Comment:
> Using Q as rhs value in filter...
Sorry, this is just a misuse of `Q`. A `Q` represents the expression, not
just the rhs (or lhs).
Look at [https://docs.djangoproject.com/en/3.0/topics/db/queries/#complex-
lookups-with-q the examples from the docs]:
`Q(question__startswith='What')`.
So in your case you need `A.objects.filter(Q())` (not `pk=Q()`)
Please use support channels if you have further queries.
