Python Django Handling Custom Error Page

To handle error reporting in Django, you can utilize Django's built-in form validation mechanisms and Django's error handling capabilities. In this article, I'll demonstrate how to implement error handling. If there are errors in the form submission, the user will be notified of the errors.

Required Modules

• Install Django
• Create Virtual Env

Setting up the Django Files

views.py: This code defines three view functions for a Django web application:

• home(request): Returns a "Hello, World!" response for the root URL.
• error_404(request, exception): Handles HTTP 404 errors (Not Found) and renders a 404 template.
• error_500(request): Handles HTTP 500 errors (Internal Server Error) and renders a 500 template (though there's a potential typo in the template name).

from django.http import HttpResponse
from django.shortcuts import redirect, render
from django.db import models
from .models import Product


def home(request):
    return HttpResponse('Hello, World!')


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

def error_500(request):
    return render(request, 'myapp/error_505.html', status=500)
