Django 视图
项目创建
python s.py djangoproject usr_app
创建后的目录截图如下
urls.py设定
#djangoproject的urls.py指向app_user的urls.py--namespace:模块名
from django.conf.urls import include, url
from django.contrib import admin
urlpatterns = [
#app_user
url(r'^', include('app_user.urls',namespace="app_user")),
#admin
url(r'^admin/', include(admin.site.urls)),
]
#app_user内urls.py文件设定该模块的所有路由
from django.conf.urls import include, url
from django.contrib import admin
from . import views
urlpatterns = [
#name--反向解析的名字
url(r'^app_user$', views.test,name="user"),
]
写一个小视图模板进行测试
<!-- 简单的视图模板 -->
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<title>Title</title>
</head>
<body>
<p> 你好：{{ usrname }}</p>
<!-- 使用反向解析，传递的user就是视图中设定的解析路由，即/app_user/ -->
<a herf="{% url 'app_user:user' %}">{% url 'app_user:user' %}</a>
</body>
</html>
app_user:view.py 编写视图，构建上下文，生成html网页，设定cookie值
#coding: utf-8
from django.shortcuts import render
# Create your views here.
from django.http import HttpResponse
def test(request):
#构建上下文
context = dict(
usrname="shihongguang"
)
#render构建要返回的HttpResponse(request,templates,context)
response = render(request, 'app_user/test.html', context)
#HttpResponse设定cookie,后面的都时默认参数，方便后面查看
response.set_cookie("auth",value="shihongguang",max_age=None, expires=None, path='/',
domain=None, secure=False, httponly=False)
#返回构建好的response
return response
修改搜索的模板路径
#模板路径修改
TEMPLATES = [
{
'BACKEND': 'django.template.backends.django.DjangoTemplates',
'DIRS': [os.path.join(BASE_DIR, 'templates')],#增加模板的路径
'APP_DIRS': True,
'OPTIONS': {
'context_processors': [
'django.template.context_processors.debug',
'django.template.context_processors.request',
'django.contrib.auth.context_processors.auth',
'django.contrib.messages.context_processors.messages',
],
},
},
]
启动测试服务器
./manage.py runserver
浏览器运行的结果
