Comment:
I'm not sure what exactly you want to achieve because your expected query
and Django queryset are slightly different, but my understanding is that
`values()` is missing:
{{{
query.annotate(person=Concat('field1',
'field2')).values('person').annotate(Count('person', distinct=True))
}}}
Moreover this is a support question not a bug in Django, please use one of
