I’m encountering an issue with my custom 404 page rendering functionality in Django. Despite setting up the necessary components, the custom 404 page is not being displayed when a page is not found. Here’s an overview of my setup:
404 Template (error404.html):
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<title>Page Not Found</title>
</head>
<body>
<h1>404 - Page Not Found</h1>
<p>The page you are looking for does not exist.</p>
<p>Tommy the train!</p>
</body>
</html>
404 Template Render View (custom_404_view):
from django.shortcuts import render
def custom_404_view(request, exception):
return render(request, 'home1/error404.html', status=404)
URL Configuration (urls.py):
handler404 = 'home1.views.custom_404_view'
Settings:
ALLOWED_HOSTS = ['localhost', '127.0.0.1', '::1']
DEBUG = True
Despite configuring everything as mentioned above, the custom 404 page does not appear when a page is not found. I’ve ensured that DEBUG is set to True in my settings. Can anyone spot what might be causing the issue or suggest any additional troubleshooting steps?
I attempted to implement custom 404 page rendering functionality in Django by following the steps outlined in my question. Here’s a summary of what I tried and what I expected to happen:
-
Implemented 404 Template: I created a custom HTML template named
error404.htmlcontaining the necessary markup for a 404 error page. -
Defined Custom 404 View: I defined a view function named
custom_404_viewin my Django application (home1.views) to render the custom 404 template when a page is not found. -
Configured URL Handler: I configured the
handler404variable in myurls.pyfile to point to the custom 404 view. -
Checked Settings: I verified that the
DEBUGsetting in my Django project’s settings file is set toTrue, and also ensured that myALLOWED_HOSTSincludes the necessary values.
Expectation: I expected that when a page is not found (e.g., accessing a non-existent URL), Django would render my custom 404 page (error404.html) instead of the default 404 page.
Actual Result: Despite following the above steps and ensuring that all configurations are correct, the custom 404 page is not being displayed when a page is not found. Instead, the default Django 404 page is shown.
