Whoops, my `==` got erased, it should read:
> db.session.query(Images)\
> .join(VideoClip,
> Images.video_clip_id == VideoClip.id
> )\

>> I am explicitly providing the on-clause arguments, but that is not
necessary for configured relationships ( see
https://docs.sqlalchemy.org/en/13/orm/query.html#sqlalchemy.orm.query.Query.join
)
When using `join()` and configured relationships, if you are not filtering
on that relationship you may want to use the
`.options(contains_eager('relationship))` construct (see
https://docs.sqlalchemy.org/en/13/orm/loading_relationships.html#sqlalchemy.orm.contains_eager
)
