#11671 closed Bug (wontfix)

Aggregations add extra values to ValuesQuerySets :: another usecase

Looking at #10132 I see a similar complaint, however, in this case... the variable is not included in the values/group_by but is annotated.

>>> qs = TblCdr.objects.extra(select={'billable':'IF(billsec=0,0,1)'},).values('network').annotate(Sum('billable')
... )

don't know, but i think i have the same problem #13363. the exception is very similar.

is it complex to create a patch for this, or is it just something nobody did yet?

Patching this would be very helpfull as, this feature would be usefull in clustering (geodjango)

e.objects.extra(select={'cluster':'substring(mortons_code for 10)'}).annotate(objects_in_cluster=Count('cluster')).order_by('objects_in_cluster')

same error:

FieldError: Cannot resolve keyword 'cluster' into field. Choices are:
