我刚刚在 Ubuntu Hardy 8.04 VPS 上安装了 Ruby Enterprise Edition 和 Passenger。据我所知，安装成功。我的 Rails 应用程序是可访问的，并且总体上运行良好。但是，我的应用程序中用户可以使用 AJAX 发表评论的部分不起作用。根据Railscasts 第 65 集，我的Comment模型有一个请求的 setter 方法：

def request=(request) 
  logger.info '*** Entered request setter method ***' # <- Never output!
  self.ip_address = request.remote_ip
  self.user_agent = request.env['HTTP_USER_AGENT']
  self.referrer   = request.env['HTTP_REFERER']
end

在开发中一切正常，但在生产中永远不会调用此方法，并且在尝试发表评论时出现 HTTP 500 错误。我的生产日志如下所示。

我对如何调试这个有点不知所措，所以不胜感激任何指针！我不知道是什么试图用一种方法对Fixnum班级进行猴子修补。each

编辑：事实证明，Hoptoad 异常通知程序存在一个已知问题，可以解释该Fixnum问题。它仍然没有解释为什么我的请求设置器没有被 REE 调用！

删除 Hoptoad 并重试。从我在堆栈跟踪的文本墙中可以看出，您的控制器没有被调用。试图解析传入的参数时它正在爆炸。
