yeah just tell me what youd like to happen here:
mapper(A, a, properties={
'bs':relation(B, cascade="all, delete-orphan")
})
b = B()
sess.save(b)
sess.flush()
versus here:
a = A()
b = B()
sess.save(a)
a.bs.append(b) # does sess.save(b) due to cascade rule
a.bs.remove(b)
sess.flush()
no error in either case ? or just case #1 ? (or a warning in one/
both cases) ? if only an error in case #1, can you see why I'm
uncomfortable with it ? or do list "remove" operations now cascade
as "expunge" operations...and is that a surprise behavior ...
