大家好，又见面了，我是你们的朋友全栈君。
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：
代码语言：javascript复制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 %} 以上三个模板都很简单，就是下面的流程：
- extends继承‘base.html’；
{% load staticfiles %}载入静态文件；{% block title %}资产详细{% endblock %}，定制title;{% block css %}，载入当前页面的专用CSS文件；{% block script %}，载入当前页面的专用js文件；- 最后在
{% block content %}中，编写一个当前页面的面包屑导航； - 页面的主体内容在后面的章节进行充实。
四、访问页面
重启CMDB服务器，访问http://192.168.1.100:8000/assets/dashboard/，可以看到下面的页面。
如果你的配色和我的不一样，没关系，都可以调整的。
