将 Ruby on Rails 中的 500/404 错误保存到数据库？

发布于 2024-12-07 03:41:36 字数 255 浏览 0 评论 0原文

有没有办法将 500/404 等错误保存到数据库中，以便您可以检查它们以查看网站上是否存在任何错误？

我以为你可以从 500.html 页面发送 JS AJAX 请求。例如

/errors/create/?message=error_message&ip=123&browser=ie9

，但我不确定在生产模式下运行时如何获取该信息？

非常感谢任何帮助，

Is there a way to save the 500/404 etc errors to your database so you can check them to see if there are any bugs on the site?

I thought you could send an JS AJAX request from the 500.html page. e.g.

/errors/create/?message=error_message&ip=123&browser=ie9

But I'm not sure how to get that information when running in production mode?

Any help greatly appreciated,

Alex

这就是我的应用程序控制器中的内容：

def rescue_action_in_public(exception)
  #This is called every time a non-local error is thrown.
  #Copy the error to the db for later analysis.
  Error.create :exception_name => exception.exception.to_s, :backtrace_info => exception.backtrace.to_s
  #Then handle the error as usual:
  super
end

如您所见，我创建了一个错误模型，每当发生错误时都会将一个新模型保存到数据库中。要记住的一件事是，回溯对于字符串列来说太大了，因此您需要更大的东西，例如文本类型。这适用于我的 Rails 3.0.5 应用程序。

This is what I have in my application controller:

def rescue_action_in_public(exception)
  #This is called every time a non-local error is thrown.
  #Copy the error to the db for later analysis.
  Error.create :exception_name => exception.exception.to_s, :backtrace_info => exception.backtrace.to_s
  #Then handle the error as usual:
  super
end

As you can see I have an Error model I created and this saves a new one to the DB whenever it happens. One thing to remember is that backtraces are much to big for string columns so you will need something bigger like a text type. This works in my Rails 3.0.5 app.
