python路由韌體_Python筆記——Django路由系統

1、建立Django程式

django-admin startproject mysite 建立project

python manage.py startapp app01 建立app01

python manage.py startapp app02 建立app02

2、執行DJango程式

進入Project

python manage.py runserver 127.0.0.1:8000

from django.conf.urls importurlfrom django.contrib importadminfrom app01 importviews

urlpatterns=[

url(r'^admin/', admin.site.urls),

url(r'^home/', views.home),

]

urls

from django.shortcuts importrenderfrom django.shortcuts importHttpResponse#Create your views here.

defhome(request):#return "asdf"

return HttpResponse('OK')

views

python manage.py runserver 127.0.0.1:8000

執行結果

3、Django依賴資料庫配置，settings

生成資料庫表：

Python manage.py makemigratios # 生成配置檔案

Python manage.py migrate # 根據配置檔案建立資料庫相關

4、admin

Python manage.py createsuperuser

...

http://localhost:8000/admin/

admin主要作用：用來快速操作資料庫

admin應用：點名系統、單元測試

5、路由系統

1、靜態路由

2、動態路由

按照順序，第n個匹配的資料，交給函式的第n個引數，嚴格按照順序模板的方法，將匹配的引數，傳給指定的形式引數

3、二級路由

app01

url.py

project_name

URL : app01 -> include("appo1.url)

1 from django.conf.urls importurl,include2 from django.contrib importadmin3 from app01 importviews4

5 urlpatterns =[6 url(r'^admin/', admin.site.urls),7 url(r'^home/', views.home),8 url(r'^news/(\d+)/(\d+)', views.news), #傳兩個引數

9 url(r'^page/(?P\d+)/(?P\d+)', views.page), #接收兩個引數，不按順序，指定形式引數

10 url(r'^app01/', include("app01.urls")), #二級路由

11 url(r'^app02/', include("app02.urls")),12 ]

one\urls.py

from django.shortcuts importrenderfrom django.shortcuts importHttpResponse#Create your views here.

defhome(request):#return "asd"

return HttpResponse('App01.home')defnews(request,nid1,nid2):#return "asd"

nid = nid1 +nid2returnHttpResponse(nid)defpage(request,n1,n2):#return "asd"

nid = n1 +n2return HttpResponse(nid)

app01\views.py

from django.conf.urls importurlfrom django.contrib importadminfrom app01 importviews

urlpatterns=[

url(r'^home/', views.home),

]

app01\urls.py

1 from django.shortcuts importrender,HttpResponse2

3 #Create your views here.

4

5 defhome(request):6 return HttpResponse('app02.home')

app02\views.py

1 from django.conf.urls importurl2 from django.contrib importadmin3 from app02 importviews4

5 urlpatterns =[6 url(r'^home/', views.home),7 ]

app02\urls.py
