Question

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

它正在为用户运行，因为它是在开发数据库中创建的，但是当它出现时 user2.confirm！它抛出这个未定义的方法错误我无法指出为什么一个实例确认！方法正在运行，对于第二个实例，它显示未定义??

Answer 1

在模型中包含可确认模块时，确认设计功能。从它的外观来看，我认为你没有在你的模型中使用它。

您的代码应该有一个可识别的符号，如下所示

class User < ActiveRecord::Base

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

end

未定义的方法`确认！'对于＃<user> </user>
