Laravel 分形转换器 - 没有包含

Question

我在 laravel 5.3 中使用分形包。我有一个与视频有 hasMany 关系的播放器模型，因此一个播放器有很多视频。

播放器模型:

public function videos()
  {
      return $this->hasMany(Video::class);
  }

视频模型:

public function player()
{
    return $this->belongsTo(Player::class);
}

我正在尝试发送播放器数据并在其中包含视频数据。这是 Controller 中的代码:

            $player  =  fractal()
                       ->item($player)
                       ->parseIncludes(['videos'])
                       ->transformWith(new PlayerTransformer)
                       ->toArray();

这是PlayerTransformer:

<?php

namespace App\Transformer;

use App\Player;

class PlayerTransformer extends \League\Fractal\TransformerAbstract
{
    protected $availableIncludes = [
        'videos'
    ];

    public function transform(Player $player)
    {
        return [
          'id' => $player->id,
          'first_name' => $player->first_name,
          'last_name' => $player->last_name,
          'image' => $player->image_filename,
          'club' => $player->club,
          'birthday' => $player->birthday,
        ];
    }

    public function includeVideos(Player $player)
    {
        $videos = $player->videos()->where('processed', 1)->get();

        return $this->collection($videos, new VideoTransformer);
    }
}

我正在获取播放器数据，但没有获取视频的任何信息。这行不通，但如果用视频尝试更奇怪，我什至没有在其转换器中包含函数:

<?php

namespace App\Transformer;

use App\Video;

class VideoTransformer extends \League\Fractal\TransformerAbstract
{
    public function transform(Video $video)
    {
        return [
          'id' => $video->id,
          'uid' => $video->uid,
          'title' => $video->title,
          'image' => $video->getThumbnail(),
          'description' => $video->description,
          'views' => $video->viewCount(),
          'created_at' => $video->created_at->diffForHumans(),
        ];
    }
}

但是，当我尝试在此处包含播放器数据时，它起作用了:

              $videos = fractal()
                        ->collection($videos)
                        ->parseIncludes(['player'])
                        ->transformWith(new VideoTransformer)
                        ->toArray();

然后我尝试应用与视频转换器相同的设置并删除播放器转换器中的 $availableIncludes 和 includeVideos，但它再次没有在那里工作。我做错了什么？

我在没有身份验证的情况下执行 get 来测试我的 Controller ，它给出了错误:

PHP fatal error :第 8 行/app/Transformers/CustomerCategoryTransformer.php 中的 App\Transformers\CustomerCategoryTransformer::$availableIncludes 类型必须是数组(如类 League\Fractal\TransformerAbstract 中)

我注释掉了这行:

protected $defaultIncludes = [];
protected $availableIncludes = [];

我的代码:

<?php

namespace App\Transformers;

use App\Models\CustomerCategory;
use League\Fractal\TransformerAbstract;

class CustomerCategoryTransformer extends TransformerAbstract
{
    // protected $defaultIncludes = [];

    // protected $availableIncludes = [];

    public function transform(CustomerCategory $model)
    {
        return [
            'id' => $model->id,
            'uuid' => $model->uuid,
            'seq' => $model->seq,
            'slug' => $model->slug,
            'name' => $model->name,
            'active' => $model->active,
            'created_at' => $model->created_at->toDateTimeString(),
            'updated_at' => $model->updated_at->toDateTimeString(),
        ];
    }
}
