Hi, Is there a way to get/retrieve the parent object from a collection class's append/add method ? >From the method, call im_self to get the collection object itself, then use collection_adapter ( http://docs.sqlalchemy.org/en/latest/orm/collections.html?highlight=collection_adapter#sqlalchemy.orm.collections.collection_adapter ) to get the CollectionAdapter, then call adapter.owner_state.obj(). I'd recommend passing the parent object around in the first place, however as the above is esoteric and also runs the chance of failing if the parent object has been garbage collected. -- 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.
