laravel 5中的Models和Repository有什麼區別？

Question

我想知道laravel 5中Models和Repository之間有什麼區別。兩者是否相同，以及存儲庫的好處是什麼。

Answer 1

模型和存儲庫不相同。

從documentation - Models allow you to query for data in your tables, as well as insert new records into the table.這是什麼意思，是模型打開訪問數據庫表。它還允許您與其他模型進行關聯，以便無需編寫單個查詢即可提取數據。

存儲庫允許您處理模型，而無需在控制器內編寫大量查詢。反過來，如果出現任何錯誤，保持代碼更整潔，模塊化且更易於調試。

您可以通過以下方式使用存儲庫：

public function makeNotification($class, $title, $message) 
{ 
    $notification = new Notifications; 
    ... 
    $notification->save(); 
    return $notification->id; 
} 

public function notifyAdmin($class, $title, $message) 
{ 
    $notification_id = $this->makeNotification($class, $title, $message); 
    $users_roles = RolesToUsers::where('role_id', 1)->orWhere('role_id', 2)->get(); 
    $ids = $users_roles->pluck('user_id')->all(); 
    $ids = array_unique($ids); 
    foreach($ids as $id) { 
     UserNotifications::create([ 
      'user_id' => $id, 
      'notification_id' => $notification_id, 
      'read_status' => 0 
     ]); 
    } 
} 

而且控制器內部：

protected $notification; 

public function __construct(NotificationRepository $notification) 
{ 
    $this->notification = $notification; 
} 

public function doAction() 
{ 
    ... 
    $this->notification->notifyAdmin('success', 'User Added', 'A new user joined the system'); 
    ... 
}
