Devise 'translation missing' error with subclassed controller

问题

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

But, when I sign up a new admin, for example, the flash shows the message:

translation missing: en.devise.admin_registrations.admin.signed_up

I've verified an entry exists in config/locales/devise.en.yml. Here's the snippet:

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

What am I missing?

回答1:

You must do this :

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