omniauth與身份驗證方法authlogic問題

Question

我一直在關注本教程：http://emumair.wordpress.com/2011/03/17/social-network-authentication-with-omniauth-and-authlogic/。我通過這一切走了，我得到這個錯誤：

undefined method `authentications' for #User<User:0x54cd8d8> 

其未能在控制器中：應用程序/控制器/ authentications_controller.rb：21：在'創造'：

user.authentications.build(:provider => omniauth['provider'], :uid => omniauth['uid']) 

我是否需要爲用戶模型添加認證的關係？

我的用戶模型目前看起來是這樣的：

class User < ActiveRecord::Base 
acts_as_authentic 

def apply_omniauth(omniauth) 
self.email = omniauth['user_info']['email'] 

# Update user info fetching from social network 
case omniauth['provider'] 
when 'facebook' 
# fetch extra user info from facebook 
when 'twitter' 
# fetch extra user info from twitter 
end 
end 
end 

我authentication.rb文件是：

class Authentication < ActiveRecord::Base 
belongs_to :user 
validates :user_id, :uid, :provider, :presence => true 
validates_uniqueness_of :uid, :scope => :provider 
end 

Answer 1

您需要添加此

class User < ActiveRecord::Base 
    has_many :authentications 

還要注意的是 omniauth ['user_info'] ['email'] 更改爲 omniauth ['info'] ['email']
