Hi all.
I just stumbled across an after_attach event handler in my code. That
handler used to replace a None reference with a persistent instance that
was already loaded.
After a few changes, it ended up doing a query to load that instance. It
seems this messes up the session state, which caused a query to change
from
INSERT INTO group_items (group_id, item_id, item_order) VALUES (?, ?, ?)
(242, 244, 0)
into the less usefull
INSERT INTO group_items (group_id, item_id, item_order) VALUES (?, ?, ?)
(None, None, None)
Both the group and the item where created correctly so I ended up with a
database which has all the data, just missing their relationships ;-)
I reverted to running the query when first connecting to the database.
What I would like to know: Is it officially impossible to run queries
from session events? What session functionality is usable from within
session events? (I know that session.{dirty, new, deleted} works fine).
Thanks and happy holidays,
Torsten
