我在 Django 中看不到我的 404 和 500 自定义页面

Question

I am trying to make custom 404 and 500 pages in my Django project, but when I use these codes I can't see any result!

views.py:

def handle404(request,exception):
    return render(request,'400.html',status=404)

def handle500(request):
    return render(request,'500.html',status=500)

url.py :

handler404 ='base.views.handle404'
handler500 = 'base.views.handle500'

i see only this page : enter image description here

anybody have some suggestions to improve my code ?

Answer 1

Have you created the 400.html in your templates? By that, I mean you follow standard Django patterns: app_name/templates/app_name/400.html ?

(By the way, I would strongly recommend, that you keep the names matching to the errors. That way you can fast navigate in your HTMLs and you don't have to remember what HTML handles which error)

UPDATE

You have to enter a specific path to the HTML into the render function.

Meaning: If your error HTML lives in the app test_app your path would be test_app/400.html :

def handle404(request,exception):
    return render(request,'test_app/400.html',status=404)

Answer 2

Not sure if you have set DEBUG=False in your settings.py file.

But this worked for me:

Within my app.views :

# Handler error page 404
def handler404(request, exception):
     return render(request, '404.html', {})


# Handler error page 500
def handler500(request):
     return render(request, '500.html', {})

In the return statement , I have passed an empty context, {} .

Within my project's urls.py file:

handler404 = 'app.views.handler404'
handler500 = 'app.views.handler500'

setting.py file:

DEBUG=False
