3. 创建APP
cd mysite python manage.py startapp cmdb ################################### cmdb目录 │ admin.py # 后台管理配置模块 │ apps.py # │ models.py # 数据库管理配置模块 │ tests.py # 单元测试模块 │ views.py # 处理用户请求模块
4. 编写代码
urls.py
from django.conf.urls import url
from django.contrib import admin
from cmdb import views
urlpatterns = [
# url(r‘^admin/‘, admin.site.urls),
url(r‘^index/‘, views.index),
]
view.py 函数
from django.shortcuts import render
from django.shortcuts import HttpResponse
