NoMethodError: undefined method `confirm!' for #<User

Question

I am trying to create an app using rails app composer tool. I am using Devise with confirmable. I am getting the error

rake db:seed
rake aborted!
NoMethodError: undefined method `confirm!' for #<User:0xa0b26ec>

during the installation process.

Already the user.rb file has :confirmable

  devise :database_authenticatable, :registerable, :confirmable,
     :recoverable, :rememberable, :trackable, :validatable

I am not able to do rake db:seed.

Answer 1

The #confirm! method has been removed.

You have to use an older version or, what's better switch to the #confirm method.
