Django Rest框架，如何创建或更新将嵌套序列化程序作为其字段之一的对象

from rest_framework import serializers

class NestedSerializer(serializers.Serializer):
    # 定义字段
    field1 = serializers.CharField()
    field2 = serializers.IntegerField()
    # 其他字段...

class MainSerializer(serializers.Serializer):
    # 定义字段，包括嵌套序列化程序字段
    field1 = serializers.CharField()
    field2 = serializers.IntegerField()
    nested_field = NestedSerializer()
    # 其他字段...

from rest_framework.views import APIView
from rest_framework.response import Response

class MyView(APIView):
    def post(self, request):
        serializer = MainSerializer(data=request.data)
        if serializer.is_valid():
            # 创建或更新对象
            instance = serializer.save()
            # 其他操作...
            return Response(serializer.data)
        return Response(serializer.errors)
