用django写一个简单的网页页面

django

python

一、创建django项目先创建一个项目为testweb，创建一个应用为hello在dos的命令如下E:\>django-admin-script.py startproject testwebE:\>cd testwebE:\testweb>django-admin-script.py startapp hello注意命令和字母大小写

二、修改testweb的settings.py的参数找到INSTALLED_APPS项，在此项添加hello如下：INSTALLED_APPS = [    'django.contrib.admin',    'django.contrib.auth',    'django.contrib.contenttypes',    'django.contrib.sessions',    'django.contrib.messages',    'django.contrib.staticfiles', 'hello',]

三、定义hello的view的视图函数打开testweb，打开hello文件夹，找到viewspy修改如下：#coding:utf-8from django.http import HttpResponsefrom django.shortcuts import render def index(request):    return HttpResponse('欢迎打开django的大门')注意：python的缩进问题

四、修改testweb的URL参数打开testweb的子目录testweb，找到urls.py修改如下from django.conf.urls import urlfrom django.contrib import adminfrom hello import views as hello_viewsurlpatterns = [    url(r'^admin/', admin.site.urls), url(r'^$',hello_views.index),]

五、检查结果和查看进入DOS下，打开testweb目录，运行命令manage.py runserver如下：E:\django\testweb>manage.py runserverPerforming system checks...System check identified no issues (0 silenced).You have 13 unapplied migration(s).
