I really like the idea of how to create those urls. Once I have extracted the name and type from the url, do I retrieve my Pet object like the following:
current_pet = Pet.objects.get(name__iexact=name, type__iexact=type) If my table has 1000s of pets, isn't the above a bit slow when compared to the retrieving a pet by id? How is this kind of situation handle in some of the Django web application out there?
