姜戈 404 困境
我的 404 设置中有一个错误。我知道这一点，因为当我尝试访问某个不存在的页面时，我会收到服务器错误模板。但该模板毫无用处，因为它没有给我任何调试信息。为了获得 django 的调试页面，我需要在设置文件中设置 DEBUG=True 。但如果我这样做，错误就不会出现，因为 django 不会尝试访问我的错误 404 设置。那么你们觉得怎么样？
这是在我的根 url 文件中： handler404 = 'portal.blog.views.handlenotfound' 这是在portal.blog.views.handlenotfound中：
def handlenotfound(request):
global common_data
datas = {
'tags' : Tag.objects.all(),
'date_list' : Post.objects.filter(yayinlandi=True).dates("pub_date","year")
}
data.update(common_data)
return render_to_response("404.html",datas)Edit:
我想我还需要返回 HttpResponseNotFound 对吗？
I have a bug in my 404 setup. I know that because, when I try to reach some page which doesn't exist, I get my server error template. But that templates is useless because it doesn't give me any debug info. In order to get django's debug page, I need to set DEBUG=True in settings file. But if I do that, bug doesn't appear because django doesn't try to access my buggy 404 setup. So what do you guys think?
This is in my root urls file:handler404 = 'portal.blog.views.handlenotfound' And this is in portal.blog.views.handlenotfound:
def handlenotfound(request):
global common_data
datas = {
'tags' : Tag.objects.all(),
'date_list' : Post.objects.filter(yayinlandi=True).dates("pub_date","year")
}
data.update(common_data)
return render_to_response("404.html",datas)Edit:
I guess I also need to return a HttpResponseNotFound right?

如果我必须调试此类错误，我会
暂时将处理程序转换为由自定义 url 提供服务的简单视图，这样 django 的内部机制就不会妨碍，或者
（暂时）将处理程序代码包装在 try.. except 块中以记录您可能遇到的任何错误missed
无论如何，您确定如果 DEBUG=true 则不会调用您的处理程序吗？
If I had to debug this kind of errors, I would either
temporarily turn the handler into a simple view served by a custom url, so that django's internal mechanisms don't get into the way, or
(temporarily) wrap the handler code in a try..except block to log any error you may have missed
Anyway, are you sure your handler doesn't get called if DEBUG=true?
data.update(common_data)应为datas.update(common_data)。（顺便说一句，data 已经是复数形式：单数是 datum。）
data.update(common_data)should bedatas.update(common_data).(Incidentally, data is already plural: the singular is datum.)
