@Neil Also make sure that you restart the application. After performing all devise setup steps for the changes to take effect. — Kirti Thorat, Mar 18 '14 at 21:46

The main problem is here

NoMethodError (undefined method `encrypted_password=' for #<Post:0x007fde3e09e538>):

Check out you migration file. Is encrypted_password present or not? Do you have this t.string :encrypted_password, :null => false, :default => "" line of code in your migration file. And in your model file (i.e post.rb) you haven't define password attribute too.

i have this t.string :encrypted_password, :null => false, :default => "" in my migration file but my post.rb is this devise :database_authenticatable, :registerable, :recoverable, :rememberable, :trackable, :validatable do i add :encrypted_password – Neil Mar 18 '14 at 21:16
Have you add "attr_accessible :email, :password, :password_confirmation, :remember_me" in your post.rb – Amrit Dhungana Mar 18 '14 at 21:21
no because thought i didnt think we use that command on rails 4? – Neil Mar 18 '14 at 21:26
Sorry, You are right you don't need thtat line in rails4. If show rollback the db and migrate it again. – Amrit Dhungana Mar 18 '14 at 21:36

I tried adding the migration and the attributes in the userscontroller and it did not work http://stackoverflow.com/posts/30269771/edit – codigomonstruo May 15 '15 at 23:44
def change add_column :users, :provider, :string add_column :users, :uid, :string add_colum :users, :encrypted_password, :string end end – codigomonstruo May 15 '15 at 23:49
