在Python web 框架中氓辣，Django 算是比較重的一個(gè)。
不同的版本埂息，寫法還很不一樣皮璧。高版本對(duì)低版本也不兼容舟扎。
2010年用django 1.3 寫的一個(gè)有圖片上傳下載的小博客，后來運(yùn)行不了了悴务。關(guān)鍵是我自己還調(diào)不通了:(
后來也斷斷續(xù)續(xù)寫過幾個(gè)Django的項(xiàng)目睹限。在生產(chǎn)環(huán)境下，對(duì)原生的django改造比較多讯檐。最近在基于Django搭一個(gè)web backend 框架羡疗。想到一步步整理一下，包括django原生的通過django-admin創(chuàng)建project, 創(chuàng)建app都整理記錄一下..
下面是通過django-admin創(chuàng)建一個(gè)最原始的django web.
$ django-admin startproject project_001
$ cd project_001
$ python manage.py runserver
