Say I have two model classes, one of which is a sub-class of the other: class Place(models.Model): ...
class Restaurant(Place): objects = models.Manager() ... [Note, I'm using model inheritance here, **not** a OneToOneField. The explicit assignment of 'objects' seems to be necessary or Resaurant.objects.all() returns a list of Place objects?!?] Instances of Place will be stored in one table, and instances of Restaurant will be stored in another table. How would I go about implementing an efficient 'extent' query: a QuerySet which would give me an instance of Place for each row in **both** tables? (Or instances of Place or Restaurant as appropriate, but all in one query set.) Ideally, I'd like to be able to say things like: Place.objects.extent() # get all places/restraunts Place.objects.extent().filter(...) # select sub-set across both types etc. The only idea I have so far is to create a composite QuerySet implementation and a custom manager, which sounds like a fair bit of work :-) Is there anything like this already in Django?
