Ruby on rails 控制器未保存属性（来自FB的Oauth令牌）

奇怪的问题-我的一个控制器中的创建操作没有保存属性-请查看下面的代码。所有的线路都能工作到最后2分钟。未保存

oauth\u令牌

和

oauth\u到期时间

。我已经检查了属性是否正确命名，等等。有趣的是，如果我将第二行改为最后一行：

omniauth['credentials']['token']？provider=omniauth['credentials']['token']：provider=''

它工作得非常好。实际属性

oauth\u令牌

和

oauth\u到期时间

似乎有问题。然后，我尝试创建两个新的虚拟属性，看看它是否在那里工作-没有。似乎在

oauth\u令牌

之后创建的任何属性都会出错。这是移民问题吗？有什么想法吗

def create
    params[:authorization] ? authorization_route = params[:authorization] : authorization_route = 'no authorization (invalid callback)'

    omniauth = request.env["omniauth.auth"]
    if omniauth and params[:authorization]
        if authorization_route == "facebook"
              omniauth['extra']['raw_info']['email'] ? email =  omniauth['extra']['raw_info']['email'] : email = ''
              omniauth['extra']['raw_info']['name'] ? name =  omniauth['extra']['raw_info']['name'] : name = ''
              omniauth['extra']['raw_info']['id'] ?  uid =  omniauth['extra']['raw_info']['id'] : uid = ''
              omniauth['provider'] ? provider =  omniauth['provider'] : provider = ''
              omniauth['credentials']['token'] ? oauth_token =  omniauth['credentials']['token'] : oauth_token = ''
              omniauth['credentials']['expires_at'] ? oauth_expires_at =  Time.at(omniauth['credentials']['expires_at']) : oauth_expires_at = ''
end
   end

我不确定这是否是您的问题，但我认为您使用三元（

condition？value:other_value

）语法的方式是不典型的。通常，你会写这样的东西

def create
  authorization_route = params[:authorization] ? params[:authorization] : 'no authorization (invalid callback)'

  omniauth = request.env["omniauth.auth"]
  if omniauth and params[:authorization]
    if authorization_route == "facebook"
      email = omniauth['extra']['raw_info']['email'] ? omniauth['extra']['raw_info']['email'] : ''
      name = omniauth['extra']['raw_info']['name'] ? omniauth['extra']['raw_info']['name'] : ''
      uid = omniauth['extra']['raw_info']['id'] ? omniauth['extra']['raw_info']['id'] : ''
      provider = omniauth['provider'] ? omniauth['provider'] : ''
      oauth_token = omniauth['credentials']['token'] ? omniauth['credentials']['token'] : ''
      oauth_expires_at = omniauth['credentials']['expires_at'] ? Time.at(omniauth['credentials']['expires_at']) : ''
    end
  end
  # ...
end

但是，既然你用它来做

attribute=value？值：默认值

，您可以通过对除最后一个之外的所有对象使用or（

|

）运算符来进一步简化它：

def create
  authorization_route = params[:authorization] || 'no authorization (invalid callback)'

  omniauth = request.env["omniauth.auth"]
  if omniauth and params[:authorization]
    if authorization_route == "facebook"
      email = omniauth['extra']['raw_info']['email'] || ''
      name = omniauth['extra']['raw_info']['name'] || ''
      uid = omniauth['extra']['raw_info']['id'] || ''
      provider = omniauth['provider'] || ''
      oauth_token = omniauth['credentials']['token'] || ''
      oauth_expires_at = omniauth['credentials']['expires_at'] ? Time.at(omniauth['credentials']['expires_at']) : ''
    end
  end
  # ...
end

但是，这三种方法都可以工作，因此，

omniauth['credentials']['token']

不是正确的散列键，或者无论您稍后在控制器或模型中使用

oauth_token

和

oauth_expires_做什么都会导致问题

您能否编辑您的问题，以包含更多来自控制器和用户模型的代码？
我很不好意思承认问题的实质：

完全忘记了我后来在控制器中所做的事情。我喜欢粗心的错误

必须改变：

user.authorizations.build(:provider => provider, :uid => uid, :name => name, :email => email, :user_id => user.id)

致：

user.authorizations.build(:provider => provider, :uid => uid, :name => name, :email => email, :user_id => user.id, :oauth_token => oauth_token, :oauth_expires_at => oauth_expires_at)
