Devise + omniauth twitter + authentications table - ruby-on-rails

Question

When I authenticate through my twitter sign in button, I'm getting this browser error
The action 'new' could not be found for RegistrationsController
I created a registrations_controller.rb to override the devise controller for some methods according to this guide http://www.orhancanceylan.com/rails-twitter-and-facebook-authentications-with-omniauth-and-devise/#comment-1375
Sorry to be verbose about the code. The the main part is in the authentications_controller.rb in the twitter method, in the else portion of the method.
That portion of the code governs when a user does not have other 3rd party signin authentications previously created AND not signed in via devise. Thus an authentication record and a user record must be created in that portion of the code. But I'm getting the error.
There is an authentications table so that I can add other omniauth strategies.
If unclear, or more information is needed, please let me know how I can improve the question.

Answer 1

I was inheriting registrations_controller from the wrong controller.
It should be
class RegistrationsController < Devise::RegistrationsController
not
class RegistrationsController < ApplicationController
