The only thing I really want is a good and easy way to use SQLAlchemy to manage a change-set as well for my schema so that I can upgrade/downgrade at will. Something like what Rails has built-in would be awesome.
Is something like that already out there? Something that works well and can easily be integrated into a project?
There's SQLAlchemy-Migrate as someone mentioned, and I've also recently released Alembic (https://bitbucket.org/zzzeek/alembic) which is already being used in some production environments. Alembic includes semi-automatic version generation in a similar way as South for Django does.
