Laravel/Sentinel - 如何通過數據透視表獲取價值

Question

我使用Sentinel Framework進行授權和身份驗證。但我堅持用戶管理。

我想顯示詳細信息，如電子郵件 - 角色，但我仍然堅持在這裏。

我的數據庫：

role: ID, slug, name 
user: ID, Email, ... 
role_users: user_id, role_id 

我的控制器

public function getAll(){ 
    $user = User::all(); 
    return view('admin.user.list',['user'=>$user]); 
} 

我的usermodel

public function Role(){ 
    return $this->belongsToMany('App\Role','role_users','user_id', 'role_id'); 
} 

然後我看來

<?php foreach ($user as $u): ?> 
<tr> 
<td>{{$u->Role->name}}</td> 
</tr> 
<?php endforeach; ?> 

然後，我得到了一個錯誤

Property [slug] does not exist on this collection instance. 

如果我寫

<td>{{$u->Role}}</td> 

它看起來像

[{"id":1,"slug":"admin","name":"admin","permissions":null,"created_at":null,"updated_at":null,"pivot":{"user_id":1,"role_id":1}}] 

一個數組，但我不能訪問到 「塞」 財產:(

我該怎麼做？

非常感謝！

用戶模型

class User extends Model 
    { 
     /** 
     * The roles that belong to the user. 
     */ 
     public function roles() 
     { 
      return $this->belongsToMany('App\Role'); 
     } 
    } 

角色模型

class Role extends Model 
{ 
    /** 
    * The users that belong to the role. 
    */ 
    public function users() 
    { 
     return $this->belongsToMany('App\User'); 
    } 
} 

控制器

public function getAll(){ 
    $user = User::all(); 
    return view('admin.user.list',['user'=>$user]); 
} 

視圖

@foreach ($user as $u) 
    // becuase many to many you need this 
    @foreach ($u->roles as $role) 
     {{$role->name}} 
    @endforeach 
@endforeach
