在Django Rest中的一些布尔值后使视图禁用

Question

models.py

class One(models.Model):
    user = models.ForeignKey(User, on_delete=models.CASCADE)
    one = models.CharField(max_length=20)
    ses = models.IntegerField()
    occupied = models.BooleanField(default=False)

我有occupied个布尔字段，默认为False。我想禁用各自的视图或仅在占据True

之后才读取

serializers.py

class OneSerializer(serializers.ModelSerializer):
    class Meta:
        model = One
        field = '__all__'
        read_only_fields = ('user',)

views.py

class OneView(APIView):
    @staticmethod
    def get(request):
        user = request.user
        apt = One.objects.filter(user=user)
        if type(apt)==Response:
            return apt
        return Response(OneSerializer(apt).data)

    @staticmethod
    def post(request):
        serializer  = OneSerializer(data=request.data, context = {'request':request})
        if serializer.is_valid():
            user = request.user
            serializer.save(user=user)
            return Response(OneSerializer(serializer.instance).data, status=201)
        return Response(serializer.errors, statusl=400)

我该如何使该功能设置为True，使各自的视图仅对所有者用户只读？

Answer 1

尝试如下更改您的get()方法

class OneView(APIView):
    @staticmethod
    def get(self, request, **kwargs):
        user = request.user
        apt = One.objects.get(user=user)
        if apt.occupied:
            return Response(OneSerializer(apt).data)
        return Response()

如果您返回诸如类之类的HttpResponse以外的任何内容，则DRF将引发 AssertionError 作为

  / some / end / point /处的

AssertionError预期响应，HttpResponse   或从视图返回HttpStreamingResponse，但收到一个   

此外，我认为您的方法中不需要@staticmethod。 DRF-Doc教会了我们在没有staticmethod装饰器的情况下做到这一点。
