Python笔记——Django路由系统

1、创建Django程序

django-admin startproject mysite  创建project

python manage.py startapp app01  创建app01
python manage.py startapp app02  创建app02

 

 2、执行DJango程序

进入Project

python manage.py runserver 127.0.0.1:8000

from django.conf.urls import url
from django.contrib import admin
from app01 import views
urlpatterns = [
    url(r'^admin/', admin.site.urls),
    url(r'^home/', views.home),
]

from django.shortcuts import render
from django.shortcuts import HttpResponse

# Create your views here.

def home(request):
    #return "asdf"
    return HttpResponse('OK')

python manage.py runserver 127.0.0.1:8000

 

执行结果

3、Django依赖数据库配置，settings

生成数据库表：

Python manage.py makemigratios   # 生成配置文件
Python manage.py migrate	 # 根据配置文件创建数据库相关

4、admin

Python manage.py createsuperuser
...
	
http://localhost:8000/admin/

admin主要作用：用来快速操作数据库

admin应用：点名系统、单元测试

 5、路由系统

1、静态路由
2、动态路由
     按照顺序，第n个匹配的数据，交给函数的第n个参数，严格按照顺序模板的方法，将匹配的参数，传给指定的形式参数
3、二级路由
	app01
		url.py
	project_name
		URL : app01 -> include("appo1.url)

from django.conf.urls import url,include
from django.contrib import admin
from app01 import views

urlpatterns = [
    url(r'^admin/', admin.site.urls),
    url(r'^home/', views.home),
    url(r'^news/(d+)/(d+)', views.news),    # 传两个参数
    url(r'^page/(?P<n1>d+)/(?P<n2>d+)', views.page),    # 接收两个参数，不按顺序，指定形式参数
    url(r'^app01/', include("app01.urls")),                 # 二级路由
    url(r'^app02/', include("app02.urls")),
]

from django.shortcuts import render
from django.shortcuts import HttpResponse
# Create your views here.

def home(request):
    #return "asd"
    return HttpResponse('App01.home')

def news(request,nid1,nid2):
    #return "asd"
    nid = nid1 + nid2
    return HttpResponse(nid)

def page(request,n1,n2):
    #return "asd"
    nid = n1 + n2
    return HttpResponse(nid)

from django.conf.urls import url
from django.contrib import admin
from app01 import views

urlpatterns = [
    url(r'^home/', views.home),
]

from django.shortcuts import render,HttpResponse

# Create your views here.

def home(request):
    return HttpResponse('app02.home')

from django.conf.urls import url
from django.contrib import admin
from app02 import views

urlpatterns = [
    url(r'^home/', views.home),
]
