Unless I understand you wrong, this should be all you need: def as_dictionary(self):
song = { "id": self.id, "info": self.info.as_dictionary() } return song > FWIW, I just use a base class / mixin that has this method: class UtilityObject(object): def columns_as_dict(self): return dict((col.name, getattr(self, col.name)) for col in sqlalchemy_orm.class_mapper(self.__class__).mapped_table.c) this will ONLY handle the defined columns in the class -- it will not handle the relationships. You can extend this to handle the relationships using another attribute, though I forget what it is. (If you do a pdb.set_trace() you can just `dir()` the object to find the properties.) But that will give you a dictionary on every object... So then going back to your example, you could just have `custom_dictionary` that handles the columns + a specific relationship def custom_dictionary(self): song = { "id": self.id, "info": self.info.columns_as_dict() } return song > -- You received this message because you are subscribed to the Google Groups "sqlalchemy" group.
