Question

Hello Programmers＆amp;开发人员!!!，当我尝试访问rails console时，我在DeviseMultipleTokenAuthDevice遇到问题，然后我收到以下错误：

Loading development environment (Rails 4.2.0)
2.2.4 :001 > DeviseMultipleTokenAuthDevice
NameError: uninitialized constant DeviseMultipleTokenAuthDevice
    from (irb):1
    from /Users/vishal/.rvm/gems/ruby-2.2.4@devise_demo/gems/railties-4.2.0/lib/rails/commands/console.rb:110:in `start'

    from script/rails:6:in `<main>'

以下我在项目中使用的宝石用于用户身份验证

gem 'devise'
gem 'devise_multiple_token_auth'

以下是我记录中的表格：

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 >

同样的解决方案是，我们要在app / models /

中创建一个名为devise_multiple_token_auth_device.rb的文件

这里是 devise_multiple_token_auth_device.rb 文件的代码

class DeviseMultipleTokenAuthDevice < ActiveRecord::Base
  belongs_to :user
end

NameError：未初始化的常量DeviseMultipleTokenAuthDevice
