所以想請問有經驗的人是用哪一套在local端開發的呢?

local端web server應該用django附的dev server就夠了(./manage.py runserver)
DBMS的部分如果沒有用到特殊field(JSONField那類)的話應該就用SQLite就足夠了

資料如何管控，例如local 端是去存取另外一個資料庫嗎? 如果是另一個資料庫，那deploymenet的時候又要改來改去了。

1. 你可以分成devlopment用的和production用的settings.py https://gist.github.com/andy23512/6a5c6488c2576be1bf1b659a45c380e5 這個是我為了跑自動化測試而另外寫出的test_settings.py 這樣只要在執行時附加--settings=web.test_settings就可以使用不同的settings
