作为CMDB资产管理项目，必须有一个丰富、直观、酷炫的前端页面。

适合运维平台的前端框架有很多，开源的也不少，这里选用的是AdminLTE。

AdminLTE

AdminLTE托管在GitHub上，可以通过下面的地址下载：

https://github.com/almasaeed2010/AdminLTE/releases

AdminLTE自带JQuery和Bootstrap3框架，无需另外下载。

AdminLTE自带多种配色皮肤，可根据需要实时调整。

AdminLTE是移动端自适应的，无需单独考虑。

AdminLTE自带大量插件，比如表格、Charts等等，可根据需要载入。

但是AdminLTE的源文件包内，缺少font-awesome-4.6.3和ionicons-2.0.1这两个图标插件，它是通过CDN的形式加载的，如果网络不太好，加载可能比较困难或者缓慢，最好用本地静态文件的形式。教程在Github的包内附带上了这两个插件，可以直接使用，当然你自己下载安装也行。

一、创建base.html

AdminLTE源文件包里有个index.html页面文件，可以利用它修改出我们CMDB项目需要的基本框架。

在项目的根目录cmdb下新建static目录，在settings文件中添加下面的配置：

STATICFILES_DIRS = [
    os.path.join(BASE_DIR, "static"),
]

为了以后扩展的方便，将AdminLTE源文件包里的bootstrap、dist和plugins三个文件夹，全部拷贝到 static目录中，这样做的话文件会比较大，比较多，但可以防止出现引用文件找不到、插件缺失等情况的发生，等以后对AdminLTE非常熟悉了，可以对static中无用的文件进行删减。

在cmdb根目录下的templates目录下，新建base.html文件，将AdminLTE源文件包中的index.html中的内容拷贝过去。然后，根据我们项目的具体情况修改文件引用、页面框架、title、CSS、主体和script块。nainaitea.com

这是一个适合当前CMDB的精简版本。在Github中，还提供了一个全功能的版本base-backup.html，方便大家扩展修改。

二、创建路由、视图

这里设计了三个视图和页面，分别是：

dashboard：仪表盘，图形化的数据展示
index：资产总表，表格的形式展示资产信息
detail：单个资产的详细信息页面

将assets/urls.py修改成下面的样子：

#!/usr/bin/env python
# -*- coding:utf-8 -*-

from django.conf.urls import url
from assets import views

app_name = 'assets'

urlpatterns = [
    url(r'^report/', views.report, name='report'),
    url(r'^dashboard/', views.dashboard, name='dashboard'),
    url(r'^index/', views.index, name='index'),
    url(r'^detail/(?P<asset_id>[0-9]+)/$', views.detail, name="detail"),
    url(r'^$', views.dashboard),
]

在assets/views.py中，增加下面三个视图：

from django.shortcuts import get_object_or_404

def index(request):

    assets = models.Asset.objects.all()
    return render(request, 'assets/index.html', locals())


def dashboard(request):
    pass
    return render(request, 'assets/dashboard.html', locals())


def detail(request, asset_id):
    """
    以显示服务器类型资产详细为例，安全设备、存储设备、网络设备等参照此例。
    :param request:
    :param asset_id:
    :return:
    """
    asset = get_object_or_404(models.Asset, id=asset_id)
    return render(request, 'assets/detail.html', locals())

注意需要提前from django.shortcuts import get_object_or_404导入get_object_or_404()方法，这是一个非常常用的内置方法。

三、创建模版

1.dashboard.html

在assets目录下创建templates/assets/dashboard.html文件，写入下面的代码：

{% extends 'base.html' %}
{% load staticfiles %}
{% block title %}仪表盘{% endblock %}

{% block css %}

  <!-- Theme style -->
  <link rel="stylesheet" href="{% static 'dist/css/AdminLTE.min.css' %}">
  <!-- AdminLTE Skins. Choose a skin from the css/skins
       folder instead of downloading all of them to reduce the load. -->
  <link rel="stylesheet" href="{% static 'dist/css/skins/_all-skins.min.css' %}">

{% endblock %}


{% block content %}
    <!-- Content Header (Page header) -->
    <section class="content-header">
      <h1>
        仪表盘
        <small>dashboard</small>
      </h1>
      <ol class="breadcrumb">
        <li><a href="#"><i class="fa fa-dashboard"></i> 主页</a></li>
        <li class="active">仪表盘</li>
      </ol>
    </section>

