Ok, thanks. This is a beefy one so that will be extremely tricky to
extract. I had hoped that the combo of lazy+joined would have been a
clear indicator since they are opposite loading strategies.
the word "lazy" there is the name of the field. It is the internal
equivalent to the "lazy" argument on relationship:
http://docs.sqlalchemy.org/en/rel_1_0/orm/relationship_api.html?highlight=relationship#sqlalchemy.orm.relationship.params.lazy
that said, here is exactly what will cause your error. Any of the
attribute names "defined_items", "child_product" or "number" are not in
fact bound to a relationship(), and instead refer to a Column-mapped
attribute. Looks a lot like "number" here is a Column. Is that the
case? You can't call joinedload for a column attribute.
