Question

我有模型（对象），其中包含一些字段+ 评分：

class Object(PolymorphicModel):
    author = models.ForeignKey(ProfileUser, on_delete=models.CASCADE, db_column='author')
    title = models.CharField(max_length=300)
    city = models.ForeignKey(City, on_delete=models.CASCADE)
    address = models.CharField(max_length=300)
    phone = models.CharField(max_length=20, default='')
    email = models.CharField(max_length=100, default='')
    site = models.CharField(max_length=100, default='')
    facebook = models.CharField(max_length=100, default='')
    instagram = models.CharField(max_length=100, default='')
    content = models.TextField()
    rating = models.IntegerField(default=10)
    created_date = models.DateTimeField(default=timezone.now)
    approved_object = models.BooleanField(default=False)
    admin_seen = models.BooleanField(default=False)

    def __str__(self):
        return f"{self.title}"

这些对象还具有评论模型：

class Comment(models.Model):
    object = models.ForeignKey(Object, on_delete=models.CASCADE, related_name='comments')
    author = models.ForeignKey(ProfileUser, on_delete=models.CASCADE, db_column='author')
    content = models.TextField()
    rating = models.TextField()
    approved_object = models.BooleanField(default=False)
    admin_seen = models.BooleanField(default=False)
    created_date = models.DateTimeField(default=timezone.now)

    def __str__(self):
        return f"{self.content}"

好了，这是笔交易，我有approved_object和admin_seen，它们在Django Admin中的单选按钮中都表示出来。我想在某些管理员打开未批准的评论并检查admin_seen和approved_object单选按钮时，脚本应使用Comment.objects.filter(object_id=pk).aggregate(Avg('rating'))['rating__avg']更新评分和平均评分，所以我发现了用def save_method重写保存方法，但是我不知道如何处理是否选中单选按钮并更新等级？

admin.py ：

class CommentScreenAdmin(admin.ModelAdmin):
    raw_id_fields = ('author', 'object')

    def save_model(self, request, obj, form, change):
#to do...

有没有办法处理管理员单选按钮的更改？
