linux环境安装django:
sudo pip install django
windows环境安装django:
pip install django
验证django是否安装:
python -m django --version
切换目录到E:\SourceCode,创建新项目,项目名称为:mysite:
django-admin startproject mysite
切换到mysite目录,运行mysite项目:
python manage.py runserver
在mysite项目中,创建polls应用:
python manage.py startapp polls
开始编写第一个页面,打开polls/views.py:
from django.shortcuts import render
from django.http import HttpResponse
# Create your views here.
def index(request):
return HttpResponse("Hello, world. You're at the polls index.")
此时django还不能访问到polls应用的view,因为缺少路由信息,下面要配置路由信息:
新增并打开polls/urls.py:
from django.conf.urls import url from . import views urlpatterns = [
url(r'^$', views.index, name='index'),
]
打开mysite/urls.py:
from django.conf.urls import include, url
from django.contrib import admin urlpatterns = [
url(r'^polls/', include('polls.urls')),
url(r'^admin/', admin.site.urls),
]
添加路由的方法,有几种,根据不同的情况来使用。
第一种(Function views):
1.首先导入view的模块,from . import views
2.在urlpatterns中插入新的路由,url(r'^$', views.index, name='index')
第二种(Class-based views):
1.首先导入view的模块,from other_app.views import Home
2.在urlpatterns中插入新的路由,url(r'^$', Home.as_view(), name='home')
第三种(Including another URLconf):
1.首先导入include()函数,from django.conf.urls import include, url
2.在urlpatterns中插入新的路由,url(r'^polls/', include('polls.urls'))
先初始化mysite项目的数据库:
python manage.py migrate
配置完成后,运行mysite项目:
python manage.py runserver
