I did something like that recently: ----------------- from sqlalchemy import types import simplejson class JsonString(types.TypeDecorator): impl = types.String def process_result_value(self, value, dialect): if value is None: return None else: return simplejson.loads(value) def process_bind_param(self, value, dialect): if value is None: return None else: return simplejson.dumps(value) ----------------- []s Roger --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "sqlalchemy" group.
