I have this SQL:
SELECT
stock_id, consignment_id, SUM(qty), SUM(cost)
FROM
warehouse_regсonsignmentproduct
WHERE
product_id = '1'
GROUP BY
stock_id, consignment_id
HAVING
SUM(qty) > 0
I used django ORM to create this query:
regСonsignmentProduct.objects
.filter(product='1')
.order_by('period')
.values('stock', 'consignment')
.annotate(total_qty=Sum('qty'), total_cost=Sum('cost'))
.filter(total_qty__gt=0)
But my django query returns an incorrect result.
I think, the problem is in "annotate"
Thanks!
You need to order by the values to force grouping, so:
regСonsignmentProduct.objects.filter(product='1').values(
'stock', 'consignment'
).annotate(
total_qty=Sum('qty'),
total_cost=Sum('cost')
).filter(total_qty__gt=0)
