usage
scripts: bafser
Both bafser and python -m bafser load .env from the current working
directory before running a command. Existing environment variables take
precedence; a missing .env is allowed. Parent directories are not searched.
For example, DBPATH in .env supplies a configuration value declared as
db_path = "ENV:DBPATH". This loading applies to CLI commands; application
entry points must load their own .env if needed.
init project: bafser init_project (existing generated files are kept; use --force to replace them)
With use_alembic = True, create an initial migration before starting the app:
bafser alembic revision followed by bafser alembic upgrade.
run gunicorn -w 4 --threads 2 --worker-class gthread -b 0.0.0.0:80 main:app
or manually
copy bafser_config.example.py to project root as bafser_config.py

Mixins also provide get, query, and all. They use the request session by
default; pass db_sess when working outside a request or within a specific
transaction:
item = SomeTable.get(item_id)
item = SomeTable.get(item_id, db_sess=session, for_update=True)
items = SomeTable.all(db_sess=session)
