Description (last modified by eloktev)

Hello,
Using aggregation methods with models, that have set 'ordering' in Meta subclass fails:

class M1 (models.Model)
    date = models.DateField()
    smth = models.IntegerField()    

    class Meta:
        ordeing = 'smth'

count_by_day_qs = M1.objects.values('date').annotate(c=models.Count('id')).values('date', 'c')

#Executes following query:
SELECT "m1"."date", COUNT("m1"."id") AS "c" FROM "m1" GROUP BY "m1"."date", "m1"."smth"
