on tag:v1.2.5 of master branch, it gets this exception:

InvalidRequestError: No transaction is begun.

I guess it may this:
db_session set autocommit=True, then line 136:db_session.commit()
db_session has automatically run commit

just set autocommit=False , this example runs well

Thank you very much for this!

derp, thanks for the easy googleable fix calling .commit() when autocommit=True
