I think one approach that you might consider is a "subclassing queryset". Basically, it allows you to query the parent model and it will return instances of the child models in the result queryset. It would let you do queries like:

models.service.objects.all() 

and have it return to you results like the following:

[ , , , ...]

For some examples on how to do this, check out the links on the blog post linked below.

However, if you use this approach, you shouldn't declare your service model as abstract as you do in the example. Granted, you will be introducing an extra join, but overall I've found the subclassing queryset to work pretty well for returning a mixed set of objects in a queryset.

Anyway, hope this helps, Joe
