Instance Method Details

#authenticate(scope = nil, block = nil) ⇒ Object

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", :as => :user_root
end

def authenticate(scope=nil, block=nil)
  constraints_for(:authenticate!, scope, block) do
    yield
  end
end

#authenticated(scope = nil, block = nil) ⇒ Object

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', :as => :admin_root
end

authenticated do
  root :to => 'dashboard#show', :as => :authenticated_root
end

authenticated :user, lambda {|u| u.role == "admin"} do
  root :to => "admin/dashboard#show", :as => :user_root
end

root :to => 'landing#show'

#devise_for(*resources) ⇒ Object

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.

Examples

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    /users/sign_in                    {:controller=>"devise/sessions", :action=>"new"}
         user_session POST   /users/sign_in                    {:controller=>"devise/sessions", :action=>"create"}
 destroy_user_session DELETE /users/sign_out                   {:controller=>"devise/sessions", :action=>"destroy"}

# Password routes for Recoverable, if User model has :recoverable configured
    new_user_password GET    /users/password/new(.:format)     {:controller=>"devise/passwords", :action=>"new"}
   edit_user_password GET    /users/password/edit(.:format)    {:controller=>"devise/passwords", :action=>"edit"}
        user_password PUT    /users/password(.:format)         {:controller=>"devise/passwords", :action=>"update"}
                      POST   /users/password(.:format)         {:controller=>"devise/passwords", :action=>"create"}

# Confirmation routes for Confirmable, if User model has :confirmable configured
new_user_confirmation GET    /users/confirmation/new(.:format) {:controller=>"devise/confirmations", :action=>"new"}
    user_confirmation GET    /users/confirmation(.:format)     {:controller=>"devise/confirmations", :action=>"show"}
                      POST   /users/confirmation(.:format)     {:controller=>"devise/confirmations", :action=>"create"}

Options

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 /accounts instead of /users:

    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

Scoping

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

Adding custom actions to override controllers

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_scope entry should look like this:

devise_scope :owner do
  post "deactivate", :to => "registrations#deactivate", :as => "deactivate_registration"
end

#devise_scope(scope) ⇒ Object Also known as: as

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
  get "/some/route" => "some_devise_controller"
end
devise_for :users

Notice and be aware of the differences above between :user and :users
