我试图在同一个项目上部署django notification和django avatar，但是，当我运行python2 manage.py syncdb时，我收到以下异常：

奇怪！呵呵？我甚至不知道为什么会发生这种错误。有什么帮助吗？

这是因为django notification的最新版本（位于1.0版）已被重构并从models.py中删除了create\u notice\u type

这很麻烦，因为当前版本的django avatar和django postman依赖于create_notice_type

为了解决这个问题，我必须通过以下方式安装django通知的早期版本：

pip install django-notification==0.2

对，创建通知类型已被删除。 只需创建NoticeType的一个实例，如下所示：

# static block:
try:
    notification = get_app( 'notification' )
except ImproperlyConfigured:
    notification = None
..

# in your method:
if notification is not None and "notification" in settings.INSTALLED_APPS:
from django.utils.translation import ugettext_noop as _

message = {

    'user':     settings.DEFAULT_FROM_EMAIL, 
    'comment':  'no comment', 
    'type':     'welcome', 
    'descr':    'my description',
    # ..
}
try:

    notification.send([to_user], "welcome", message)
except NoticeType.DoesNotExist:
    NoticeType.create("welcome", _("Bla Bla"), _("How nice of you to visit our site"))
    notification.send([to_user], "welcome", message)
