You have to make additional queries since you are using concrete inheritance from your "base" model class.
It might be a little heavy weight for just that one need, but Django polymorphic handles this transparently for you. It is usually my go-to when polymorphic models simplify my work. If you're not getting any more complicated perhaps you can define the relationship field manually and include a nested copy of your child model in the serialized data.
