Not being able to represent array serializer in get_serializer_class so OpenAPI schema is generated nicely

[hnykda]

Hey (copied from here as I didn't notice the info about starting a discussion first).

I want an endpoint that returns simple array of items of type Log. I am aware that when initializing that, I should use many=True. But to also nicely generate the docs, I want to somehow represent that in get_serializer_class:

class ProcessingJobViewSet(GenericViewSet):
    queryset = ProcessingJob.objects.all()
    serializer_class = ProcessingJobSerializer

    def get_serializer_class(self):
        if self.action == "logs":
            return LogSerializer
        return self.serializer_class

    @action(detail=True, url_path="logs")
    def logs(self, request: Request, pk: int) -> Response:
        job = self.get_object()
        logs = retrieve_logs(job)
        return Response(LogSerializer(logs, many=True).data)

But how should I do it given that it needs to return the class def, not its instance? If I try to return ListSerializer(child=LogSerializer) it complains about child not being initialized and when I do initialize it, then it complains about ListSerializer object not callable.

The only workaround I found is to do:

class LogsSerializer(serializers.Serializer):
  results = LogSerializer(many=True)

but then I have a useless results key in the response.
