Question

我最近将一个应用程序添加到了Django Web应用程序中。我对正在发生的问题感到困惑。当我将下面的admin.py文件添加到应用程序并部署代码时，响应时间在站点的多个区域中增加，而许多区域无关。 ModelAdmin的编写方式有问题吗？有人经历过吗？我正在运行Django 1.11。

admin.py：

class SubscriberAdmin(admin.ModelAdmin):
    list_display = ('email',)
    fields = ('email', 'verified')
    readonly_fields = ('email', 'verified')
    list_per_page = 50


admin.site.register(Subscriber, SubscriberAdmin)

models.py：

class Subscriber(models.Model):
    email = models.EmailField(null=False, unique=True)
    activation_key = models.CharField(max_length=64)
    key_expires = models.DateTimeField(default=get_key_expiration)
    verified = models.BooleanField(default=False)

    agency_class = {}
    agency_type = None

    @classmethod
    def send_notifications(cls, agency_type, slugs):
        """
        Sends notification emails to all subscribers.
        :param agency_type: 'salary' or 'pension'
        :param slugs: [list of agency slugs]
        """
        cls._set_agency_type(agency_type)

        subscribers = cls.objects.all()
        for subscriber in subscribers:
            subscriber._send_notification(slugs)

    def _send_notification(self, slugs):
         # code removed for brevity

问题可能出在get_key_expiration。也许每次创建对象订户并且函数运行缓慢时都会调用该函数吗？
