Hi all,
For a given declaratively mapped class in SA 0.6, how do I
programmatically find out all other mapped classes forming a many-to-
one or many-to-many relationship with it? I know I can ask a table

Hi,
Sorry Michael i was unclear on this - i tested on 4 drivers:
psycopg2,
pg8000,
mysql-python (1.2.3c1),
oursql (0.9.2)

mysql driver fails.
the problem is solvable by passing passive_deletes=True, to
That was exactly what I was looking for. Thanks a lot :-)

If you were to use string literals with remote_side here, its the full expression would
be a string, i.e. remote_side=Option.id_. But that's not needed here
