only to make users sad because something broke, but knock them out of context becaue django custom 404 our entire design blew up. Luckily, Django makes it incredibly simple to redefine your 500 handler in your URLConf. Most pythonistas know that http://stackoverflow.com/questions/17662928/django-creating-a-custom-500-404-error-page class="pre">import * is a bad thing, but it is standard in the Django community in your URLConf to do a from django.conf.urls.defaults import *. This has the effect of pulling in Django's default handler500 function. So if you want to override Django's default, http://ericholscher.com/blog/2009/sep/23/pretty-django-error-pages/ you simply set it up like so. from django.conf.urls.defaults import * handler500 = 'path.to.my.sweet.views.server_error' Then you simply define a server_error view that renders the error page with a RequestContext. from django.shortcuts import render_to_response from django.template import RequestContext def server_error(request, template_name='500.html'): """ 500 error handler. Templates: `500.html` Context: None """ return render_to_response(template_name, context_instance = RequestContext(request) ) If you're feeling extra special, you can even change the template rendered. Note that you can also do this for the 404 handler by defining a 404handler in your URLConf in the same fashion. Then you can get pretty error pages!

a Django project to production is to create templates for 404 (page not found) and 500 (server error) http://david.feinzeig.com/blog/2012/02/18/tips-for-creating-404-page-not-found-and-500-server-error-templates-in-django-plus-configuring-email-alerts/ errors. You can also setup some error and broken link reporting. Here are a few tips: Where the 404 and 500 templates live The 404.html and 500.html templates live in the root of your templates directory (TEMPLATE_DIRS setting). Creating the 404 template The 404.html template is shown when a page is not found. It is often 500 error a good idea to maintain the overall look and feel of the site even if a piece of content is not found. As it is good practice to use template inheritance with Django's templating system, create a 404.html template that extends your base template. Here is an example: HTML|copycode|?01{% extends "base.html" %}02{% load i18n %}0304{% block title %}Page django 500 error not found{% endblock %}0506{% block content %}07
Page not found
0809Sorry, but the requested page could not be found.
10{% endblock %} Testing the 404 template It is very easy to test your 404.html template. Simply change DEBUG to False in settings.py and try visiting a non-existent URL. Your 404.htmlpage not found template should be served. Creating the 500 template The 500.html template is shown when there is some kind of catastrophic server error. Since you cannot be sure what the root cause of the issue is, you cannot rely upon the entire Django framework being available and should therefore keep it decoupled from everything. A simple HTML file is a good choice. Here is an example: HTML|copycode|?0103040506Page unavailable
1112Sorry, but the requested page is unavailable due to a server hiccup.
