视图和路由
1.创建一个django_test应用

2.setting中设置django_test
INSTALLED_APPS = [
'django.contrib.admin',
'django.contrib.auth',
'django.contrib.contenttypes',
'django.contrib.sessions',
'django.contrib.messages',
'django.contrib.staticfiles',
'django_test.apps.DjangoTestConfig'
]
3.在django_test中的view.py中写视图函数
from django.shortcuts import render
# Create your views here.
from django.http import HttpResponse
def index(request):
return HttpResponse('欢迎来到Gaidy博客')
4.django_test中创建一个urls.py文件用来关联Django目录下的urls.py
from django.conf.urls import url
from . import views
urlpatterns = [
# 这边定义子应用的路由
url(r'index/$',views.index)
]
5.Django目录下的urls.py的设置
from django.conf.urls import url,include
from django.contrib import admin
import django_test.urls
urlpatterns = [
url(r'^admin/', admin.site.urls),
url(r'',include(django_test.urls))
]
6.运行程序

返回html页面
1.在templates创建一个index.html页面
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<title>Gaidy</title>
</head>
<body>
这是一个页面
</body>
</html>
2.views.py视图函数修改
from django.shortcuts import render
# Create your views here.
from django.http import HttpResponse
from django.shortcuts import render
def index(request):
return render(request, 'index.html')
# return HttpResponse('欢迎来到Gaidy博客')
3.运行结果

视图模板
1.前端页面
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<title>Gaidy</title>
</head>
<body>
{{ string }}
</body>
</html>
2.修改view.py代码
from django.shortcuts import render
# Create your views here.
from django.http import HttpResponse
from django.shortcuts import render
def index(request):
date = "我是来自北方的一条狼"
return render(request, 'index.html', {"string":date})
# return HttpResponse('欢迎来到Gaidy博客')
3.运行结果
