Php 分形嵌套变换，Dingo API，Laravel 5

我试图用以下代码转换票证的集合

public function transform(Ticket $ticket) {
    return [
        'id' => $ticket->id,
        'title' => $ticket->title,
        'status' => $this->transformerMessage($ticket->status),
        'interactions' => 
              $this->collection(
                   $ticket->interactions,
                   new InteractionTransformer(),
                   'interactions'
              )
    ];
}

但是，交互结果总是空的。下面是我得到的一个输出示例：

{
  "data": [
    {
      "id": 1,
      "title": "Earum repudiandae corporis sapiente at odit itaque ratione.",
      "status": "Open",
      "interactions": {}
    },
    {
      "id": 2,
      "title": "Odit impedit vitae quo sit molestiae eius.",
      "status": "Open",
      "interactions": {}
    },
    {
      "id": 3,
      "title": "Fuga cum corrupti ut.",
      "status": "Open",
      "interactions": {}
    }
  ]
}

如果我尝试死亡并转储

$ticket->interactions

变量，我会得到5个项目的集合（这证明变量不是空的）

我做错了什么

感谢您的关注。

集合调用中的$this指的是从TransformerAbstract继承的transformer，TransformerAbstract从资源类型创建集合

尝试将->getData（）添加到末尾，以从Dingo资源集合中提取真实集合

public function transform(Ticket $ticket) {
    return [
        'id' => $ticket->id,
        'title' => $ticket->title,
        'status' => $this->transformerMessage($ticket->status),
        'interactions' => 
              $this->collection(
                   $ticket->interactions,
                   new InteractionTransformer(),
                   'interactions'
              )->getData()
    ];
}

试试这个。引用dingo变换的回调：

public function transform(Ticket $ticket) {
    $output = $ticket->interactions;
    $trans = new InteractionTransformer();
    return [
        'id' => $ticket->id,
        'title' => $ticket->title,
        'status' => $this->transformerMessage($ticket->status),
        'interactions' => 
              $ticket->interactions->transform(
                 function($i) use ($trans) {
                    return $trans->transform($i);
                 }
              )
    ];
}

我试过了，从技术上讲，它是有效的，但是提取的数据没有通过

InteractionTransformer（）

Ooops的

transform

方法。你说得对。错过了。我在上面添加了另一个答案。
