DRF:如何创建一个模型属性来统计喜欢和不喜欢的数量？

from django.db import models

class YourModel(models.Model):
    likes = models.IntegerField(default=0)
    dislikes = models.IntegerField(default=0)
    # 其他字段...

class YourModel(models.Model):
    # 其他字段...

    def add_like(self):
        self.likes += 1
        self.save()

    def add_dislike(self):
        self.dislikes += 1
        self.save()

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

class YourView(APIView):
    def post(self, request, pk):
        your_model = YourModel.objects.get(pk=pk)
        action = request.data.get('action')

        if action == 'like':
            your_model.add_like()
        elif action == 'dislike':
            your_model.add_dislike()

        return Response({'message': '操作成功'})
