The problem was in the default ordering. It was specified in the Meta
:
class ChartPoint(models.Model)
...
class Meta:
ordering = ['-date']
Remove the ordering and date
will not be added to the GROUP BY
:
speed_by_computer = ChartPoint.objects.filter(
date__gte=start,
date__lt=end,
).values('computer_id') \
.annotate(hs_avg=Max('speed'))
.order_by()
