我的环境是windows7 + python34 + django1.8
下面两篇文章提到了django的scaffold，感觉是一个挺不错的功能：
Django实战（3）：Django也可以有scaffold
Django1.5+Python3.3下groundwork的使用
于是去Github下载了django-groundwork（居然是四年以前更新过-_-!!!），解压后复制整个django-groundwork文件夹到当前项目文件夹下。
再设置settings.py：
INSTALLED_APPS = (
# ...
'django-groundwork',
)
然后运行:
$ python manage.py groundwork depot Product
出现了如下错误：
E:\workspace\depot>python manage.py groundwork depotapp Product
usage: manage.py groundwork [-h] [--version] [-v {0,1,2,3}]
[--settings SETTINGS] [--pythonpath PYTHON
[--traceback] [--no-color]
manage.py groundwork: error: unrecognized arguments: depotapp Product
查看django官方文档，发现django1.8的manage.py的命令行参数解析模块已经由optparse换成了argparse
所以，四年前写的groundwork自然是不能运行了。好吧，自己动手，丰衣足食。
我把里面的两个文件做了必要的修改：

保存，然后运行：
$ python manage.py groundwork depot Product
不用再做任何修改，操作。启动服务器：
$ python manage.py runserver
在浏览器地址栏输入：
localhost:8000/depot/product/list
您会看到如下效果图：
点击 Add New，进入create页面
最后为了方便大家使用，我Fork了原来的django-groundwork到我的Github，并做了相应的修改。祝使用愉快！
