Hi all,
I'm sorry, as I feel like this is kind of a beginner question. I'd expect
that when I set a column attribute the respective relationship field would
change or at least be marked as changed (so a posterior access can be
loaded later on another access), but I've found a case where it
Hi,
When you go through the objects, do you remove them from the session with
session.expire(obj)?
Hope this helps,

Hi,
I'm not sure this is supported or intended to work, but I'm trying to use a
value inside a JSONB field in a relationship.
class Department(DeclarativeBase):
__tablename__ = "department"
department_id = Column(Integer, autoincrement=True, primary_key=True)
class Project(DeclarativeBase):
the previous situation where it silently lost one of the updates, but
slightly worst than the update with synchronize_session if it would work
with inheritance). I'm assuming there's no other alternative?
Thanks in advance,
João

Hi,
I have a situation where an update tries to update the wrong table on when
a column comes from the parent table and is not on the current table. I'll
grant I didn't quite understand all the caveats in
