laravel 5.4中的政策有什么问题？

Question

我在laravel 5.4中遇到了授权政策的问题。我的代码如下所示：

ManagerPolicy.php

<?php

namespace App\Policies;

use App\Models\User;
use App\Models\Manager;
use Illuminate\Auth\Access\HandlesAuthorization;
use Illuminate\Support\Facades\Auth;

class ManagerPolicy
{
    use HandlesAuthorization;

    public function view(Manager $manager)
    {
      echo 1;
      die;
      return $manager->hasAccess('manages.view');
    }
}
?>

AuthServiceProvider.php

<?php

namespace App\Providers;


use App\Models\Manager;
use App\Policies\ManagerPolicy;
use Illuminate\Support\Facades\Gate;
use Illuminate\Foundation\Support\Providers\AuthServiceProvider as ServiceProvider;

class AuthServiceProvider extends ServiceProvider
{
    /**
     * The policy mappings for the application.
     *
     * @var array
     */
    protected $policies = [
        'App\Model'  => 'App\Policies\ModelPolicy',
        Manager::class => ManagerPolicy::class
    ];

    /**
     * Register any authentication / authorization services.
     *
     * @return void
     */
    public function boot(Gate $gate)
    {
        $this->registerPolicies($gate);
        //
    }
}
?>

在我的刀片模板视图中

 @can('view', App\Models\Manager::class)
        <li>
          <a href="{!! route('manages.index') !!}">
            <i class="fa fa-user-o"></i> <span> Manager </span>
          </a>
        </li>
      @endcan

当我在“ManagerPolicy @ view”中运行die()命令时，它对我不起作用。
