do root :to => "admin/dashboard#show" end root :to => 'landing#show'
# File lib/devise/rails/routes.rb, line 284 def authenticated(scope=nil, block=nil) constraint = lambda do |request| request.env["warden"].authenticate?(:scope => scope) && (block.nil? || block.call(request.env["warden"].user(scope))) end constraints(constraint) do yield end end
Includes #devise_for method for routes. This method is responsible to generate all needed routes for devise, based on what modules you have defined in your model.
Let’s say you have an User model configured to use authenticatable, confirmable and recoverable modules. After creating this inside your routes:
devise_for :users
This method is going to look inside your User model and create the needed routes:
# Session routes for Authenticatable (default) new_user_session GET %rusers/ign_in {:controller=>"devise/sessions", :action=>"new"} user_session POST %rusers/ign_in {:controller=>"devise/sessions", :action=>"create"} destroy_user_session GET %rusers/ign_out {:controller=>"devise/sessions", :action=>"destroy"} # Password routes for Recoverable, if User model has :recoverable configured new_user_password GET %rusers/password/new(.:format) {:controller=>"devise/passwords", :action=>"new"} edit_user_password GET %rusers/password/edit(.:format) {:controller=>"devise/passwords", :action=>"edit"} user_password PUT %rusers/password(.:format) {:controller=>"devise/passwords", :action=>"update"} POST %rusers/password(.:format) {:controller=>"devise/passwords", :action=>"create"} # Confirmation routes for Confirmable, if User model has :confirmable configured new_user_confirmation GET %rusers/confirmation/new(.:format) {:controller=>"devise/confirmations", :action=>"new"} user_confirmation GET %rusers/confirmation(.:format) {:controller=>"devise/confirmations", :action=>"show"} POST %rusers/confirmation(.:format) {:controller=>"devise/confirmations", :action=>"create"}
You can configure your routes with some options:
* :class_name => setup a different class to be looked up by devise, if it cannot be properly found by the route name. devise_for :users, :class_name => 'Account' * :path => allows you to setup path name that will be used, as rails routes does. The following route configuration would setup your route as %raccounts instead of /sers: devise_for :users, :path => 'accounts' * :singular => setup the singular name for the given resource. This is used as the instance variable name in controller, as the name in routes and the scope given to warden. devise_for :users, :singular => :user * :path_names => configure different path names to overwrite defaults :sign_in, :sign_out, :sign_up, :password, :confirmation, :unlock. devise_for :users, :path_names => { :sign_in => 'login', :sign_out => 'logout', :password => 'secret', :confirmation => 'verification' } * :controllers => the controller which should be used. All routes by default points to Devise controllers. However, if you want them to point to custom controller, you should do: devise_for :users, :controllers => { :sessions => "users/sessions" } * :failure_app => a rack app which is invoked whenever there is a failure. Strings representing a given are also allowed as parameter. * :sign_out_via => the HTTP method(s) accepted for the :sign_out action (default: :get), if you wish to restrict this to accept only :post or :delete requests you should do: devise_for :users, :sign_out_via => [ :post, :delete ] You need to make sure that your sign_out controls trigger a request with a matching HTTP method. * :module => the namespace to find controllers (default: "devise", thus accessing devise/sessions, devise/registrations, and so on). If you want to namespace all at once, use module: devise_for :users, :module => "users" Notice that whenever you use namespace in the router DSL, it automatically sets the module. So the following setup: namespace :publisher do devise_for :account end Will use publisher/sessions controller instead of devise/sessions controller. You can revert this by providing the :module option to devise_for. Also pay attention that when you use a namespace it will affect all the helpers and methods for controllers and views. For example, using the above setup you'll end with following methods: current_publisher_account, authenticate_publisher_account!, publisher_account_signed_in, etc. * :skip => tell which controller you want to skip routes from being created: devise_for :users, :skip => :sessions * :only => the opposite of :skip, tell which controllers only to generate routes to: devise_for :users, :only => :sessions * :skip_helpers => skip generating Devise url helpers like new_session_path(@user). This is useful to avoid conflicts with previous routes and is false by default. It accepts true as option, meaning it will skip all the helpers for the controllers given in :skip but it also accepts specific helpers to be skipped: devise_for :users, :skip => [:registrations, :confirmations], :skip_helpers => true devise_for :users, :skip_helpers => [:registrations, :confirmations] * :format => include "(.:format)" in the generated routes? true by default, set to false to disable: devise_for :users, :format => false * :constraints => works the same as Rails' constraints * :defaults => works the same as Rails' defaults
Following Rails 3 routes DSL, you can nest #devise_for calls inside a scope:
scope "/my" do devise_for :users end
However, since Devise uses the request path to retrieve the current user, this has one caveat: If you are using a dynamic segment, like so …
scope ":locale" do devise_for :users end
you are required to configure default_url_options in your ApplicationController class, so Devise can pick it:
class ApplicationController < ActionController::Base def self.default_url_options { :locale => I18n.locale } end end
You can pass a block to #devise_for that will add any routes defined in the block to Devise’s list of known actions. This is important if you add a custom action to a controller that overrides an out of the box Devise controller. For example:
class RegistrationsController < Devise::RegistrationsController def update # do something different here end def deactivate # not a standard action # deactivate code here end end
In order to get Devise to recognize the deactivate action, your #devise_for entry should look like this,
devise_scope :owner do post "deactivate", :to => "registrations#deactivate", :as => "deactivate_registration" end

Sets the devise scope to be used in the controller. If you have custom routes, you are required to call this method (also aliased as :as) in order to specify to which controller it is targetted.
as :user do get "sign_in", :to => "devise/sessions#new" end
Notice you cannot have two scopes mapping to the same URL. And remember, if you try to access a devise controller without specifying a scope, it will raise ActionNotFound error.
Also be aware of that ‘#devise_scope’ and ‘as’ use the singular form of the noun where other devise route commands expect the plural form. This would be a good and working example.
devise_scope :user do match "/some/route" => "some_devise_controller" end devise_for :users
Notice and be aware of the differences above between :user and :users

Allow you to route based on whether a scope is not authenticated. You can optionally specify which scope.
unauthenticated do as :user do root :to => 'devise/registrations#new' end end root :to => 'dashboard#show'
