sqlalchemy-migrate does not find change file for version

I am evaluating SQLAlchemy-migrate as a database migration tool. My db_version is 0, and the repository version is 1.



$ python manage.py db_version --url=postgresql://localhost:5432/my_db

0



$ python manage.py version

1


and I only have one unapplied version:



./versions/001_initial_schema_postgres_upgrade.sql



I run the migration tool, but it won't upgrade because it can't find the version:



$ python manage.py upgrade --version 1 --url=postgresql://localhost:5432/my_db



"There is no script for %d version" % self.version

AssertionError: There is no script for 1 version


Am I doing something wrong so that the migrate tool can't find my change script?






python sqlalchemy sqlalchemy-migrate

    I know that this isn't answering your question, but I haven't used SQLAlchemy-migrate and so I thought I'd have a look at the source. It doesn't seem to be very actively maintained (e.g. latest python they have tested on is 3.4 which was released in 2014). If you are just learning and want to try something more actively maintained try alembic which is another sqlalchemy based migration tool. If you need/prefer to use sqlalchemy-migrate then feel free to disregard!
