我正在尝试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，我收到此异常：

奇怪！是吧？我甚至不确定为什么会发生这种错误。有什么帮助吗？

Answer 1

是的，create_notice_type已被删除。只需创建一个NoticeType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)

Answer 2

这是因为最新版本的django-notification（版本1.0位于here）被重构并从models.py中删除了create_notice_type ....

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

所以要解决这个问题，我必须通过以下方式安装先前版本的django通知：

pip install django-notification==0.2

django-notification：AttributeError：'module'对象没有属性'create_notice_type'
