Python 在谷歌应用程序引擎上使用Django的困难

我有一个Django 1.1.1项目，它运行良好。我正在尝试将其导入谷歌应用程序引擎

我试着跟着这些

我在dev服务器上运行它，得到一个导入错误：

ImportError at /
No module named mysite.urls

这是mysite/的文件夹结构：

app.yaml
<DIR>          myapp
index.yaml

manage.py
<DIR>          media

# Unregister the rollback event handler.
django.dispatch.dispatcher.disconnect(
    django.db._rollback_on_exception,
    django.core.signals.got_request_exception)

def main():
    # Create a Django application for WSGI.
    application = django.core.handlers.wsgi.WSGIHandler()

    # Run the WSGI CGI handler with that application.
    util.run_wsgi_app(application)

manage.py
<DIR>          media
settings.py

    django.db._rollback_on_exception,
    django.core.signals.got_request_exception)

def main():
    # Create a Django application for WSGI.
    application = django.core.handlers.wsgi.WSGIHandler()

    # Run the WSGI CGI handler with that application.
    util.run_wsgi_app(application)

<DIR> mysite

<DIR> myapp
<DIR> media

我做错了什么

我觉得我离这里越来越近了，但仍然不在那里。

我还没有将纯django与appengine一起使用。但据我所知，你需要Djangappengine补丁来让它工作。您可以阅读并从下载。

尝试将

ROOT\u URLCONF

更改为

'url'

。我认为在appengine上运行时，应用程序的父目录（在appengine意义上，而不是Django意义上）不在

sys.path

上，这意味着它不会将

mysite

视为Python包/模块

编辑以跟上编辑的问题：

application: mysite
version: 1
runtime: python
api_version: 1

handlers:
- url: .*
  script: main.py

现在听起来您无意中使用了Django 0.96，但希望使用Django 1.1+。当您在App Engine上导入django时，除非您明确告诉App Engine您要使用不同的版本，否则最终将得到0.96

差不多

from google.appengine.dist import use_library
use_library('django', '1.1')

我们应该做这个把戏。请注意，为了在开发服务器上使用它，您必须安装自己的Django 1.1副本，因为它没有与SDK捆绑在一起

---

还请注意，据我所知，您使用AppEngine上的Django admin站点不会有任何运气。

以下是我的main.py：

import os
import sys
import logging

# Google App Hosting imports.
from google.appengine.ext.webapp import util
from google.appengine.dist import use_library

os.environ["DJANGO_SETTINGS_MODULE"] = "mysite.settings"
sys.path.append("/home/brox/tmp/mysite")

use_library('django', '1.1')

# Enable info logging by the app (this is separate from appserver's
# logging).
logging.getLogger().setLevel(logging.DEBUG)

def log_exception(*args, **kwds):
  logging.exception('Exception in request:')

# Force sys.path to have our own directory first, so we can import from it.
sys.path.insert(0, os.path.abspath(os.path.dirname(__file__)))

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

import django.core.handlers.wsgi

import django.db

# Log errors.
django.dispatch.Signal.connect(
   django.core.signals.got_request_exception, log_exception)

# Unregister the rollback event handler.
django.dispatch.Signal.disconnect(
django.core.signals.got_request_exception,
django.db._rollback_on_exception)

def main():    
    # Create a Django application for WSGI.

    # Run the WSGI CGI handler with that application.
    util.run_wsgi_app(application)

if __name__ == "__main__":
    main()

正如您所看到的，还有其他路径，django错误日志记录有点不同

希望能对您有所帮助。

这样做很有效，但我还有更多问题。（OP更新。）现在查看我编辑的答案。虽然你可能应该结束这个问题，打开一个新的问题，因为你现在有一个不同的问题。这有点奏效，但我仍然有更多的问题。（OP更新。）现在查看我编辑的答案。虽然你可能应该关闭这个问题，打开一个新的，因为你现在有一个不同的问题。
