【问题描述】：

我创建了一个文件seeds.rb indb/seeds.rb 这个文件的代码是

puts 'SETTING UP DEFAULT USER LOGIN'
user = User.create! :name => 'My Fir User', :email => 'rashmi@example.com', :password => 'please', :password_confirmation => 'please'
user.confirm!
user2 = User.create! :name => 'My Second User', :email => 'user2@example.com', :password => 'please', :password_confirmation => 'please'
user2.confirm!
puts 'New user created: ' << user.name

它给了我错误

rake aborted!

它正在为用户运行，因为它是在开发数据库中创建的，但是当它上线时用户2.确认！它抛出这个未定义的方法错误我无法指出为什么例如确认！方法正在运行，第二个实例显示未定义？？

【问题讨论】：

您使用的是用户模型的设计吗？因为据我所知，AR 没有确认！方法
确保在devise 类中的:confirmable 方法参数中有User。

【解决方案1】：

当您在模型中包含可确认模块时，设计的确认功能就会出现。从外观上看，我认为您没有在模型中使用它。

您的代码应该有一个如下所示的可确认符号

class User < ActiveRecord::Base

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

end
