Finally, Django 1.0 is released!

After countless hours of hard work by many talented people, it is a pleasure to see the long-awaited version 1.0 released to the world. Finally, a version number that reflects the quality of the codebase, which in fact I have been using in production for many months.

New features that I am excited about include:

Re-factored admin application

Developed under the newforms-admin branch for a long while, the re-factored admin application is much more customisable and means I don't have to do so many ugly hacks and workarounds any more. See the admin reference for details.

Re-factored ORM

The internals of the ORM were pretty much rewritten from scratch in the queryset-refactor branch, resulting in many annoying bugs being fixed. This also includes support for model inheritance, which allows for more elegant models. See the wiki for more details.

Have fun!

DebugFooter is a handy little piece of middleware that Simon mentioned during his talk on Monday.

Adds a hidden footer to the bottom of every text/html page containing a list of SQL queries executed and templates that were loaded (including their full filesystem path to help debug complex template loading scenarios).

To use, drop in to a file called 'debug_middleware.py' on your Python path and add 'debug_middleware.DebugFooter' to your MIDDLEWARE_CLASSES setting.

This simple Django snippet demonstrates how to ping Technorati and Google when a blog post has been added or updated.

import xmlrpclib

from django.core import urlresolvers
from django.db.models import signals
from django.dispatch import dispatcher

from django.contrib.sites.models import Site

def send_pings(sender, instance):
    base_url = 'http://%s' % Site.objects.get_current().domain
    blog_url = '%s%s' % (base_url, urlresolvers.reverse('blog-index'))
    entry_url = '%s%s' % (base_url, instance.get_absolute_url())
    # Ping Technorati
    j = xmlrpclib.Server('http://rpc.technorati.com/rpc/ping')
    reply = j.weblogUpdates.ping('Jason Davies', entry_url)
    # Ping Google Blog Search
    j = xmlrpclib.Server('http://blogsearch.google.com/ping/RPC2')
    reply = j.weblogUpdates.ping('Jason Davies', blog_url, entry_url)

dispatcher.connect(send_pings, sender=Entry, signal=signals.post_save)
