python - 在 app-engine-patch 中导入 django 设置

Question

我对 Django 设置有疑问。我的应用程序使用应用程序引擎补丁运行。我添加了一个无需 django 即可运行的脚本，可通过 app.yaml 处理程序直接访问。然后我得到这个错误:

File "/base/python_runtime/python_lib/versions/third_party/django-0.96/django/conf/__init__.py", line 53, in _import_settings
raise EnvironmentError, "Environment variable %s is undefined." % ENVIRONMENT_VARIABLE
<type 'exceptions.EnvironmentError'>: Environment variable DJANGO_SETTINGS_MODULE is undefined.

我在谷歌上找到了这个提示:

# Force Django to reload its settings.
from django.conf import settings
settings._target = None

# Must set this env var before importing any part of Django
os.environ['DJANGO_SETTINGS_MODULE'] = 'settings' 

但后来我得到了这个错误:

raise EnvironmentError, "Could not import settings '%s' (Is it on sys.path? Does it have syntax errors?): %s" % (self.SETTINGS_MODULE, e)
<type 'exceptions.EnvironmentError'>: Could not import settings 'settings.py' (Is it on sys.path? Does it have syntax errors?): No module named ragendja.settings_pre

我认为是app-engine-patch路径修改的问题，如何正确导入settings_pre？

谢谢!

改变

os.environ['DJANGO_SETTINGS_MODULE'] = 'settings.py' 

到

os.environ['DJANGO_SETTINGS_MODULE'] = 'settings'

DJANGO_SETTINGS_MODULE 的值是模块的名称(即，就像您在 Python 脚本中的 import 语句中编写的那样)，而不是模块的路径模块。
