django/rest:我可以有一个只有一个字段的序列化程序吗?

我正在使用 django 1.11.5 和python 3.5。

使用 rest-framework ,我想搜索一位患有 uid .

The 领域 option must be a list or tuple or "__all__". Got str. .

只有一个字段来搜索用户,有什么解决方案吗?

class GetUserSerializer(serializers.ModelSerializer):
    id = serializers.CharField(source='uid')

    class Meta:
        model = User
        fields = ('id')

意见。py公司

class GetUser(CreateAPIView):
    permission_classes = ()
    serializer_class = GetUserSerializer

    def get(self, request):
        serializer = GetUserSerializer(data=request.data)
        # Check format and unique constraint
        if not serializer.is_valid():
            return Response(serializer.errors, \
                            status=status.HTTP_400_BAD_REQUEST)
        data = serializer.data


        if User.objects.filter(uid = data['id']).exists():
            user = User.objects.get(uid = data['id'])
            resp = {"user":{"uid":user.uid, "firstname":user.firstname, "yearofbirth": user.yearofbirth, \
                            "lastnames": user.lastname, "othernames": user.othernames}}
            return Response(resp, status=status.HTTP_200_OK)

        else:

            resp = {"error": "User not found"}
            return Response(resp, status=status.HTTP_404_NOT_FOUND)

模型。py公司

class User(models.Model):
    uid = models.CharField(max_length=255, unique=True,default="0")
    firstname = models.CharField(max_length=255)
    lastname = models.CharField(max_length=255, blank=True)
    othernames = models.CharField(max_length=255, blank=True)
    yearofbirth = models.SmallIntegerField(validators=[MinValueValidator(1900),
                                           MaxValueValidator(2018)], null = False
