So at the very least, you want to be using the "association object" pattern described at http://www.sqlalchemy.org/ docs/04/mappers.html#advdatamapping_relation_patterns_association . but beyond that, it seems like youre trying to do a polymorphic association. This isnt a built-in feature of SA but I do have a blog entry describing both ActiveRecord's approach (sort of like what youre doing here) as well as a version that maintains referential integrity: http://techspot.zzzeek.org/?p=13 . - mike --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "sqlalchemy" group.
