Post-transaction events in Django

So, at work I’m using Django quite a bit, and I ran into a problem where I need the database transaction to be committed, and then I need to trigger additional server-side code that will act on that data. Putting all of this into the view function with a manually managed transaction sucks, far too […]

Where Django signals aren’t enough

So, I’ve been trying to solve an issue in some Django code at work where Django’s insistence on cascading deletions across foreign keys (not necessarily a bad thing) has resulted in unintended deletion.

Where migration frameworks fail

Django does not yet come with a migration framework to evolve the database schema, so I wrote a really simple one, based on Rails migrations. The system is simple.

Processing a table of forms in Django

I’m using Django for my current web interface work at Mitel, and I’m constantly finding that I have to push the limit of my knowledge in Django to make it work with many of the requirements that I have. One example is instead of displaying a single form for an object in the database, on […]

Django Book PDF

While Django users must certainly be happy that there is a free Django book online, it does not include a downloadable copy. Probably because it’s also gone to print. Luckily, Tane over at Digital Spaghetti has compiled a pdf version that is downloadable. I think the book will sell fine though. I’ve already ordered a […]
