Django, custom error pages redirects to 500 instead of 404

Question

I have production server which has these settings:

DEBUG = False
ALLOWED_HOSTS = ['localhost', '127.0.0.1', 'my.ip.address', 'example.com']

Then in my main urls.py file I have added this:

from django.conf.urls import url, include, handler404, handler500

handler500 = 'main.views.error_500'
handler404 = 'main.views.error_404'

My main.views has these:

def error_404(request):
    return render(request, 'main/errors/404.html', status=404)


def error_500(request):
    return render(request, 'main/errors/500.html', status=500)

When I deploy my production server and try to open page that does not exists, it should redirect to my error_404 view. However, it redirects to my error_500 view. Why this is happening?

Answer 1

This question is three months old but for the community this is how I solved this:

The 404-page-not-found-view needs an "exception" argument:

def error_404(request, exception):
    return render(request,'myapp/404.html', status = 404)

The default 404 view will pass two variables to the template: request_path, which is the URL that resulted in the error, and exception, which is a useful representation of the exception that triggered the view (e.g. containing any message passed to a specific Http404 instance).

Source: https://docs.djangoproject.com/en/2.1/ref/views/#the-404-page-not-found-view

I'm Django-noob but I suppose that without this argument the 404 trigger a 500.

One more thing: It works for me without the import : "from django.conf.urls import handler404, handler500"
