I have a very simple filter made using DjangoBackendFilter and Ordering filter. It works with all the query parameters such as ?part_number=12345 but when it comes to the id field it does not work at all, i.e. ?id=12345.

I don't have any list filters yet so I do not expect multiple filter values to work. But I do expect every field to work for single value input. Seems strange that only the id field does not work. I have also tried using ?pk=12345 in the API URL but it does not filter anything either.

views.py

class PartList(generics.ListAPIView):
 queryset = Part.objects.all()
 serializer_class = PartSerializer
 pagination_class = StandardResultsSetPagination

 filter_fields = '__all__'
 ordering = 'id'

pagers.py

class StandardResultsSetPagination(PageNumberPagination):
 page_size = 10
 page_size_query_param = 'page_size'
 max_page_size = 1000

 def get_paginated_response(self, data):
 return Response(
 'links': 
 'next': self.get_next_link(),
 'previous': self.get_previous_link()
 ,
 'count': self.page.paginator.count,
 'total_pages': self.page.paginator.num_pages,
 'results': data
 )

serializers.py

class PartSerializer(serializers.ModelSerializer):
 class Meta:
 model = Part
 fields = '__all__'

I figured it out.

The problem was with

filter_fields = '__all__'

This notation includes the id/pk in the serializer but in the filter it does not include id.

So I just replaced it with

filter_fields = [field.name for field in Part._meta.get_fields()]
