My django projects that form this site are not finished. I change them every now and then. This includes the underlying data models.
One thing you have to know when you do this, is that django's "manage.py syncdb" does not update already existing database tables. That is up to you! If you're like me use the sqlite3 database that is included in Python2.5, then you might also be interested in this project:
sqlitebrowser.
At least I don't care enough about sql to really learn it, and then a gui like this comes very handy.
