I added new model, then run
$ pipenv run alembic revision --autogenerate -m "Add new table
TRAVIS_ACTIVE_USERS" --depends-on=<previous-revision>
Then I got this:
INFO [alembic.runtime.migration] Context impl Db2Impl.
INFO [alembic.runtime.migration] Will assume non-transactional DDL.

I got the impression that a new model should NOT depend on existing revision
but no idea why new revision generation failed.
Notice that I used this code in previous model to avoid generating unwanted
primary key:
__mapper_args__ = {
'primary_key': [email, dt_month]
}
