Devise + Facebook omniauth: facebook action not found for Devise :: OmniauthCallbacksController

Question

I found similar threads on SO, but none of them helped me solve this problem. My routes look like this:

devise_for :users do post '/users' => 'registrations#create', :as => 'user_registration' end devise_for :users, :controllers => {:omniauth_callbacks => "users/omniauth_callbacks"} 

Ive also tried:

 devise_for :users, :controllers => {:omniauth_callbacks => "omniauth_callbacks"} 

But I still get

 The action 'facebook' could not be found for Devise::OmniauthCallbacksController 

I even tried to restart the server, but that didn't help me. I follow this tutorial .

omniauth_callbacks_controller.rb :

 class Users::OmniauthCallbacksController < Devise::OmniauthCallbacksController def facebook @user = User.find_for_facebook_oauth(request.env["omniauth.auth"], current_user) if @user.persisted? puts @user.inspect flash[:notice] = I18n.t "devise.omniauth_callbacks.success", :kind => "Facebook" sign_in_and_redirect @user, :event => :authentication else session["devise.facebook_data"] = request.env["omniauth.auth"] redirect_to new_user_registration_url end end end 

Answer 1

Change the development route to

  devise_for :users, :controllers => { :omniauth_callbacks => "users/omniauth_callbacks" } 

to make sure it matches your controller definition.

Answer 2

Check your routes. Perhaps they are generated twice. Try:

 devise_for :users, :controllers => {:omniauth_callbacks => "users/omniauth_callbacks"} devise_scope :users do post '/users' => 'registrations#create', :as => 'user_registration' end
