创建django的8大步骤xxx.setAttribute('name', 'user'); 添加属性和值 xxx.attr('name') 查看属性的值 $(xxx).addClass 添加样式 $（）.after() 添加在标签后面

第一步.创建django

方法一：django-admin startproject

方法二： 直接在python上创建

第二步：创建工程名cmdb 

python manage.py startapp cmdb(文件名)

第三步:设置静态文件路径

project.settings.py 文件中

STATICFILES_DIRS = (
     os.path.join(BASE_DIR, 'static'）,
)

第四步： 模板路径（在python中直接默认）不用设置

5.setting 中
middlerware
     #注释csrf

6.定义路由规则
在url.py 中实现
如添加
from cmdb import views

url(r'^login/', views.login),

7.定义视图函数
在views.py 
def func(request):
# request 表示接受的数据
request.method: GET/POST
request.POST.get("xxx", None)

return  HttpResponse('字符串')
return render（request, HTML名字）
return redirect（HTML路径）

8.渲染模板 
  特殊的模板语言
   {{变量名}}
def func(request):
    return render(request, 'index.html', {'user_list': 'alex'})

for 循环
{%for row in user_list%}
      <tr>
         <td>{{user_list.username}}</td>
         <td>{{user_list.email}}</td>
      <tr>
{%endfor %}

if 条件语句
{%if %}
{%else%}
{%endif%}

一个功能实现一个登录页面和后台人员的添加删除功能
1.删除功能通过创建一个input标签和赋予按钮submit功能实现
登录功能主要通过redirect('/home/')重新传递数据
通过request.POST.get("xxx", None)获得重新传递的数据 xxx表示name属性的值
再次通过render传递
