undefined local variable or method `confirmed_at' for #User

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

class AddConfirmableToDevise < ActiveRecord::Migration   def change     change_table(:users) do |t|        t.confirmable      end     add_index  :users, :confirmation_token, :unique => true    end end 

I do have devise :confirmable added in User model.

My rake db:migrate gives no output. and my sign up page gives the error:

undefined local variable or method 'confirmed_at' for #User 

Anybody has a clue?

Answer 1

Ok. I solved it. The migration is outdated. Generate new migration with same code but another name.

1.Run command:

rails g migration add_confirmable_to_devise_v1 

2.In the migration file:

class AddConfirmableToDeviseV1 < ActiveRecord::Migration   def change     change_table(:users) do |t|        t.confirmable      end     add_index  :users, :confirmation_token, :unique => true    end end 

3.Then

rake db:migrate

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
