I am using MongoDB as underlying DB with Django.
pipeline = {
'price' : Sum('price'),
'month' : ExtractMonth('dateValue'),
}
queryset =
ListingBooks.objects.values('dateValue','typeBook').annotate(**pipeline)
Unfortuantely i get a NotImplementError, as if Djongo ORM i use doesnt
implement this function.
Can anyone hint me on how to keep the grouping by month at this query level
without having to do it manually at the serverside or client side ?
Thank you
Es.
