SQLAlchemy: filter by membership in at least one many-to-many related table

Question

Using SQLAlchemy 0.7.1 and a MySQL 5.1 database, I\'ve got a many-to-many relationship set up as follows:

user_groups = Table(\'user_groups\', Base.metadata,         


        

Answer 1

You can use in_:

session.query(ZKUser).filter(ZKGroup.id.in_([1,2])).all()
