Laravel 5.1,Dingo - 嵌套变形金刚

是否有一种优雅的方式来嵌套变形金刚以供关系使用?我正在构建一个REST接口,允许集合有条件地包含关系模型。到目前为止,我已经取得了一定的成功,但在变形金刚方面似乎有所分析(我承认我对Laravel 5.1和Dingo有点新意)。我希望尽可能保持干燥,这样如果将来关系或属性发生变化,很容易改变。

例如,用户可能收到一条或多条消息的简单场景(用户已收到许多消息)我可以在UserTransformer中执行以下操作:

<?php

namespace App\Transformers;

use App\Models\User;
use League\Fractal;

class UserTransformer extends Fractal\TransformerAbstract
{
    public function transform(User $user)
    {
        // Transform the basic model
        $returnUser = [
            'id'           => (int) $user->id,
            'email'        => $user->email,
            'role'         => $user->role,
            'status'       => $user->status,
            'links'        => [
                [
                    'rel' => 'self',
                    'uri' => '/users/'.$user->id
                ]
            ]
        ];

        // Transform relationships, but only if they exist and are requested
        if (isset($user->receivedMessages))
        {
            $returnUser['received_messages'] = [];

            foreach ($user->receivedMessages as $msg)
            {
                $returnUser['received_messages'][] = [
                    'id'      => $msg->id,
                    'read'    => $msg->read,
                    'content' => $msg->content
                ];
            }
        }
        return $returnUser;
    }
}

在这种情况下,我希望将MesagesTransformer嵌套/应用于相关的接收消息以进行输出格式化,以便所有REST输出在所有关系中保持一致。这可能吗?谢谢!
