Migrations
Migrations are used to create and update the database schema. They are run automatically every time Spoolman starts.
To create a new migration, edit the tables as desired in spoolman/database/models.py, then start the Spoolman server to update your local sqlite database.
pdm run python -m spoolman.main
Stop the server once it's up.
Then, let Alembic automatically create a new migration file:
pdm run alembic revision -m "some title" --autogenerate
Go into the created migration and make sure it looks good, that the column changes etc are as desired. Format it with Black and Ruff. Commit.
