Question

我正在使用Django Book学习Django。我在Macbook Pro上使用Mavericks 10.9运行python3.3.3，当我启用管理站点时，我得到了＃34;发生了服务器错误。请联系管理员。＆＃34;在浏览器中＆＃34; 属性错误：＆＃39; RegexURLResolver＆＃39;对象没有属性＆＃39; _urlconf_module＆＃39; ＆＃34; Django服务器出错。我已经检查（并发布了）我的settings.py和urls.py文件，并且没有看到任何问题......

我在GIT here上找到了类似的项目，但我不相信它适用于我所发生的事情。我认为这可能是一个小牛队的问题，所以我运行了所有brew更新和django的pip升级，但我仍然收到此错误...

任何想法？

Answer 1

我在尝试运行位于我的django项目之外的测试模块时遇到此错误（练习django似乎不支持）：

$ tree
.
├── example_project
│   ├── example_app
│   │   ├── __init__.py
│   │   └── models.py
│   ├── __init__.py
│   ├── manage.py
│   └── project
│       ├── __init__.py
│       ├── settings.py
│       ├── urls.py
│       └── wsgi.py
└── test
    └── test_example_app.py

错误是由django在进程中的不同点假设不同的导入路径引起的，所以我通过附加到sys.path来解决它。我在生产环境中犹豫不决，但我可以在测试中接受一些黑客行为。

以下是test_example_app.py中的最终结果：

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))

解决方案，就像在我看来一样奇怪，我已经将根文件夹指定为views.py文件中books.models导入的开始。这似乎不只是炸毁管理员的开始，但它给出的错误没有给出根本问题的很多（如果有的话）。只有当我回滚到python 2.7时，错误消息才能给我一些问题根源的指示。我猜这是经典的新手，因为现在很明显网站的“根”应该是其中包含manage.py的文件夹，因此不应该在任何路径规范中。虽然这本书似乎没有说明......
