Question

I am using Rails 3. There is a possible duplicate here. But it did not solve my problem, neither did any other solution.

My migration is as follows

Answer 1

As of the latest devise, you just need to remove comments from the following lines on the devise users migration.. (2013....._devise_create_users.rb)

  # Confirmable
  t.string   :confirmation_token
  t.datetime :confirmed_at
  t.datetime :confirmation_sent_at
  t.string   :unconfirmed_email # Only if using reconfirmable
