self.begin() is called inside the __init__ method of the Session when autocommit is at the default of False. the reason you can't call it yourself with autocommit=False is that the Session keeps calling it automatically within each rollback() and commit(). which might seem weird but the SessionTransaction doesn't use any database resources for begin(), it's just a logical boundary. > > cheers, > > Chris > > -- > SQLAlchemy - > The Python SQL Toolkit and Object Relational Mapper > > http://www.sqlalchemy.org/ > > To post example code, please provide an MCVE: Minimal, Complete, and > Verifiable Example.
