python - Can you extend SQLAlchemy Query class and use different ones in the same session? -

-

i using sql alchemy orm , have classes/tables each of may have custom queries. let's say, want add table fruit filtering possibility called with_seed giving me fruits seeds, , table cutlery filtering method is_sharp giving me sharp cutlery. want define these filters extensions query object, , want use them in same transaction:

def delete_sharp_cutlery_and_seedy_fruits(session_factory):   session = session_factory()   session.query(fruit).with_seed().delete(synchronize_session='fetch')   session.query(cutlery).is_sharp().delete(synchronize_session='fetch')   session.commit()

is possible?

this related question here. solution there requires different sessions created different query classes.

you can pass session query constructor

customquery(entities=[fruit], session=session).with_seed().delete(synchronize_session='fetch')
