1、创建一个名叫polls的app
python3.5 manage.py startapp polls
tree mysite/ mysite/ ├── db.sqlite3 ├── manage.py ├── mysite │ ├── __init__.py │ ├── __pycache__ │ │ ├── __init__.cpython-35.pyc │ │ ├── settings.cpython-35.pyc │ │ ├── urls.cpython-35.pyc │ │ └── wsgi.cpython-35.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
