如何编写DRF序列化程序来处理封装我模型中定义的数据字段的JSON包装器？

from rest_framework import serializers

class MyModelSerializer(serializers.Serializer):
    field1 = serializers.CharField()
    field2 = serializers.IntegerField()
    # 添加其他字段...

class MyModelSerializer(serializers.Serializer):
    # 字段定义...

    def create(self, validated_data):
        # 处理数据的创建逻辑
        pass

    def update(self, instance, validated_data):
        # 处理数据的更新逻辑
        pass

class MyModelView(APIView):
    def get(self, request):
        # 查询模型数据
        queryset = MyModel.objects.all()
        # 创建序列化程序实例
        serializer = MyModelSerializer(queryset, many=True)
        # 序列化数据
        serialized_data = serializer.data
        # 返回序列化后的数据

    def post(self, request):
        # 反序列化数据
        serializer = MyModelSerializer(data=request.data)
        if serializer.is_valid():
            # 处理有效的反序列化数据
            serializer.save()
            # 返回成功的响应
        else:
            # 返回无效数据的错误响应
            pass
