# 1  之前写的首页，登录，课程都是前台（主站）----》后台管理（运营）---》admin自带的---》不好看，不好用

# 2  自己写后台管理    还是    继续使用django的admin来做还是    基于第三方的美化
	-使用第三方的drf+vue的后台管理框架
    -咱们继续使用djagno admin---》第三方的美化---》二次开发
    
# 3 simpleui
	-第一步：安装
    	pip install django-simpleui
     -第二步：在app中注册
    	 INSTALLED_APPS = [
          'simpleui',
              ...
          ]
    -第三步：在配置文件中
    	# 1 指定simpleui默认的主题,指定一个文件名，相对路径就从simpleui的theme目录读
        # 2 默认图标
        # 3 登录页粒子效果
        # 4 定制菜单（重点）
        # 5 隐藏显示服务器信息，快速操作
        
    -第四步：在admin中定制
    	@admin.register(Course)
        class CourseAdmin(admin.ModelAdmin):
            # 当前页面显示的字段
            list_display = ('id', 'name', 'course_type', 'pub_date')

            # 增加自定义按钮
            actions = ['custom_button',]
            def custom_button(self, request, queryset):
                print(queryset)
                print('按钮被点了')

            custom_button.short_description = '测试按钮'
            # custom_button.icon = 'fas fa-audio-description'
            custom_button.type = 'danger'
            custom_button.style = 'color:black;'
            
    -第五步：定制自己的页面
    	就是写前后端混合，配置好链接即可
        
    -第六步：集成监控大屏
    	-从网上找一个模板，样式都引入，写模板语法即可

# 课程详情页面
	-视频播放---》
    -之前用：vue-video-player---》跟node版本兼容性有问题
    -现在新的用：vue-core-video-player 
    
#安装视频播放组件：https://www.jianshu.com/p/df4780086a8b
	#第一步：安装
	cnpm install vue-video-player -S
	#第二步：在main.js导入
    // vue-video播放器
    require('video.js/dist/video-js.css');
    require('vue-video-player/src/custom-theme.css');
    import VideoPlayer from 'vue-video-player'
    Vue.use(VideoPlayer);
    # 第三步：在某个vue组件中使用
       import {videoPlayer} from 'vue-video-player';
       注册
       页面某个位置：
          <videoPlayer class="video-player vjs-custom-skin"
                                 ref="videoPlayer"

                                 @pause="onPlayerPause($event)">
         </videoPlayer>
       # data中进行播放器的配置
       -playerOptions：对象  
    	{
           aspectRatio: '16:9', // 将播放器置于流畅模式，并在计算播放器的动态大小时使用该值。值应该代表一个比例 - 用冒号分隔的两个数字（例如"16:9"或"4:3"）
           sources: [{ // 播放资源和资源格式
               type: "video/mp4",
