Question

我一直在尝试用django编写一个应用程序 - 但它根本不起作用。我已经工作了一段时间 - 它正在完美地开发dev-server。但我无法投入生产环境（apahce）。

我的项目名称是apstat，应用名称是基本的。

我尝试按以下方式访问

块引用 http://hostname/apstat

但它显示以下错误：

MOD_PYTHON ERROR

    __import__(name)
ImportError: No module named basic

我的settings.py如下：

INSTALLED_APPS = (
    'django.contrib.auth',
    'django.contrib.contenttypes',
    'django.contrib.sessions',
    'django.contrib.sites',
    'apstat.basic',
    'django.contrib.admin',
)

如果我删除apstat.basic，它会通过，但这不是解决方案。这是我在apache中做的事情吗？

我的apache - 设置是 -

<VirtualHost *:80>
        ServerAdmin webmaster@localhost

        DocumentRoot /home/ubuntu/server/
        <Directory />
                Options None
                AllowOverride None
        </Directory>

        <Directory /home/ubuntu/server/apstat>
                AllowOverride None
                Order allow,deny
                allow from all
        </Directory>

        <Location "/apstat">
                SetHandler python-program
                PythonHandler django.core.handlers.modpython
                SetEnv DJANGO_SETTINGS_MODULE apstat.settings
                PythonOption django.root /home/ubuntu/server/
                PythonDebug On
                PythonPath "['/home/ubuntu/server/'] + sys.path"
        </Location>

</VirtualHost>

我现在已经坐了一天多了。如果有人可以帮助我，那将是非常好的。

Answer 1

您的基本版有__init__.py吗？

Answer 2

您需要确保项目位于PYTHONPATH。也许尝试在设置文件的顶部输出sys.path变量：

import sys
print sys.path

如果这不适用于mod_python，请尝试将其写入文件：

import sys
file('/tmp/mysyspath.txt', 'w').write(repr(sys.path))

但即使这样可行，也只是一个简短的警告： django社区不鼓励使用mod_python。它不再由其创建者维护，也不是部署django项目的最佳解决方案。如果您的服务器上有mod_wsgi，请尝试{{1}}。

Answer 3

通常项目目录已添加到sys.path，然后应用名称直接用于INSTALLED_APPS和其他应用中的导入。试一试。

Django - 没有名为app的模块
