如何在drf中创建带验证的嵌套对象？

from rest_framework import serializers

class NestedObjectSerializer(serializers.Serializer):
    name = serializers.CharField(max_length=100, required=True)
    age = serializers.IntegerField(min_value=0, max_value=150, required=True)

class MainObjectSerializer(serializers.Serializer):
    id = serializers.IntegerField(read_only=True)
    nested_object = NestedObjectSerializer()

    def create(self, validated_data):
        nested_data = validated_data.pop('nested_object')
        main_object = MainObject.objects.create(**validated_data)
        NestedObject.objects.create(main_object=main_object, **nested_data)
        return main_object

from rest_framework.decorators import api_view
from rest_framework.response import Response

@api_view(['POST'])
def create_main_object(request):
    serializer = MainObjectSerializer(data=request.data)
    if serializer.is_valid():
        serializer.save()
        return Response(serializer.data, status=201)
    return Response(serializer.errors, status=400)
