python - Django + GoogleAppEngine 错误 : DJANGO_SETTINGS_MODULE is undefined

Question

因此，我正在学习如何使用 Django，并且正在使用 Google App Engine。我在与主目录相同的目录中有最新的 Django 目录。

当我从本地运行它时，它工作正常。但是，当我部署它并从网页运行它时，出现服务器错误。

这是我的 main.py 和 settings.py 的代码

主要.py:

import os
import settings
from django.template import Context, Template
from google.appengine.ext import webapp
from google.appengine.ext.webapp.util import run_wsgi_app

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

class MainPage(webapp.RequestHandler):
    def get(self):
        self.response.headers['Content-Type'] = 'text/plain'
        self.response.out.write('Hello, World!\n')
        t = Template('It is now {% now "jS F Y H:i" %}')
        c = Context({ })
        self.response.out.write(t.render(c))

application = webapp.WSGIApplication(
                                     [('/', MainPage)],
                                     debug=True)

def main():
    run_wsgi_app(application)

if __name__ == "__main__":
    main()

设置.py:

import os

DEBUG = True
TEMPLATE_DEBUG = DEBUG
TIME_ZONE = 'America/Whitehorse'
LANGUAGE_CODE = 'en-us'
SITE_ID = 1

如果您在使用环境变量时遇到问题，请尝试直接配置设置(请参阅 http://docs.djangoproject.com/en/dev/topics/settings/#using-settings-without-setting-django-settings-module)

import settings
import django.conf

# Filter out all the non-setting attributes of the settings module
settingsKeys = filter(lambda name: str(name) == str(name).upper(), 
                      dir(settings))

# copy all the setting values from the settings module into a dictionary
settingsDict = dict(map(lambda name: (name, getattr(settings, name)), 
                        settingsKeys))

django.conf.settings.configure(**settingsDict)
