If I merge() an object with a collection property, the backref's are
not set as they would be if I had assigned the collection to the
object.
I expected that this should occur. Is there rationale for not setting
backref's or would it be possible to make this change?
Thanks,
Kent

A persistent object doesn't populate an unloaded backref on a forward set
event. This is for efficiency so that when you do something like:
for b in Session.query(B):
b.a = some_a
it doesn't spend time loading the bs collection of some_a, which if you had
a lot of different some_a
