这里“Roles hasMany Users”和“Users areTo Roles”

当用户保存时,我们也会询问用户的角色&记录保存.

问题：
我有列firstname,lastname,roles的用户列表.每个&每列都有排序,但角色排序不起作用.

角色表包含​​角色名称的“名称”字段.
我在下面提到了链接,但它对我不起作用.
Pagination Sort in Cakephp 3.x

UsersController：

public function index() {
     $this->paginate = [
                'contain' => ['Roles'],'conditions' => [
                    'Users.user_type <>' => 1
                ]
            ];

            $this->set('users',$this->paginate($this->Users));
            $this->set('_serialize',['users']);
}

index.ctp

<tr>
                <th><?PHP echo $this->Paginator->sort('firstname',__('First Name')) ?></th>
                <th><?PHP echo $this->Paginator->sort('lastname',__('Last Name')) ?></th>
                <th><?PHP echo $this->Paginator->sort('email',__('Email Address')) ?></th>
                <th><?PHP echo $this->Paginator->sort('Roles.name',__('Role Associated')) ?></th>
                <th><?PHP echo $this->Paginator->sort('status',__('status')) ?></th>
                <th class="actions"><?PHP echo __('action') ?></th>
            </tr>

让我知道你有任何解决方案.
