要使用setattr:

for key in changes.keys():
  setattr(user, key, changes.get(key))

user.save()

尝试更新你的 str 释义这用作下拉显示值,您当前正在设置类名。如果要在下拉列表中显示标题:

class activity(models.Model):
    title = models.CharField(max_length=30,default=None)
    date_created = models.DateTimeField(auto_now_add=True)
    date_updated = models.DateTimeField(auto_now=True)
    author = models.ForeignKey(User,on_delete=models.CASCADE,default=None)

    def __str__(self):
        return self.title
