{{{
class Foo(models.Model):
name = models.TextField()
type = models.TextField()
class Meta:
ordering = ["name",]
Foo.objects.all().values("type").annotate(models.Count("name"))
}}}
The above code fails to generate the expected result without adding
{{{.order_by()}}} to the query set.
Ticket #10574 called this fixed with documentation, but indicated a proper
fix would be preferred once backwards compatibility wasn't an issue. Lest
this fall off the radar for being closed, I am putting this ticket in for
2.0.
