Django External Schema Evolution Branch

Django, via the command ./manage syncdb, can automatically build a database schema based on your applications models.py file. However, after you've done this once, it leaves you with two unpleasant follow-up options if you ever make any changes to your model structure:

1. destroy your existing schema (along with all your data) and let ./manage syncdb rebuild it for you
2. manage your own schema upgrades by writing your own SQL

Project deseb aims to fill this void by providing s third option:

1. generate schema upgrades via the command: ./manage evolvedb

Installation Instructions

1. cd into your project directory (where your manage.py is) or anywhere in your PYTHON_PATH
2. run: svn checkout http://deseb.googlecode.com/svn/trunk/src/deseb
3. add import deseb to the top of settings.py

Using deseb

1. make modifications to your models.py (either a new or existing project)
2. run ./manage evolvedb
3. lather, rinse, repeat

Look at usage and a sample run.
