sure, implement before_commit() and put a token inside of session.info - then implement after_flush and look for that token. you can pop the token out there as well but you'd need to be mindful of error handling, perhaps also pop the token out using after_transaction_end. > > -- > 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.
