How do you join nested queries in Django
I am trying to frame a Django query for a normal sql that looks like this: SELECT d.id, sum(d.assess), sum(d.view) from (SELECT id, name, group_concat(status) as group, CASE WHEN(GROUP_CONCAT(status) = 4 THEN 1 ELSE NULL) as assess, CASE WHEN(GROUP_CONCAT(status) = 5 THEN 1 ELSE NULL) as view FROM <tables> Group by id,name) d join <table> e on e.id = d.related_id GROUP BY 1; The inner query (the one that does the GROUP_CONCAT) can be formed using a Django Queryset but Im not able to use that output as a Nested Query so that I can join with the main table. Since GROUP_CONCAT is already an aggregate function(which is implemented in Django using annotate functions), I am not able to do another annotate on those fields. This would avoid doing the outer query but understand why its not possible as you cannot do a GROUPING on a GROUP. I wanted to find out if there is a way to do the above, basically running a queryset as a JOIN Table so it can be used as in the setup above. I have tried: a) Subquery: Dint work as my inner query returns multiple rows (one Group_concat for each grouping) so it … -

Django Rest Framework: How to randomize Queryset while keeping the pagination and search functionality?
Premise: Imagine I have 100 items in the database and each time the user opens the application I want to display 10 random items, and as the user scrolls down more items get added. I started by creating a "ListAPIView" using a "PageNumberPagination" class: class ItemListView(generics.ListAPIView): queryset = Item.objects.all() serializer_class = ItemListSerializer pagination_class = ItemListPagination class ItemListPagination(PageNumberPagination): page_size = 20 This will give me always the same 10 items, so to randomize it I overwrote the "get_queryset" method and used a seed to randomize the queryset. class ItemListView(generics.ListAPIView): serializer_class = ItemListSerializer pagination_class = ItemListPagination def get_queryset(self): objects = list(Item.objects.all()) seed = self.request.GET.get('seed') # get the seed from the request query params random.seed(seed) # set seed random.shuffle(objects) # randomize objects random.seed() # reset seed return objects This works as expected but as soon as I introduce the SearchFilter backend, it errors out because is expecting a QuerySet and not a list. class ItemListView(generics.ListAPIView): serializer_class = ItemListSerializer pagination_class = ItemListPagination filter_backends = [SearchFilter] search_fields = ['name'] def get_queryset(self): objects = list(Item.objects.all()) # Get queryset and convert it to list seed = self.request.GET.get('seed') # get the seed from the request query params random.seed(seed) # set seed random.shuffle(objects) # randomize objects random.seed() # reset … -
