I have a simple django's query set like:

qs = AModel.objects.exclude(state="F").order_by("order")

I'd like to use it as follows:

qs[0:3].update(state='F')
expected = qs[3] # throws error here

But last statement throws: "Cannot update a query once a slice has been taken."

How can I duplicate the query set?
