Laravel / Sentinel - 如何通过 pivot 获取值 table

Question

我使用Sentinel Framework 进行授权和认证。但是我卡在了用户管理中。

我想显示电子邮件 - 角色等详细信息，但我仍然卡在这里。

我的数据库：

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]);
}

我的用户模型

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

那我的看法

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

然后我得到一个错误

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

如果我写

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

它看起来像一个数组

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

但是我无法访问 "slug" 属性 :(

我该怎么做？

非常感谢！！！

用户模型

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

榜样

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]);
}

查看

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