Rails & Devise: Override SessionsController

Question

I\'m trying to set up a sign in form on my home page. I managed to do it by following the Wiki

Except, if the login infos are incorrect, the /devise/session/new.ht

If you're running into the error undefined method 'users_url' for # when overriding the devise sessions controller you can provide a path name as below. The important addition that you missed is the , :as => :users.

  devise_scope :user do
    root :to => "devise/sessions#new", :as => :users
    get "sign_in", :to => "devise/sessions#new"
    get "sign_out", :to => "devise/sessions#destroy"
    get "sign_up", :to => "devise/registrations#new"
  end

The above route name might conflict with existing or future routes. As an alternative, I have found that this setup tends to work well:

  devise_for :users,
    :path_names  => { :sign_out => 'logout', 
                      :sign_in  => 'login', 
                      :sign_up  => 'register' },
    :controllers => { :sessions => 'users/sessions' } do

      # Sessions
      post '/login'         => 'users/sessions#create',       :as => :user_session
      get  '/login'         => 'users/sessions#new',          :as => :new_user_session
      get  '/logout'        => 'users/sessions#destroy',      :as => :destroy_user_session

      # Passwords
      post '/password'      => 'devise/passwords#create',     :as => :user_password
      put  '/password'      => 'devise/passwords#update'
      get  '/password/new'  => 'devise/passwords#new',        :as => :new_user_password
      get  '/password/edit' => 'devise/passwords#edit',       :as => :edit_user_password

      # Registrations
      post   '/register'    => 'devise/registrations#create', :as => :user_registration
      get    '/register'    => 'devise/registrations#new',    :as => :new_user_registration
      get    '/account'     => 'devise/registrations#edit',   :as => :edit_user_registration
      put    '/account'     => 'devise/registrations#update'
      delete '/account'     => 'devise/registrations#destroy'

  end
