未定義的方法`確認！'爲＃<User>

我創建了這個文件的文件seeds.rb INDB/seeds.rb代碼未定義的方法`確認！'爲＃<User>

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

它給我錯誤

，因爲它創建正在運行的用戶在開發數據庫，但是當它來到線 user2.confirm！它拋出這個未定義的方法錯誤我無法指出爲什麼一個實例確認！方法正在運行，第二個實例顯示未定義？

您使用的設計爲用戶模型就像一個確認的象徵？因爲據我所知AR沒有確認！方法 – jizak

yesi正在使用devise –

確保在'User'類的'devise'方法參數中有'：confirmable'。 –

當您在模型中包含可確認模塊時，確認設計的功能。從它的外觀來看，我認爲你沒有在你的模型中使用過它。

你的代碼應該有以下

class User < ActiveRecord::Base 

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

end
