So the idea is a django orm database migration system that:
- Is simple.
- Doesn't make you use sql. This is an orm, we shouldn't have to use sql.
- Can be automatic. Predicts the migration script for you so you don't have to think about what has changed.
- Works well in a version control system, or even distributed ones. Because damnit.
- During the migration process, allows you to use the state of your previous models as if they were still there. This is key, and is not done anywhere else, as far as I know.
Currently tests are passing on mysql, postgresql_psycopg2, and sqlite3.
