未初始化的常量User :: LinkedinConnection

我正在尝试使用linkedin实现登录，在用户模型中我有以下方法：

def connect_to_linkedin (auth)
    self.provider=auth.provider
    self.uid=auth.uid
    self.user_linkedin_connection = User::LinkedinConnection.new(:token => auth["extra"]["access_token"].token, :secret => auth["extra"]["access_token"].secret)
    unless self.save
       return false
    end
    true
  end

但是我收到了这个错误：“未初始化的常量User :: LinkedinConnection ”

这是框架跟踪：
