Laravel 5 Authorization using controller and middleware -

i'm trying make authorization using policy , middleware. wrote model called absence, policy called routepolicy, registered in authserviceprovider.

i wrote route (i'm using dingo / suppose if i've been using route::get have been same):

    $dingoapi->get('absence/{user}','absencecontroller@index')->middleware('can:view,user'); 

it turns out right policy never called, seems laravel isn't able make link absencepolicy.

what going wrong?

here code excerpts of relevant classes:

class absencepolicy {     use handlesauthorization;      protected function authorize($user) {         return auth::user() == $user.id;     }     /**    * determine whether user can view absence.    *    * @param  \app\user  $user    * @param  \app\absence  $absence    * @return mixed    */    public function view(user $user, absence $absence)    {        //        return authorize($user);    } ... 

authserviceprovider

class authserviceprovider extends serviceprovider {   /**    * policy mappings application.    *    * @var array    */    protected $policies = [       'app\model' => 'app\policies\modelpolicy',       'app\absence' => 'app\policies\absencepolicy',       'app\user' => 'app\policies\absencepolicy',    ];    /**    * register authentication / authorization services.    *    * @return void    */   public function boot()   {     $this->registerpolicies();   ....
