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
