Wow, thanks for such a fast response! I used the env.py script from
here:
https://github.com/inklesspen/pyramid_alembic_mako/blob/master/pyramid_alembic/alembic/%2Bpackage%2B/alembic/env.py_tmpl
Line 15:
> engine = engine_from_config(config.get_section('app:main'), 'sqlalchemy.')
>
Then in run_migrations_online():

...
> context.configure(
> connection=connection,
> target_metadata=target_metadata

However, once I have the context set up with a connection, I can't figure
out how to retrieve it in a version script.
Thanks,
Ryan
