Question

I’m using Devise and OmniAuth (Facebook) in a Rails 3 app. I just started noticing this behavior recently.

When a user signs in, he is redirected to his dashboard, however, the characters “#_” are being appended to the url. The only thing I can think of now is a conflict between the routes created by:

  resources :users

and

  # User Authentication
  devise_for :users,
         :singular => :user,
         :controllers => {:registrations => 'registrations'} do
    get 'logout' => 'devise/sessions#destroy'
  end

Answer 1

Is this only happening with Facebook? If so it is probably related to: https://developers.facebook.com/blog/post/552/. Notice how Facebook outlines that they changed the session redirect handling to append a #_=_ to responses. I’m not sure why this was done, however you may be able to fix it by supplying an explicit redirect url.
