Hello,
Is below the way to reconnect to postgresql server automatically?
everytime I need to remake a session with
"Session = sessionmaker(bind=engine)
session = Session()"
, is this right?
the codes below can work, but if I don't remake the session, it will failed
at server timeout.

I can't give you much detail except to say the unique object recipe is
doing an .add() when it finds an identity that isn't taken, if you
don't want those persisted then take out the part of the recipe doing
add(). However, you'd need to alter the recipe further such that if
the program asks for t
Demitri, any plans (or previous attempts) to integrate this into SQLAlchemy
proper?

The update and delete methods on query are for performance optimization and
potentially for atomicity in some situations, and thus dont assume much
about how the UPDATE should proceed. Adding the discriminator for simple
cases is not that hard to implement but would be backwards incompatible and

Last copy paste went wrong.
The uniqueness is ensured by:

Dear Mike,
thank you for the fast response as usual.
Your comment made me think. Actually I was not adding things in the session
directly. I revised my code and I believe the behaviour I'm describing is
related to the application of the UniqueObject patter described in the
documentation.
