In Django 3.2 the ORM looses Meta.ordering default order when .annotate is used

[Pieter Zieschang]

Hi,
I've upgraded from 2.2 to 3.2.15 and now default ordering specified in the Model does not work anymore if i annotate the QuerySet.
I suspect this is a ORM Bug, as the ordering / default order is not in the query anymore since the update to 3.2.

Product class:

class Product(models.Model):
...
    class Meta:
        ordering = ["name"]

Default ordering is working nicely without annotate ... see ORDER BY

>>> print(Product.objects.all().select_related("category").query)
SELECT "memberapp_product"."id",  [...] FROM "memberapp_product" INNER JOIN "memberapp_productcategory" ON ("memberapp_product"."category_id" = "memberapp_productcategory"."id")  ORDER BY "memberapp_product"."name" ASC 

but not anymore when annotate (with a special sum) is used - no ORDER BY anymore in the query:

>>> print(Product.objects.all().select_related("category").annotate(**kwargs).query)
SELECT "memberapp_product"."id", [...]  LEFT OUTER JOIN "memberapp_appointment" ON ("memberapp_appointmentattendee"."appointment_id" = "memberapp_appointment"."id") INNER JOIN "memberapp_productcategory" ON ("memberapp_product"."category_id" = "memberapp_productcategory"."id") GROUP BY "memberapp_product"."id", "memberapp_productcategory"."id"

Since it's been working before i would expect something in the ORM looses the order by in complex queries using annotate.

Thanks for looking into this.
