Devise 'translation missing' error with subclassed controller

Question

I\'ve subclassed Devise::RegistrationsController. The subclassed controller, in my case, is AdminRegistrationsController.

But, when I sign up

Answer 1

You must do this :

en:
  devise:
    admin_registrations:
      admin:
        signed_up: 'Welcome! You have signed up successfully.'
