SqlAlchemy: filter to match all instead of any values in list?

Question

I want to query a junction table for the value of column aID that matches all values of a list of ids ids=[3,5] in column bID.

Answer 1

Based on @Gordon Linoff answer and with two tables A and B where A has a relation one- to-many towards B called A.bs the SqlAlchemy equivalent would be:

from sqlalchemy import func  
session.query(A).join(B).filter(B.id.in_()).group_by(A.id).having(func.count(A.bs) == len()).all()
