Django : How to write Django Group by and where Condition?

问题

I have Django Model with five fields and I mention two fields in serializer class.I need to perform group by and where ClosingStock>0 condition. I have tried with this query but am not getting output.

StoreClosingStock.objects.filter(CLOSING_STOCK__gte="0").values('ITEM_CODE','CLOSING_STOCK')

I have implemented the same query in mysql its working fine .I want the same output in Django

Views.py

class StoreClosingViewset(viewsets.ModelViewSet):
    serializer_class = StoreClosingStockSerializer


    queryset=StoreClosingStock.objects.filter(CLOSING_STOCK__gte=0).values('ITEM_CODE','CLOSING_STOCK')
#The remaining Fields 
#,'BRAND_NAME','STORE_NAME','STORE_CODE','ITEM_NAME')


    filter_backends = [SearchFilter, OrderingFilter]
    search_fields = ['ITEM_CODE', 'CLOSING_STOCK']
