The only thing I see that ties us to sqlalchemy is using the model objects directly. But I think there are actually three choices here: sqlalchemy objects, dicts, and regular objects. Well really there are four, if we include sqlalchemy objects that try to act like dicts :-). My preference order is:
1. regular objects (which is what I thought Kevin was talking about. . . maybe?) 2. regular dicts 3. a tie between sqlalchemy objects and sqlalchemy objects that try to behave like dicts "Devin Carlen" <[email protected]> said: > Matt, that answer is simple: so we can use things other than sqlalchemy. > > > > On Dec 15, 2011, at 10:35 AM, Matt Dietz wrote: > >> I have to confess to being confused here.
