As of the merge of qsrf, this will also work:
total = sum(Model.objects.values_list('amount', flat=True))
Plus there's the SoC project which will be building high-level
aggregate support over the summer; for now the above solution isn't so
bad for performance (sum() is done in C with some neat optimizations,
if you ever look at the code). And, of course, you can always drop
down to raw SQL and feed a SELECT SUM directly to the DB.
