Dead simple database migrations using Python.
Flyway is great, but it's seems a bit too heavy for simple projects, especially non-JVM ones.
So I created
It's just a little
pyway.py file, a few dozen lines long.
All it does is run a bunch of SQL files against your database if
it hasn't already, and it keeps track in a little table.
For now, it only supports
sqlite3, but it would be trivial to
extend to any other SQL system that supports running SQL commands
via the command line.
You should be able to pretty easily modify it to suit your needs, and it's liberally licensed so that you can feel free to.
python pyway.py test.db sample_migrations
- Postgres support
- MySQL support
- Add support for transactions around migrations?
