2.3.3
1、创建一个名叫polls的app
python3. manage.py startapp polls
tree mysite/
mysite/
├── db.sqlite3
├── manage.py
├── mysite
│ ├── __init__.py
│ ├── __pycache__
│ │ ├── __init__.cpython-.pyc
│ │ ├── settings.cpython-.pyc
│ │ ├── urls.cpython-.pyc
│ │ └── wsgi.cpython-.pyc
│ ├── settings.py
│ ├── urls.py
│ └── wsgi.py
└── polls
├── admin.py
├── apps.py
├── __init__.py
├── migrations
│ └── __init__.py
├── models.py
├── tests.py
└── views.py
2、给polls这个app编写一个视图、也就是为polls/views.py 中增加相应输出html的文件；修改后polls/views.py 的内容如下：
from django.shortcuts import render
from django.http import HttpResponse
# Create your views here. def index(request):
return HttpResponse("this is polls.index")
3、为视图关联一个url，这样通过这个url就能访问这个视图了；于是在pollsg下创建一个urls.py文件；
polls/urls.py 的内容如下：
from django.conf.urls import url
from . import views urlpatterns=[
url(r'^$',views.index,name='index'),
]
4、把polls的url配置增加到整个project的url配置中去，所以把mysite/urls.py 文件的内容改成如下：
"""mysite URL Configuration The `urlpatterns` list routes URLs to views. For more information please see:
https://docs.djangoproject.com/en/1.10/topics/http/urls/
Examples:
Function views
1. Add an import: from my_app import views
2. Add a URL to urlpatterns: url(r'^$', views.home, name='home')
Class-based views
1. Add an import: from other_app.views import Home
2. Add a URL to urlpatterns: url(r'^$', Home.as_view(), name='home')
Including another URLconf
1. Import the include() function: from django.conf.urls import url, include
2. Add a URL to urlpatterns: url(r'^blog/', include('blog.urls'))
"""
from django.conf.urls import url,include # 这里还要增加include的引用
from django.contrib import admin urlpatterns = [
url(r'^polls/', include('polls.urls')), #注意include的参数中用的是 ‘.’号而不是目录分隔'/'
url(r'^admin/', admin.site.urls),
]
5、测试能不能访问到polls/view/index这个视图
