Django 入門

安裝好後進入文件夾會看到裏面Django爲咱們建立好的文件裏

 

manage.py 爲咱們啓動服務的文件  python manage.py runserver 8080(啓動服務的時候默認是8000,後面加8080 能夠給他設置啓動服務的端口號)

db.sqlite3 這個文件是爲咱們提取建立好的鏈接數據庫的文件夾

 

進入mysite內

 

 __init__.py 爲初始化文件

settings.py 是配置文件

urls.py 是設置路由文件

wsgi.pt 

 

咱們進入settings.py看一下相關配置（我在下圖已經把相關配置對應的做用標準上備註）
