DjangoRestFramework - 如何使用“pk”过滤列表？

Question

I want to filter a list of BatchLog objects according to pk that I send through the request - which is their batch_id . Is there a way to access it on views.py file?

I have this in my urls.py file

path('feed/<int:pk>', GetFeedItemView.as_view())

And in my views.py file I want to access a BatchLog object by filtering its batch_id

class GetFeedItemView(RetrieveAPIView):
    serializer_class = FeedSerializer

    def get_queryset(self):
        return BatchLog.objects.filter(batch_id=self.request.pk)

This filter(batch_id=self.request.pk) doesn't work but I want to implement it in the same logic.

How can I achieve this?

Thanks a lot.

You can use self.kwargs["pk"]

class GetFeedItemView(RetrieveAPIView):
    serializer_class = FeedSerializer

    def get_queryset(self):
        return BatchLog.objects.filter()
