我的環(huán)境是windows7 + python34 + django1.8

?

下面兩篇文章提到了django的scaffold，感覺是一個挺不錯的功能：

Django實戰(zhàn)（3）：Django也可以有scaffold

Django1.5+Python3.3下groundwork的使用

?

于是去Github下載了django-groundwork（居然是四年以前更新過-_-!!!），解壓后復制整個django-groundwork文件夾到當前項目文件夾下。

再設(shè)置settings.py：

INSTALLED_APPS = (# ...'django-groundwork', )

然后運行:

$ python manage.py groundwork depot Product

?出現(xiàn)了如下錯誤：

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官方文檔，發(fā)現(xiàn)django1.8的manage.py的命令行參數(shù)解析模塊已經(jīng)由optparse換成了argparse

所以，四年前寫的groundwork自然是不能運行了。好吧，自己動手，豐衣足食。

我把里面的兩個文件做了必要的修改：

?

保存，然后運行：

$ python manage.py groundwork depot Product

?

?不用再做任何修改，操作。啟動服務(wù)器：

$ python manage.py runserver

?在瀏覽器地址欄輸入：

localhost:8000/depot/product/list

?

您會看到如下效果圖：

?點擊 Add New，進入create頁面

?最后為了方便大家使用，我Fork了原來的django-groundwork到我的Github，并做了相應(yīng)的修改。祝使用愉快！
