DjangMessages如何在syncdb期间创建通知类型？

Question

我将同时使用django-notification和django-messages项目，并利用django消息中内置的django通知集成，以及接收、回复消息时的默认通知类型

但是，我无法确定这些默认NoticeType对象是如何创建的。django通知文档建议在管理.py文件，这是我为自己的自定义通知所做的。我在任何代码中都找不到定义这些通知类型的任何地方。但每次我在新数据库上运行syncdb时，它们都会神奇地出现。在

由django messages应用程序创建的通知类型的“label”属性如下：

• 收到的消息
• 已发送消息
• 留言已回复
• 收到的消息
• 邮件已删除
• 消息已恢复

django_消息/管理.py公司名称：

from django.db.models import get_models, signals
from django.conf import settings
from django.utils.translation import ugettext_noop as _

if "notification" in settings.INSTALLED_APPS:
    from notification import models as notification

    def create_notice_types(app, created_models, verbosity, **kwargs):
        notification.create_notice_type("messages_received", _("Message Received"), _("you have received a message"), default=2)
        notification.create_notice_type("messages_sent", _("Message Sent"), _("you have sent a message"), default=1)
        notification.create_notice_type("messages_replied", _("Message Replied"), _("you have replied to a message"), default=1)
        notification.create_notice_type("messages_reply_received", _("Reply Received"), _("you have received a reply to a message"), default=2)
        notification.create_notice_type("messages_deleted", _("Message Deleted"), _("you have deleted a message"), default=1)
        notification.create_notice_type("messages_recovered", _("Message Recovered"), _("you have undeleted a message"), default=1)

    signals.post_syncdb.connect(create_notice_types, sender=notification)
else:
    print "Skipping creation of NoticeTypes as notification app not found"

类型在这里定义，并连接到后同步DB信号。在
