Python Django管理员导致AttributeError

我正在用Django书学习Django。我正在使用Mavericks 10.9在Macbook Pro上运行python3.3.3，当我启用管理站点时，我收到Django服务器发出的“AttributeError:'RegexURLResolver'对象没有属性”\urlconf\u module'”错误。我已经检查（并发布）了我的settings.py和url.py文件，没有发现任何问题

我在GIT上发现了一个类似的条目，但我不相信它适用于我身上发生的事情。我认为这可能是Mavericks的问题，所以我运行了所有brew更新和django的pip升级，但我仍然收到这个错误

有什么想法吗

解决方案，在我看来很奇怪，是我在views.py文件中指定了根文件夹作为books.models导入的开始。这似乎不仅破坏了管理启动，而且它给出的错误没有给出太多（如果有的话）根本问题的指示。只有当我回到Python2.7时，错误消息才给了我一些问题根源的指示。

---

我猜这是典型的新手风格，因为现在很明显，站点的“根”应该是包含manage.py的文件夹，因此不应该在任何路径规范中。尽管这本书似乎没有说明…

我在尝试运行驻留在django项目之外的测试模块时遇到了这个错误（django实践似乎不支持）：

这个错误是由django在进程的不同点假设了不同的导入路径引起的，所以我通过附加到

sys.path

解决了这个问题。在生产环境中这样做我会犹豫不决，但我可以接受测试中的一些黑客行为

下面是我在

test\u example\u app.py中得到的结果：

import os
import sys

import django
from django.conf import settings
from django.test import LiveServerTestCase
from django.test.utils import get_runner

class TestExampleApp(LiveServerTestCase):
   ...

if __name__ == '__main__':
    sys.path.append(os.path.realpath('./example_project'))
    os.environ['DJANGO_SETTINGS_MODULE'] = 'example_project.project.settings'
    django.setup()

    sys.path.append(os.path.realpath('./example_project/project'))
    testrunner = get_runner(settings)()
    failures = testrunner.run_tests(['test_example_app'])
    sys.exit(bool(failures))

我知道这是wierd，但是你能在设置中交换
CommonMiddleware
和
SessionMiddleware
，然后再试一次吗？你运行的是什么版本的django？谢谢Karthikr，但没有任何区别。我想可能是python 3的问题？我切换到了python 2.7.6，现在我得到了一些其他东西。（importorror at/admin/No module named books.models）我开始认为将我的models文件夹放在顶层文件夹中是不正确的。它应该在哪里？是否使用settings.py？
import os
import sys

import django
from django.conf import settings
from django.test import LiveServerTestCase
from django.test.utils import get_runner

class TestExampleApp(LiveServerTestCase):
   ...

if __name__ == '__main__':
    sys.path.append(os.path.realpath('./example_project'))
    os.environ['DJANGO_SETTINGS_MODULE'] = 'example_project.project.settings'
    django.setup()

    sys.path.append(os.path.realpath('./example_project/project'))
    testrunner = get_runner(settings)()
    failures = testrunner.run_tests(['test_example_app'])
