here are my mappers in case that helps, maybe I don't understand the
cascading properly?
# relations for the bookings
mapper( Booking, booking_table, properties={
'client': relation( Client ),
'institution': relation( Institution, ),
'category': relation( Category ),
'staff_associations': relation(BookingStaffAssoc, lazy=False,
cascade='all, delete-orphan',
order_by=booking_staff_table.c.ordering )
})
# Association mapper, this is the important part!
mapper( BookingStaffAssoc, booking_staff_table,
primary_key=[ booking_staff_table.c.booking_id,
booking_staff_table.c.staff_id],
properties={
'booking' : relation(Booking, lazy=False, cascade='all,
delete-orphan' ),
'staff': relation(Staff, lazy=False, cascade='all, delete-orphan')
})
Thanks!
