The Django web framework.
2008
Multiple inheritance of newforms and modelforms. If you ever see “Error when calling the metaclass bases metaclass conflict: the metaclass of a derived class must be a (non-strict) subclass of the metaclasses of all its bases” when trying multiple inheritance with newforms and modelforms, here’s a scary solution I found.
Sharedance (via) “Sharedance is a high-performance server that centralize ephemeral key/data pairs on remote hosts, without the overhead and the complexity of an SQL database.”—ideally suited to session data, which is a poor fit for a full relational database.
Active on IRC in the past hour. New Django People feature in collaboration with Brian Rosner—DjangoBot now provides information on currently active IRC participants. There’s an opt-out privacy control and the bot sends you a message about it the first time it logs your activity.
django-rosetta—Google Code. Very classy Django-powered interface for both reading and writing your project’s gettext catalog files, hence allowing application translators to work through a web interface.
Google App Engine for developers. Best in-depth coverage so far, from Niall Kennedy. I didn’t know that Guido had worked on the Django compatibility layer.
The Google App Engine model class, db.Model, is not the same as the model class used by Django. As a result, you cannot directly use the Django forms framework with Google App Engine. However, Google App Engine includes a module, db.djangoforms, which casts between the datastore models used with Google App Engine and the Django models specification. In most cases, you can use db.djangoforms.ModelForm in the same manner as the Django framework.
Running Django on Google App Engine. Django 0.96 is included, but you need to disable the ORM related parts and use the Google App Engine Bigtable interface instead.
Why the webstandards world appears to be choosing Django. I’m not convinced that this is a definite trend, but it certainly makes for an interesting discussion.
Django Development with Djblets. The Review Board team have extracted a library of useful Django utilities from their application. The first to be documented are helpers for reducing boilerplate in custom template tags.
Exposing calendar events using iCalendar in Django. A simple abstraction around the vobject Python library.
xPyUnit: Uniting in Python with XML reporting. Should be just the ticket for integrating Django’s testing framework with Cruise Control.
Setup mod_wsgi for Django and Shared Hosting. Tutorial by David Cramer; attached are useful comments from mod_wsgi author Graham Dumpleton.
FormWizard: multiple-step forms in Django. Available in recent trunk versions.
Djangofriendly (via) Ryan Berg’s attractive new site collecting ratings and reviews for web hosts that support Django. I’m still happily hosted on a bytemark VPS, which isn’t currently listed on the site.
Better Use of Newforms. Two really neat techniques: using an inclusion tag template to DRY your custom form templates, and adding what-to-do-next methods to the form class itself to cut down on the application code in your views.
views.py for wikinear.com (via) I’ve published the views.py file from wikinear.com as an example of simple Fire Eagle integration with a Django application.
wikinear.com, OAuth and Fire Eagle
I’m pleased to announce wikinear.com. It’s a simple site that does just one thing: show you a list of the five Wikipedia pages that are geographically closest to your current location. It’s designed (or not-designed) to be used mainly from mobile phones.
[... 1,190 words]Version 2.0 of mod_wsgi is now available. Includes features that should make Python (and Django) on shared hosting much easier: a non-root user can touch their WSGI script file to restart just their application’s daemon processes when they make changes and Python virtual environments are supported to allow different versions of packages without interference.
mysql_cluster (via) My Russian isn’t all that good, but this looks like a neat way of getting Django to talk to a master/slave setup, written by Ivan Sagalaev. UPDATE: English docs are linked from the comments.
Simple Exception Response for AJAX debugging. Neat solution to the problem of Django error pages showing up as raw HTML in the Firebug Ajax log.
IronPython, MS SQL, and PEP 249. How Dino Viehland got Django’s ORM to talk to the .NET database layer.
Queryset Implementation. Malcolm explains the work that has gone in to the queryset-refactor branch. Executive summary: Python’s ORM is probably a lot better at SQL than you are.
Integrating reCAPTCHA with Django. Looks pretty straight forward.
Hacking Contributed Models. Neat Django trick using monkeypatching to make some minor tweaks to built-in contributed models such as auth or flatpages.
In-Depth django-sphinx Tutorial. Another neat Django extension from the guys at Curse: easy integration with the sphinx full text search engine.
queryset-refactor changeset 7126. Malcolm just checked model inheritance in to the queryset-refactor branch, with full documentation and unit tests. People have been requesting this for ages.
themaneater.com Launch. The Maneater’s online edition is where Adrian cut his web development teeth, so it’s great to see them up and running on Django. Important to note that KeepAlive can completely murder Apache/Django performance.
mydeco. Major new Django-powered start-up has launched, based in London.
Django San Diego. A real-life meeting of Django developers in San Diego, as a direct result of profiles on djangopeople.net. Victory!
Python Web Framework on the JVM. An update on both Jython and the Django on Jython project—it looks like Jython 2.5 isn’t that far away.
