SqlAlchemy returns "column" results as a `KeyedTuple`. It's similar to
`collections.namedtuple` in the standard library
Looking at your code, my guess is that you had something like this:
ids = session.query(Model.id).filter(...).all()
and are then passing those ids into a query like this:
objects = session.query(Model).filter(Model.id.in_(ids)).all()
if that's the case, your code needs to look like this:
# sqlalchemy returns a tuple on column queries, even for 1 item
results = session.query(Model.id).filter(...).all()
# grab the first element of each tuple
ids = [i[0] for i in results]
# now you have Integers to work with
objects = session.query(Model).filter(Model.id.in_(ids)).all()
