Laravel: das Verständnis das "Credentials" Methode Mechanismus

Question

ich die benutzerdefinierte Authentifizierung benötigen, und zwar:

• Benutzerdefinierte Modell und DB-Tabelle für LoginController (gelöst)
• "Order ID" anstelle von E-Mail für die Authentifizierung (gelöst)

Weil ich die credentials Methode Mechanismus nicht verstehen, erhalte ich die Fehlermeldung:

Type error: Argument 1 passed to Illuminate\Auth\EloquentUserProvider::validateCredentials() 
must be an instance of Illuminate\Contracts\Auth\Authenticatable, 
instance of App\Order given, called in C:\OpenServer\domains\sites-in-development.loc\vendor\laravel\framework\src\Illuminate\Auth\SessionGuard.php on line 

<?php 

class LoginController extends Controller { 

    use AuthenticatesUsers; 

    protected $redirectTo; 
    protected $orderAlias; 

    protected $loginView; 

    /* 
     Here I set the order ID as "username". I don't like this method, 
     because it causes the confusion ($username is actually order ID), 
     but don't know the other way yet. 
     REF is just the class with array contains the string values to avoid hardcoding 
    */ 
    protected $username = REF::tables['orders']['fieldNames']['orderId']; 


    public function __construct() { 

     $this->middleware('guest')->except('logout'); 
     $this->loginView = '00_top'; 

    } 


    public function showLoginForm() { 
     // Work properly 
    } 


    public function login(Request $request) { 

     if ($this->hasTooManyLoginAttempts($request)) { 

      $this->fireLockoutEvent($request); 
      return $this->sendLockoutResponse($request); 
     } 


     // manual validation (work properly) 
     // getting $orderAlias from DB 

     $redirectTo = '/'.$orderAlias; 

     if ($this->attemptLogin($request)) { 
      return $this->sendLoginResponse($request); // to "credentials"... 
     } 

     $this->incrementLoginAttempts($request); 

     return $this->sendFailedLoginResponse($request); 

    } 

    protected function credentials(Request $request) { 

     // here is error 
     return $request->only(REF::forms['loginToOrder']['fieldNames']['orderID'], 
       REF::forms['loginToOrder']['fieldNames']['password']); 
    } 
}

Das Modell Sie verwenden möchten die Authenticatable Schnittstelle/Vertrag umzusetzen hat.
