That seems to help. I'll make an issue for it.

OK then please report this as a bug in sqlalchemy-utils
right now they are not looking at local table
looking at the code here:
https://sqlalchemy-utils.readthedocs.io/en/latest/_modules/sqlalchemy_utils/functions/orm.html#get_mapper
code can be like:
mappers = [
mapper for
It's from sqlalchemy_utils -

AnnotatedTable doesn't have a mapper so I call:
get_mapper(annotated_table_object_here)
To then map a column name to a column on a model with _entity_descriptor.
In get_mapper this seems to hit the "if isinstance(mixed, sa.Table):"
branch and:
if mixed in mapper.tables
ends true to all 3 of the
I would need to see what get_mapper() is doing. the best way to associate the
relevant table to a mapper is to look at inspect(Class).mapper.local_table.

I'm updating "sqlalchemy_django_query" for SQLAlchemy 1.4 and aside of that
I found a peculiar problem - when I call get_mapper on a table
(AnnotatedTable) I get a ValueError due to multiple mappers found.
The model is inherited by two other models and get_mapper finds mappers for
all 3 models
