def retrieve(self, request, *args, **kwargs):
        chairman = Chairman(id=kwargs['id'])
        serializer = self.get_serializer(chairman)
        return Response(serializer.data)

# class ChairmanList(generics.ListAPIView):
#     queryset = Chairman.objects.all().order('-num')
#     serializer_class = ChairmanSerializer
#
#
# class ChairmanDetail(mixins.RetrieveModelMixin,
#                      generics.GenericAPIView):
#     queryset = Chairman.objects.all()
#     serializer_class = ChairmanSerializer
#     lookup_field = ('id')
#
#     def get(self, request, *args, **kwargs):
#         chairman = Chairman(id=kwargs['id'])
#         serializer = self.get_serializer(chairman)
#         return Response(serializer.data)
