8-1 建立管理買家的後台控制器

1. Laravel-Admin 的控制器建立方式與普通的控制器建立方式不太一樣，要用 admin:make 來建立：

   php artisan admin:make UserController --model=App\User

   提醒一下，如果是在Linux下，要寫成這樣：

   php artisan admin:make UserController --model=App\\User

    

2. 其中 --model=App\User 代表新建立的這個控制器是要對 App\User 這個資料模型做增刪改查。
3. 上面指令會自動建立出後台的控制器：\專案\app\Admin\Controllers\UserController.php，內容如下：

   <?php
   
   namespace App\Admin\Controllers;
   
   use App\User;
   use App\Http\Controllers\Controller;
   use Encore\Admin\Controllers\HasResourceActions;
   use Encore\Admin\Form;
   use Encore\Admin\Grid;
   use Encore\Admin\Layout\Content;
   use Encore\Admin\Show;
   
   class UserController extends Controller
   {
       use HasResourceActions;
   
       /**
        * Index interface.
        *
        * @param Content $content
        * @return Content
        */
       public function index(Content $content)
       {
           return $content
               ->header('Index')
               ->description('description')
               ->body($this->grid());
       }
   
       /**
        * Show interface.
        *
        * @param mixed $id
        * @param Content $content
        * @return Content
        */
       public function show($id, Content $content)
       {
           return $content
               ->header('Detail')
               ->description('description')
               ->body($this->detail($id));
       }
   
       /**
        * Edit interface.
        *
        * @param mixed $id
        * @param Content $content
        * @return Content
        */
       public function edit($id, Content $content)
       {
           return $content
               ->header('Edit')
               ->description('description')
               ->body($this->form()->edit($id));
       }
   
       /**

       public function create(Content $content)
       {
           return $content
               ->header('Create')
               ->description('description')
               ->body($this->form());
       }
   
       /**
