If I have an object which can be created via either Foo(bar_id=3) or Foo(bar=Bar()), I'd like to have a way to inspect and manipulate it after references have been resolved (such that bar_id is available whether initial specification was via bar or bar_id) but before commit to the database.
Does such a mechanism exist? If not, where would I look at implementing it? I suppose that such hooks could be added by a MapperExtension if they don't already exist, but I'd like to know that I'm not overlooking something obvious beforehand. Thanks! _______________________________________________ Sqlalchemy-users mailing list Sqlalchemy-users@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/sqlalchemy-users
