Ruby on rails omniauth与authlogic问题与身份验证方法

我一直在学习本教程：。我经历了这一切，我得到了这个错误：

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

我是否需要将关系添加到用户模型以进行身份验证

我的用户模型当前如下所示：

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

我的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

你需要加上这个

class User < ActiveRecord::Base
  has_many :authentications

还要注意 omniauth['user_info']['email'] 改为

---

omniauth['info']['email']

是否需要运行迁移来创建身份验证表？是的，我创建了教程中显示的迁移并运行了它。

class User < ActiveRecord::Base
  has_many :authentications
