删除文件/上传时删除用户

Question

我有我的用户表（名称，电子邮件，密码等），用户可以上传图片，文件或视频。

他们的照片都存储在特定的路径（例如/myproject/app/public/uploads/01/picture.jpg）

我想，如果由用户上传的文件可以在用户的​​行被删除被删除。

最大的问题是，我想删除的数据，该用户上传，当我做php artisan migrate:refresh --seed

我想这对迁移文件2014_..._create_users_table.php：

use Illuminate\Database\Schema\Blueprint; 
use Illuminate\Database\Migrations\Migration; 

use File; 

class CreateUsersTable extends Migration 
{ 
    /** 
    * Run the migrations. 
    * 
    * @return void 
    */ 
    public function up() 
    { 

     Schema::create('users', function (Blueprint $table) { 
      $table->engine = 'InnoDB'; 
      $table->increments('id'); 
      $table->string('name'); 
      $table->string('email')->unique(); 
      $table->string('password'); 
      $table->rememberToken(); 
      $table->timestamps(); 
     }); 
    } 

    /** 
    * Reverse the migrations. 
    * 
    * @return void 
    */ 
    public function down() 
    { 
     Schema::drop('users'); 
     // Deleting ALL the data that the users have uploaded 
     $dir = public_path(). "/uploads/"; 
     File::deleteDirectory($dir, true); 
    } 
} 

但我有以下错误当我尝试执行时php artisan migrate:refresh --seed

[ErrorException] 
The use statement with non-compound name 'File' has no effect 

谢谢你的帮忙！

变化use File;到use Illuminate\Support\Facades\File as File;
