在DRF中管理自定义序列化程序的最佳方式是什么

from rest_framework import serializers
from .models import YourModel

class YourSerializer(serializers.Serializer):
    field1 = serializers.CharField()
    field2 = serializers.IntegerField()

    def create(self, validated_data):
        # 处理创建对象的逻辑
        return YourModel.objects.create(**validated_data)

    def update(self, instance, validated_data):
        # 处理更新对象的逻辑
        instance.field1 = validated_data.get('field1', instance.field1)
        instance.field2 = validated_data.get('field2', instance.field2)
        instance.save()
        return instance

from .custom_serializers import YourSerializer

class YourView(APIView):
    def post(self, request):
        serializer = YourSerializer(data=request.data)
        if serializer.is_valid():
            serializer.save()
            return Response(serializer.data, status=status.HTTP_201_CREATED)
        return Response(serializer.errors, status=status.HTTP_400_BAD_REQUEST)
