无法将Django设置导入Google App Engine

Question

大家好，Google App Engine的专家们，

我之前用过一点Django，但对Google App Engine还是新手，这次是第一次尝试用它的开发网页服务器和Django一起工作。

我不知道这是否重要，但我之前在Windows XP上安装过Django 1.1和Python 2.6，虽然我已经卸载了Python 2.6，但系统里仍然有一个文件夹和一些注册表的记录。

我按照Google的说明进行了操作，但当我访问GAE开发网页服务器时，它找不到我的设置（具体情况见下文）。

如果有任何提示，我将非常感激。

祝好

Geoff

Answer 1

你是怎么用Django和谷歌应用引擎开发这个应用的呢？

如果你在用Django的话，settings.py这个文件应该已经存在了。

可以试试 App engine patch

这个工具可以帮助你更好地开始用谷歌应用和Django开发应用。

Answer 2

为了在本地测试，先在你的main.py文件开头加上这些内容。

import os, sys
os.environ["DJANGO_SETTINGS_MODULE"] = "appid.settings"
sys.path.append("/app/folder")

Answer 3

我遇到过类似的问题，我在我的根目录下放了一个空的settings.py文件，然后就解决了。

祝你好运！
