Where to put side-effects in the event of a cascade delete.

March 17, 2014

Django's ORM supports the concept of a 'cascade delete' - whereby the deletion of an object via the ORM results in the deletion of its related child object (related via a Foreign Key relationship).

Workflow update

Linking Trello to Git has closed the loop on tracking progress.

February 26, 2014

We've written before about our workflow, and the tools that we use, but one thing that I've also missed from my Fogbugz days is the link between issues and commits.

Since launching YJ we have been running on Django 1.4, and mocking out using the technique outlined in this article:
