Dave - I think you are having the same problem I had to begin with.
Using the ORM means you have to change your way of thinking.
Remember - the ORM isn't perfect, and there are instances where you either
need to use a raw SQL, or split the query up into multiple calls. In some
cases, doing things the 'right' way is actually the 'wrong' way, depending
on the data you are dealing with, and your indexes.
Put simply - Django does have, nor need, a 'group by' method - and if you
believe otherwise, it's because you haven't got used to the "Django
methology" yet.
Just my two cents worth.
