In your User class add
在您的 User 类中添加
public function roles()
{
return $this->belongsToMany('Role','assigned_roles');
}
Then you can get all roles for a specific user
然后您可以获得特定用户的所有角色
$user = User::with('roles')->find(1);
$roles = $user->roles;

If you are using Zizaco\Entrust you don't need new roles method in User model. Roles method already exist in EntrustUserTrait class. You only need this line inside User class:
如果您使用的是 Zizaco\Entrust，则不需要用户模型中的新角色方法。Roles 方法已存在于 EntrustUserTrait 类中。您只需要 User 类中的这一行：
use EntrustUserTrait;
like this:
像这样：
<?php
namespace App;
use Illuminate\Foundation\Auth\User as Authenticatable;
use Zizaco\Entrust\Traits\EntrustUserTrait;
class User extends Authenticatable
{
use EntrustUserTrait; // add this trait to your user model
.....
}
In your UsersController you can select users with their roles (index method):
在您的 UsersController 中，您可以选择具有角色的用户（索引方法）：
<?php
namespace App\Http\Controllers;
use App\User;
use Illuminate\Http\Request;
use App\Http\Requests;
class UsersController extends Controller
{
protected $users;
public function __construct(User $users)
{
$this->users = $users;
parent::__construct();
}
public function index()
{
$users = $this->users->with('roles')->paginate(25);
return view('users.index', compact('users'));
}
In your blade loop $user->roles inside $users loop because $user->roles are collection even if user have only one role.
在您的刀片循环 $user->roles 内 $users 循环中，因为即使用户只有一个角色， $user->roles 也是集合。
@foreach($users as $user)
@foreach($user->roles as $role)
{{ $role->display_name }}
@endforeach
@endforeach
