Comment:
Hi Adam,
From the description here it just looks like the expected behaviour, as
per the
[https://docs.djangoproject.com/en/2.2/ref/models/querysets/#django.db.models.query.QuerySet.distinct
various `Note` callouts in the `distinct()` documentation].
(If you really think there's a bug here, can I ask you to narrow it down
to something more specific? What are the exact models and ORM calls in
play. What is the exact SQL generated? Vs What do you expect and why?
Thanks.)
