Django Rest Framework序列化程序:验证object.user是否为request.user

from rest_framework import serializers

class MySerializer(serializers.ModelSerializer):
    def validate(self, data):
        object_user = data.get('user')
        request_user = self.context['request'].user

        if object_user != request_user:
            raise serializers.ValidationError("object.user must be the same as request.user")

        return data

    class Meta:
        model = MyModel
        fields = '__all__'

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

class MyView(APIView):
    def post(self, request):
        serializer = MySerializer(data=request.data, context={'request': request})
        if serializer.is_valid():
            # 执行其他操作
            return Response(serializer.data)
        else:
            return Response(serializer.errors, status=400)
