第一课

• Django版本:1.11.2
• Pthon版本:3.6.1

安装

pip install django

开始

创建项目:

django-admin startproject mysite

项目结构:

G:\MYSITE
│  manage.py
│
└─mysite
   │  __init__.py
   │  urls.py
   │  wsgi.py
   └─ settings.py

开发服务器(在 manage.py 文件目录下运行):

python manage.py runserver
python manage.py runserver 8080    #8080端口运行
python manage.py runserver 0:8000  #监听所有网卡ip

创建app:

python manage.py startapp polls

app结构:

polls
│  __init__.py
│  admin.py
│  apps.py
│  models.py
│  tests.py
│  urls.py
├─ views.py
│
└─ migrations
       __init__.py

写第一个view

polls/views.py

from django.http import HttpResponse

def index(request):
    return HttpResponse("Hello, world. You're at the polls index.")

写url指向这个view

polls/urls.py

from django.conf.urls import url
from . import views

urlpatterns = [
    url(r'^$', views.index, name='index'),
]

在root URLconf里调用polls.url模块

mysite/urls.py

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

urlpatterns = [
    url(r'^polls/', include('polls.urls')),
    url(r'^admin/', admin.site.urls),
]

注意: include方法的正则表达式不能以 $ 结尾。
