New description:
Making a query where I can get all of the objects matching a certain list
is quite useful. However, Django currently doesn't allow me to get objects
that DON'T match a list:
`test = ProductPreparation.objects.filter(product=product,
preparation__id__not_in=preparations)`
I feel like adding a field lookup for `__not_in` would be helpful. I've
created a pull request on Github:
https://github.com/django/django/pull/4984
I've not added any tests to it, as I couldn't find any tests for `__in`,
and don't quite know how to test an entire field lookup. Apologies; would
love pointers.
