Problem with routes using Devise and Omniauth

Question

I try to get OAuth and Devise to work together, but I get Controller::RoutingError (No route matches "/users/auth/facebook/callback"): when trying to log in via Facebook.

Oddly enough, the problem does not occur with Google Apps. (same callback route).

Any ideas?

callback_controller:

 class Users::OmniauthCallbacksController < Devise::OmniauthCallbacksController def facebook # You need to implement the method below in your model @user = User.find_for_facebook_oauth(env["omniauth.auth"], current_user) if @user.persisted? flash[:notice] = I18n.t "devise.omniauth_callbacks.success", :kind => "Facebook" sign_in_and_redirect @user, :event => :authentication else session["devise.facebook_data"] = env["omniauth.auth"] redirect_to new_user_registration_url end end def google_apps @user = User.find_for_google_apps_oauth(env["omniauth.auth"], current_user) if @user.persisted? flash[:notice] = I18n.t "devise.omniauth_callbacks.success", :kind => "Google Apps" sign_in_and_redirect @user, :event => :authentication else session["devise.google_apps_data"] = env["omniauth.auth"] redirect_to new_user_registration_url end end def passthru render :file => "#{Rails.root}/public/404.html", :status => 404, :layout => false end end 

routes.rb:

 devise_for :users, :controllers => { :omniauth_callbacks => "users/omniauth_callbacks" } do get '/users/auth/:provider' => 'users/omniauth_callbacks#passthru' end 

Why :provider => "facebook" raises a RoutingError but not :provider => "google_apps" ?

Answer 1

Found:

in the user device model, I had a module:: :omniauth_providers => [:facebook, :openid, :google_apps] added, which (apparently) does not do what I thought it did. I deleted the line and now all my authentication logic is working correctly again.
