python - django rest framework 在列表显示中隐藏特定字段？

Question

I want to hide specific fields of a model on the list display at persons/ and show all the fields on the detail display persons/jane

我对 rest 框架比较陌生，文档感觉很难掌握。

这是我想要完成的。

我有一个简单的 Person模型，

# model
class Person(models.Model):
    first_name = models.CharField(max_length=30, blank=True)
    last_name = models.CharField(max_length=30, blank=True)
    nickname = models.CharField(max_length=20)
    slug = models.SlugField()
    address = models.TextField(max_length=300, blank=True)

和序列化器类

# serializers

class PersonListSerializer(serializers.ModelSerializer):
    class Meta:
        model = Person
        fields = ('nickname', 'slug')


class PersonSerializer(serializers.ModelSerializer):
    class Meta:
        model = Person
        fields = ('first_name', 'last_name', 'nickname', 'slug', 'address')

和 View 集。

# view sets (api.py)

class PersonListViewSet(viewsets.ModelViewSet):
    queryset = Person.objects.all()
    serializer_class = PersonListSerializer


class PersonViewSet(viewsets.ModelViewSet):
    queryset = Person.objects.all()
    serializer_class = PersonSerializer

在 url persons 我想显示人员列表，只显示字段 nickname和 slug在网址 persons/[slug] 我想显示模型的所有字段。

我的路由器配置，

router = routers.DefaultRouter()
router.register(r'persons', api.PersonListViewSet)
router.register(r'persons/{slug}', api.PersonViewSet)

我猜第二个配置是错误的，我怎样才能实现我想要做的？

更新:

输出到 persons/slug 是 {"detail":"Not found."}但它适用于 person/pk

谢谢

对于遇到此问题的任何其他人，我发现在 View 集上重写 get_serializer_class 并为每个操作定义一个序列化程序是 DRY-est 选项(保留单个 View 集但允许动态序列化程序选择):

class MyViewset(viewsets.ModelViewSet):
    serializer_class = serializers.ListSerializer
    permission_classes = [permissions.IsAdminUser]
    renderer_classes = (renderers.AdminRenderer,)
    queryset = models.MyModel.objects.all().order_by('-updated')

    def __init__(self, *args, **kwargs):
        super(MyViewset, self).__init__(*args, **kwargs)
        self.serializer_action_classes = {
            'list':serializers.AdminListSerializer,
            'create':serializers.AdminCreateSerializer,
            'retrieve':serializers.AdminRetrieveSerializer,
            'update':serializers.AdminUpdateSerializer,
            'partial_update':serializers.AdminUpdateSerializer,
            'destroy':serializers.AdminRetrieveSerializer,
        }

    def get_serializer_class(self, *args, **kwargs):
        """Instantiate the list of serializers per action from class attribute (must be defined)."""
        kwargs['partial'] = True
        try:
            return self.serializer_action_classes[self.action]
        except (KeyError, AttributeError):
            return super(MyViewset, self).get_serializer_class()

希望这对其他人有帮助。
