在自定义500处理程序中捕获错误文本 [英] Catch error text in custom 500 handler

问题描述

在我的某个地方，我抛出了一个错误，尤其是这个错误:

Somewhere in my views, I throw an error, particularly this one:

views.py

from xmlrpclib import Fault

def some_function(request):
    if ....:
        return Fault(-1, 'foo')

然后，也在 views.py 中，我有自定义的500处理程序来捕获服务器错误:

Then, also in views.py, I have my custom 500 handler to catch server errors:

def my_custom_500(request):
    context = {...}
    ### Here is where I need to catch `'foo'` 
    ### in order to put it in the context and pass it to the template
    render(request, '500.html', context)

无论如何我都可以访问该错误消息?谢谢

Is there anyway in which I can access the error message? Thanks

推荐答案

尝试覆盖 urls.py 中的 django.conf.urls.defaults.handler500 .

from django.conf.urls.defaults import *
handler500 = 'path.to.my_custom_500'

甚至更好-编写自己的处理程序并将其放在 LOGGING 设置.

or even better - write your own handler and put it in the LOGGING settings.

修改:

您还可以在您的 my_custom_500 代码中添加可识别异常类型的代码，例如:

You can also add to your my_custom_500 code that will recognize type of exception, eg:

import sys; 

def my_custom_500(request):
    ...
    type_, value, traceback = sys.exc_info()
    ...
