Question

我正在尝试创建一个新的Category，只需要填充name字段，但它仍然会显示错误，说明它是必需的。

models.py ：

class Category(models.Model):
    name = models.CharField(max_length=32, unique=True)
    created_at = models.DateTimeField(default=timezone.now)
    updated_at = models.DateTimeField(default=timezone.now)

    def __str__(self):
        return self.name

serializers.py

class CategorySerializer(serializers.Serializer):
    id = serializers.IntegerField(required=False)
    name = serializers.CharField(max_length=32)

    def create(self, validated_data):
        return Category.objects.create(**validated_data)

    def update(self, instance, validated_data):
        pass

views.py

class CategoryList(APIView):
    def get(self, request):
        """
        Gets all the existing categories
        :param request:
        :return: Category
        """
        categories = Category.objects.all().filter().order_by("name")
        serializer = CategorySerializer(categories, many=True)

        return Response(serializer.data)

    def post(self, request):
        """
        Create one new category
        :param request:
        :return: Category
        """
        serializer = CategorySerializer(data=request.data)

        if serializer.is_valid():
            serializer.save()

            return Response(serializer.data, status=HTTP_201_CREATED)

        return Response(serializer.errors, status=HTTP_400_BAD_REQUEST)

引用request.data向我显示，例如：{'data': {'name': 'Withdrawal'}}。它显示正在发送和接收的数据，但我不明白为什么会出现这些错误。

我发现感谢丹尼尔罗斯曼。碰巧我正在使用React和Redux，我的行动如下：

export function createCategory({ data }) {
  return {
    [CALL_API]: {
      endpoint: '/api/categories/',
      method: 'POST',
      headers: {
        'Content-Type': 'application/json'
      },
      body: JSON.stringify({data}),
      types: [CREATE_CATEGORY, CREATE_CATEGORY_SUCCESS, CREATE_CATEGORY_FAILURE],
    },
  }
}

解决方案是删除body属性中的花括号。
