NameError: uninitialized constant DeviseMultipleTokenAuthDevice

Hello Programmers & Developers!!!, I'm facing a problem in rails console when I tried to access DeviseMultipleTokenAuthDevice then I'm getting the following error :

Loading development environment (Rails 4.2.0)
2.2.4 :001 > DeviseMultipleTokenAuthDevice
NameError: uninitialized constant DeviseMultipleTokenAuthDevice

Following gems I'm using in my project for user authentication

gem 'devise'
gem 'devise_multiple_token_auth'


Following are the tables in my record :

2.2.4 :002 > p ActiveRecord::Base.connection.tables
["schema_migrations", "users", "devise_multiple_token_auth_devices"]
 => ["schema_migrations", "users", "devise_multiple_token_auth_devices"] 
2.2.4 :003 >

The solution for the same is, we've to create a file called devise_multiple_token_auth_device.rb in app/models/


here is the code for devise_multiple_token_auth_device.rb file

class DeviseMultipleTokenAuthDevice < ActiveRecord::Base
  belongs_to :user
end