{% endblock %}

{% block script %}
    <!-- AdminLTE App -->
    <!-- SlimScroll 1.3.0 -->
    <script src="{% static 'plugins/slimScroll/jquery.slimscroll.min.js' %}"></script>
    <script src="{% static 'plugins/fastclick/fastclick.js' %}"></script>
    <!-- AdminLTE for demo purposes -->
    <script src="{% static 'dist/js/app.min.js' %}"></script>
    <!-- FastClick -->
    <script src="{% static 'dist/js/demo.js' %}"></script>
    <script src="{% static 'plugins/knob/jquery.knob.js' %}"></script>
    <!-- page script -->
{% endblock %}

2.index.html

在assets目录下创建templates/assets/index.html文件，写入下面的代码：

{% extends 'base.html' %}
{% load staticfiles %}
{% block title %}资产总表{% endblock %}

{% block css %}

<!-- DataTables -->
  <link rel="stylesheet" href="{% static 'plugins/datatables/dataTables.bootstrap.css' %}">
  <!-- Theme style -->
  <link rel="stylesheet" href="{% static 'dist/css/AdminLTE.min.css' %}">
  <!-- AdminLTE Skins. Choose a skin from the css/skins
       folder instead of downloading all of them to reduce the load. -->
  <link rel="stylesheet" href="{% static 'dist/css/skins/_all-skins.min.css' %}">

{% endblock %}

{% block content %}

    <!-- Content Header (Page header) -->
    <section class="content-header">
      <h1>
        资产总表
        <small>assets list</small>
      </h1>
      <ol class="breadcrumb">
        <li><a href="#"><i class="fa fa-dashboard"></i> 主页</a></li>
        <li class="active">资产总表</li>
      </ol>
    </section>

{% endblock %}

{% block script %}
    <!-- DataTables -->
    <script src="{% static 'plugins/datatables/jquery.dataTables.min.js' %}"></script>
    <script src="{% static 'plugins/datatables/dataTables.bootstrap.min.js' %}"></script>
    <!-- SlimScroll -->
    <script src="{% static 'plugins/slimScroll/jquery.slimscroll.min.js' %}"></script>
    <!-- FastClick -->
    <script src="{% static 'plugins/fastclick/fastclick.js' %}"></script>
    <!-- AdminLTE App -->
    <script src="{% static 'dist/js/app.min.js' %}"></script>
    <!-- AdminLTE for demo purposes -->
    <script src="{% static 'dist/js/demo.js' %}"></script>
    <!-- page script -->
{% endblock %}

3.detail.html

在assets目录下创建templates/assets/detail.html文件，写入下面的代码：

{% extends 'base.html' %}
{% load staticfiles %}
{% block title %}资产详细{% endblock %}
{% block css %}

  <!-- Theme style -->
  <link rel="stylesheet" href="{% static 'dist/css/AdminLTE.min.css' %}">
  <!-- AdminLTE Skins. Choose a skin from the css/skins
       folder instead of downloading all of them to reduce the load. -->
  <link rel="stylesheet" href="{% static 'dist/css/skins/_all-skins.min.css' %}">

{% endblock %}

{% block content %}

    <!-- Content Header (Page header) -->
    <section class="content-header">
      <h1>
        资产详细
        <small>asset info</small>
      </h1>
      <ol class="breadcrumb">
        <li><a href="#"><i class="fa fa-dashboard"></i> 主页</a></li>
        <li>资产总表</li>
        <li class="active">资产详细</li>
      </ol>
    </section>

{% endblock %}

{% block script %}
    <!-- SlimScroll -->
    <script src="{% static 'plugins/slimScroll/jquery.slimscroll.min.js' %}"></script>
    <!-- FastClick -->
    <script src="{% static 'plugins/fastclick/fastclick.js' %}"></script>
    <!-- AdminLTE App -->
    <script src="{% static 'dist/js/app.min.js' %}"></script>
    <!-- AdminLTE for demo purposes -->
    <script src="{% static 'dist/js/demo.js' %}"></script>
    <!-- page script -->
{% endblock %}
