Try working first with two separate relation()s using a secondary join that filters on "input" or "output" (theres an example of something similar in the docs); then add column_mapped_collection in. Alternatively, use just one relation, and build dict-like proxies on top of it (i.e. class descriptors which return a custom object that has a __getitem__ method, which then reads back to the main relation to get data). This the more manual route but is not terribly complex. A not quite the same thing example of this can be seen at: http://www.sqlalchemy.org/trac/browser/sqlalchemy/trunk/examples/dynamic_dict/dynamic_dict.py . --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "sqlalchemy" group.
