Allow just that user actived sign_in - Devise

Question

I'm using devise for authentication and have a activated:boolean on users table.
How can I only allow the activated users to sign in? And show the flash message:

Login successful for users activated and Login denied for users non-activated / deactivated users

Thanks!

Answer 1

To prevent deactivated users from signing in, override active_for_authentication? on your User model:

def active_for_authentication?
  super && activated
end
