该教程是创建一个用于投票的网页。
1.使用命令创建site
进入要创建site的目录，输入命令:
$ django-admin startproject mysite
2.让我们来看看startproject创造了什么：
mysite/
manage.py
mysite/
__init__.py
settings.py
urls.py
wsgi.py
3.步骤1已经创建了一个site，现在启动验证一下：
$ python manage.py runserver
4.创建投票模块
$ python manage.py startapp polls
polls的目录如下：
polls/
__init__.py
admin.py
apps.py
migrations/
__init__.py
models.py
tests.py
views.py
编辑polls页面的内容：
polls/views.py
from django.http import HttpResponse
def index(request):
return HttpResponse("Hello, world. You're at the polls index.")
polls/urls.py
from django.urls import path
from . import views
urlpatterns = [
path('', views.index, name='index'),
]
mysite/urls.py
from django.contrib import admin
from django.urls import include, path
urlpatterns = [
path('polls/', include('polls.urls')),
path('admin/', admin.site.urls),
]
mysite/settings.py 设置当地时区
TIME_ZONE = 'Asia/Shanghai'
重新启动，查看polls页面是否生效：
$ python manage.py runserver
