在syncdb中，django-messages是如何創建通知類型的？

Question

我使用的django-notification和django-messages項目組合在一起，並採取內置於Django的消息，其違約通知類型收到短信時的Django的通知整合的優勢，回覆等

然而，我無法確定如何創建這些默認的NoticeType對象。 Django通知文檔建議在management.py文件中使用post_syncdb信號，這是我爲自己的自定義通知所做的。我無法在這些通知類型定義的任何代碼中找到任何地方。然而，每當我在新數據庫上運行syncdb時，它們都會奇蹟般地出現。

正在由Django的消息的應用程序所創建的通知類型的 「標記」 屬性如下：

• messages_received
• messages_sent
• messages_replied
• messages_reply_received
• messages_deleted
• messages_recovered

django_messages/management.py：

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"

類型在這裏定義和鉤在post_syncdb信號。
