django 基礎學習

標籤：python   import   please   django   

一、建立django程式

• 終端命令：django-admin startproject sitename

• IDE建立Django程式時，本質上都是自動執行上述命令

二、程式目錄

三、設定檔

1、資料庫

DATABASES = {    ‘default‘: {        #‘ENGINE‘: ‘django.db.backends.sqlite3‘,        #‘NAME‘: os.path.join(BASE_DIR, ‘db.sqlite3‘),    ‘ENGINE‘: ‘django.db.backends.mysql‘,    ‘NAME‘:‘xiaoshuo‘,    ‘USER‘: ‘xiaoshuo‘,    ‘PASSWORD‘: ‘qiangzi()‘,    ‘HOST‘: ‘mysql.litianqiang.com‘,    ‘PORT‘: ‘7150‘,    }}

2、模版

TEMPLATE_DIRS = (        os.path.join(BASE_DIR,‘templates‘),    )

3、靜態檔案

STATICFILES_DIRS = (        os.path.join(BASE_DIR,‘static‘),    )

路由系統

1、每個路由規則對應一個view中的函數

url(r‘^index/(\d*)‘, views.index),url(r‘^manage/(?P<name>\w*)/(?P<id>\d*)‘, views.manage),url(r‘^manage/(?P<name>\w*)‘, views.manage,{‘id‘:333}),

2、根據app對路由規則進行一次分類

url(r‘^web/‘,include(‘web.urls‘)),

url常用匹配文法:
