Hi, Regarding to the discussion some days ago with the SQLAlchemy Zope3 integration, I still have problems with retrieving the session. I currently use a utility for the engine, which seems to work well. However, for retrieving the session, I tried to use the following pattern (many thanks to Michael Bayer, btw.): -------- database module ----------- SASession = scoped_session(sessionmaker( transactional = True, autoflush = True, extension = ZopeTransactionExtension())) def getSASession(): SASession.remove() engine = getUtility(ISAEngineUtility).getEngine() s = SASession() s.bind = engine return s -------------------------------------------- In my application, I then use getSASession() to retrieve my session. However, what I think is not that beautiful is the "s.bind = engine" part. Are there any suggestions how to improve this?
