Edit file alembic.ini. You need look at sqlalchemy.url field for bind with DB. And edit file_template field for
creating pretty migration module names
For example:
sqlalchemy.url = postgresql+psycopg2://{db_user}:{db_pass}@{db_host}:{db_port}/{db_name}
file_template = %%(year)d-%%(month).2d-%%(day).2d_%%(rev)s_%%(slug)salembic revision --autogenerate -m "Some message"
How it's work?
You need add your app package to settings.main.APP_MODULES list. Next step is initialization project's alembic with
alembic/env.py and custom function get_project_models_metadata().
Function get_project_models_metadata() append all metadata objects to list for field target_metadata. Target
metadata objects is observed Models to check changes and add new Models.
alembic upgrade head
