Question

Are controllers in devise automatically generated? How do you access them?

I know for views you do
rails generate devise_views.

Answer 1

Devise uses internal controllers, which you can access and subclass in your own code. They are under the Devise module. For example, to extend the RegistrationsController:

class MembershipsController < Devise::RegistrationsController
  # ...
end

Then all you have to do is configure Devise’s routes to use your controller instead:

devise_for :members, :controllers => { :registrations => 'memberships' }
