Creating Custom 404 and 500 Error Pages in Django: A Step-by-Step Guide

Hello Readers,

In the world of web development, ensuring a smooth and user-friendly experience is crucial. One way to do this is by creating custom 404 and 500 error pages. Today, we'll be focusing on how to create these custom error pages in a Django project.

What are 404 and 500 Error Pages?

A 404 error page is displayed when the server can't find the requested page. This usually happens when a page has been removed or the URL has been changed without redirection.

A 500 error page, on the other hand, appears when the server encounters an error it can't handle. This usually means something has gone wrong with your code.

Creating a Custom 404 Page in Django

1. Create Your 404 Page: First, create an HTML file for your custom 404 page. You might name it '404.html'. This file should go in your project's templates directory.
2. Update Your Django Settings: Next, you need to tell Django to use your custom 404 page. In your settings.py file, ensure that DEBUG is set to False and ALLOWED_HOSTS is set to your domain name.
3. Create a View for Your 404 Page: Django uses views to handle requests. In your views.py file, create a view for your 404 page.

from django.shortcuts import render

def view_404(request, exception):
    return render(request, "404.html")

4. Update Your urls.py File: Finally, you need to update your urls.py file to use your custom 404 view. Add the following line to your urls.py file:

handler404 = 'myapp.views.view_404'

Creating a Custom 500 Page in Django

1. Create Your 500 Page: Create an HTML file for your custom 500 page, named '500.html'. This file should also go in your project's templates directory.
2. Create a View for Your 500 Page: In your views.py file, create a view for your 500 page.

from django.shortcuts import render

def view_500(request):
    return render(request, "500.html")

3. Update Your urls.py File: Update your urls.py file to use your custom 500 view. Add the following line to your urls.py file:

handler500 = 'myapp.views.view_500'

Creating custom 404 and 500 error pages can significantly improve your website's user experience. These pages provide an opportunity to maintain a positive relationship with your users, even when things go wrong.
