You need to include “ownProduction” in your values list prior to the annotation.
From: django-users@googlegroups.com [mailto:django-users@googlegroups.com] On Behalf Of Mikkel Kromann Sent: Monday, August 13, 2018 3:22 PM To: Django users Subject: GROUP BY I'm trying to sum the field "ownProduction", grouping it by the foreign key "market" (using the market's human readable name, __name from the Market table) and the week number (which is built-in function __year of the date field "dateContract"). However, when I try to read the results of the query in the last line in the code example below., I get the error: "'dict' object has no attribute 'ownProduction'" So "ownProduction" is to my surprise not a field in the query. What am I doing wrong? contract_query = (Project.objects.all() .filter(department=department_id) .filter(datePipeline__year=year) .filter(stage="WON") .annotate(week=ExtractWeek('dateContract')) .values('week','market__name') .annotate(Sum('ownProduction')) ) for contract_row in contract_query: contract_sum = contract_row.ownProduction It doesn't change anything using .annotate(ownProduction = Sum('ownProduction')) cheers + thanks, Mikkel -- You received this message because you are subscribed to the Google Groups "Django users" group.
