使用 Facebooker 和 Ruby on Rails 时出现会话问题

我正在阅读《Facebook 平台开发》一书，以便尝试为 Facebook 编写一个小游戏，我遇到了一个“小”问题：我试图在每次登录时将用户插入到我计算机的数据库中。我正在使用书中编写的几种方法，但似乎存在一些问题：

我似乎无法使用 RoR 的 Facebooker 帮助程序从 Facebook 检索 session_key，因此该值在。
每次重新加载网页时，我都可以看到，即使 facebook_id 相同，同一用户也会添加到数据库表的另一行中，尽管它不应该；如果发生变化，它只是应该更新属性 session_key - 无论如何，现在这是 null。

以下是我为了执行这一切而使用的三种方法：

def self.for(facebook_id,facebook_session=nil)
    user = User.find_or_create_by_facebook_id(facebook_id)
    unless facebook_session.nil?
      user.store_session(facebook_session.session_key)
    end
  end

  def store_session(session_key)
    if self.session_key != session_key
      update_attribute(:session_key, session_key)
    end
  end

  # Re-create a Facebooker::Session object outside a request
  def facebook_session
    @facebook_session ||= returning Facebooker::Session.create do |session|
      # Facebook sessions are good for only one hour storing
      session.secure_with!(session_key,facebook_id,1.hour.from_now)
    end
  end

提前非常感谢大家！1。

I am reading the book Facebook Platform Development in order to try to code a small game for Facebook, and I have come across a "little" problem: I am trying to insert a user every time this is logged, into a database in my computer. I am using a couple of methods written in the book, but there seems to be a couple of problems:

I can't seem to retrieve the session_key from Facebook using the Facebooker helpers for RoR, and thus this value is null into the table in my database.
Every time I reload the webpage, I can see that even though the facebook_id is the same, the same user is added in another row to my table in the database, even though it shouldn't; it's just supposed to update the attribute session_key if this changes -anyway, right now this is null.

These are the three methods I am using in order to perform all this:

def self.for(facebook_id,facebook_session=nil)
    user = User.find_or_create_by_facebook_id(facebook_id)
    unless facebook_session.nil?
      user.store_session(facebook_session.session_key)
    end
  end

  def store_session(session_key)
    if self.session_key != session_key
      update_attribute(:session_key, session_key)
    end
  end

  # Re-create a Facebooker::Session object outside a request
  def facebook_session
    @facebook_session ||= returning Facebooker::Session.create do |session|
      # Facebook sessions are good for only one hour storing
      session.secure_with!(session_key,facebook_id,1.hour.from_now)
    end
  end

Thanks a lot in advance to everybody!1.
