How can I update my filter function to work generically?
I overrode the SAVE function in one of my models, and now I want to put it in a MIXIN to be used by other models. But I have one part I'm not sure how to make generic.

Pagination with annotated prefetch data
I wanted to speed up the API, so i had added pagination with annotations to get a count of a certain data. The problem with the prefetched annotated data is that it doesn't consider the pagination and if there are 1000 records it'll prefetch the data for annotation of 1000 records even if i want only 10 records in the first page.Is there a way to prefetch data to work with pagination? class ListCourseAssignments(generics.ListAPIView): serializer_class = AssignmentModuleSerializer pagination_class = SetByTenPagination filter_backends = [filters.SearchFilter] search_fields = ['name'] permission_classes = [ permissions.IsAuthenticated, CreateAssignmentPermission] def get_queryset(self): active_statuss = [EnrolmentStatusValues.APPROVED.value, EnrolmentStatusValues.WITHDRAW_PENDING.value] now = timezone.now() assignments = SimpleAssignmentModule.objects.filter( course_share_item__course__id=self.kwargs.get('pk')) unit = self.request.query_params.get('unit') if unit: assignments_in_unit = CourseShareItemModule.objects.filter(module__in=assignments.values_list( "id", flat=True), group__id=unit).select_related('module').values_list("module__id", flat=True) assignments = assignments.filter(id__in=assignments_in_unit) assignments = assignments.annotate( subject_id=Subquery(SimpleAssignmentModule.objects.filter(id=OuterRef('id')).only('id').annotate( subject_name=F('course_share_item__course__id')).values('course_share_item__course__id')[:1]), unit_id=Subquery(CourseShareItemModule.objects.filter(module__id=OuterRef('id'), course_share_item=OuterRef( 'course_share_item')).only('id').annotate(unit_name=F('group__id')).values('group__id')[:1]), subject_name=Subquery(SimpleAssignmentModule.objects.filter(id=OuterRef('id')).only('id').annotate( subject_name=F('course_share_item__name')).values('course_share_item__name')[:1]), unit_name=Subquery(CourseShareItemModule.objects.filter(module__id=OuterRef('id'), course_share_item=OuterRef( 'course_share_item')).only('id').annotate(unit_name=F('group__name')).values('group__name')[:1]), submitted_count= SQCount( AssignmentModuleProgress.objects.filter( Q(module_progress__module_progress_course_progresses__course_progress_userenrolments__expiry_date__isnull=True) | Q( module_progress__module_progress_course_progresses__course_progress_userenrolments__expiry_date__gt=now), module_progress__module_progress_course_progresses__course_progress_userenrolments__deleted=False, module_progress__module_progress_course_progresses__course_progress_userenrolments__user__is_suspended=False, module_progress__module_progress_course_progresses__course_progress_userenrolments__user__tenant__is_suspended=False, module_progress__module_progress_course_progresses__course_progress_userenrolments__status__short_name__in=active_statuss, module_progress__module__id=OuterRef('id'), is_submitted=True, ).values( 'module_progress__module_progress_course_progresses__course_progress_userenrolments').distinct() ), to_grade_count= SQCount( AssignmentModuleProgress.objects.filter( Q(module_progress__module_progress_course_progresses__course_progress_userenrolments__expiry_date__isnull=True) | Q( module_progress__module_progress_course_progresses__course_progress_userenrolments__expiry_date__gt=now), module_progress__module_progress_course_progresses__course_progress_userenrolments__deleted=False, module_progress__module_progress_course_progresses__course_progress_userenrolments__user__is_suspended=False, module_progress__module_progress_course_progresses__course_progress_userenrolments__user__tenant__is_suspended=False, module_progress__module_progress_course_progresses__course_progress_userenrolments__status__short_name__in=active_statuss, module_progress__module__id=OuterRef('id'), is_submitted=True, score=None ).values( 'module_progress__module_progress_course_progresses__course_progress_userenrolments').distinct() ) ) return assignments.order_by(F('due_date').asc(nulls_last=True)) -

How to correctly enforce field combination in another table (Django)?
