Question

有人可以帮助我将django应用程序转换为Google App Engine（GAE）吗？我想知道我的django应用程序中的所有文件并将它们复制到GAE应用程序。但是，我不确定如何配置GAE的默认文件。 main.py文件应该如何运行django应用程序，就像它设计的那样：

main.py

import webapp2

class MainHandler(webapp2.RequestHandler):
    def get(self):
        self.response.write('Hello world!')

app = webapp2.WSGIApplication([
    ('/', MainHandler)
], debug=True)

的app.yaml

application: appname
version: 1
runtime: python27
api_version: 1
threadsafe: true

libraries:
- name: django
  version: "1.3"

builtins:
- django_wsgi: on

我在app引擎上运行了一个django应用。我按照这个链接启动并运行。 http://www.allbuttonspressed.com/projects/djangoappengine。与常规django相比，所有配置文件都有很多变化。我现在不使用django因为我喜欢app引擎而且讨厌django。以下是我的一些文件示例。请注意，在你的问题中，你有一个webapp2请求处理程序，你不会使用django这样的东西。它将所有常规视图定义作为函数，而不是像app引擎这样的类。如果您决定尝试这种方法，请告诉我它是怎么回事。

在我按照上面的链接后，这就是我的app.yaml。

application: app
version: production
runtime: python27
api_version: 1
threadsafe: yes

libraries:
- name: django
  version: latest


handlers:
- url: /_ah/queue/deferred
  script: djangoappengine.deferred.handler.application
  login: admin

- url: /_ah/stats/.*
  script: djangoappengine.appstats.application

- url: /.*
  script: djangoappengine.main.application

我的settings.py

# Initialize App Engine and import the default settings (DB backend, etc.).
# If you want to use a different backend you have to remove all occurences
# of "djangoappengine" from this file.
from djangoappengine.settings_base import *

TEMPLATE_DIRS = (

    os.path.join(os.path.dirname(__file__), 'media'),

    )

def main():

    # Run the WSGI CGI handler with that application.
