Hi, I'm experiencing some possible bug with sqlalchemy here: - I query for some data - Update some data - Make no flush (autoflush is set to False) Then no commit is issued, hence my data is not updated in the database. At least, I looked at the function "tpc_vote" and put some print statement there and self.tx seems to be None, therefore, no commit() is issued. If I do a session.flush() after the updates, the session is perfectly commited. Does anyone know why and what I can do about it?
