Comment (by Hasan Ramezani):
Mariusz,
When I try to run the
[https://code.djangoproject.com/timeline?from=2021-01-05T00%3A49%3A56-06%3A00&precision=second
tests] that you added to the ticket, I get
`ValueError('Index.fields must be a list or tuple.')`
it means currently, `models.Index` doesn't support `models.F('height') /
(models.F('weight__abs') + models.Value(5))` and
`Lower('missing_field').desc()` as index `fields`.
Should we add support for these kinds of fields to `models.Index`?
