Hello.
I was unable to reproduce the problem on your test example. I THINK it does
exactly what my problematic code does. It seems that either the problem is more
elaborate (but I don't see it) or I have a bug somewhere in my code. However my
simple workaround works, so I consider the problem
Hello.
I managed to solve my problem. I use session.execute(...) instead of
session.delete(), because the second form deletes more things than it should.
The working code is:
# Move some client products from a duplicate to the original.
# Remove duplicate clients afterwards (in cascade).
there's no mapping or code example provided here, which makes a condition like
this extremely difficult to diagnose, however I've prepared a test script that
takes its best guess as to configuration, that is, a client_products collection
with a client backref, and a cascade of all,
