Question

我通过

创建了一个 askbot 项目

askbot-setup

和

python manage.py syncdb # answered 'no' when asked to create superuser account
python manage.py migrate

我从 shell 创建了一个超级用户：

from django.contrib.auth.models import User
User.objects.create_superuser('admin', admin@example.com', 'pass')

然后我运行dev服务器并通过浏览器访问localhost

python manage.py runserver

一切似乎都很好。但是当我从管理页面注销时，会发生异常：

AttributeError at /admin/logout/
'AnonymousUser' object has no attribute 'get_and_delete_messages'
Request Method: GET
Request URL:    http://localhost:8000/admin/logout/
Django Version: 1.5
Exception Type: AttributeError
Exception Value:    
'AnonymousUser' object has no attribute 'get_and_delete_messages'

Python Executable:  /usr/bin/python
Python Version: 2.7.4

回溯：

Traceback:

File "/usr/local/lib/python2.7/dist-packages/askbot/user_messages/context_processors.py" in user_messages
  21.     messages = request.user.get_and_delete_messages()

任何帮助？

我找到了解决方案。

我还在http://askbot.org/en/question/11782/admin-logout-throw-exception/发布了这个帖子，使用 hailong 作为用户名。

我通过修改/usr/local/lib/python2.7/dist-packages/askbot/user_messages/context_processors.py

解决了这个问题

# messages = request.user.get_and_delete_messages() .... original, prox. line 22
messages = get_and_delete_messages(request)

因为我发现函数get_and_delete_messages仅被定义为该文件中的“独立”函数，而不是某个类的方法。但它被用作request.user.get_and_delete_messages()。我认为这是一个错字。如果我是对的，另一个拼写错误是/usr/local/lib/python2.7/dist-packages/askbot/user_messages/__init__.py（相同用法）。

如果我错了，请纠正我。但这可能是我的解决方案有效。

从django admin注销时：“AnonymousUser”对象没有属性“get_and_delete_messages”
