从资源模板Laravel 7和8中排除字段

Question

我遇到了一个从控制器CompanyController.php中的资源集合中筛选字段的解决方案

例如，下面的代码返回除company_logo之外的所有值

CompanyResource::collection($companies)->hide(['company_logo']);

CompanyResource.php

<?php

namespace App\Http\Resources;

use Illuminate\Http\Resources\Json\JsonResource;


class CompanyResource extends JsonResource
{
    /**
     * Transform the resource into an array.
     *
     * @param  \Illuminate\Http\Request  $request
     * @return array
     */

    protected $withoutFields = [];

    public static function collection($resource)
    {
        return tap(new CompanyResourceCollection($resource), function ($collection) {
            $collection->collects = __CLASS__;
        });
    }

    // Set the keys that are supposed to be filtered out
    public function hide(array $fields)
    {
        $this->withoutFields = $fields;
        return $this;
    }

    // Remove the filtered keys.
    protected function filterFields($array)
    {
        return collect($array)->forget($this->withoutFields)->toArray();
    }

    public function toArray($request)
    {
        return $this->filterFields([
            'id' => $this->id,
            'name' => $this->name,
            'email' => $this->email,
            'telephone' => $this->telephone,
            'company_logo' => $this->company_logo,
            'social_links' => $this->social_links,
            
        ]);
    }

}

现在，在我的UserResource中，我仍然希望指定不希望从同一个CompanyResource返回的字段，但它在UserResource中不再是一个集合

UserResource.php

public function toArray($request)
    {
        return [
            'id' => $this->id,
            'email' => $this->email,
            'status' => $this->status,
            'timezone' => $this->timezone,
            'last_name' => $this->last_name,
            'first_name' => $this->first_name,
            'tags' => TagResource::collection($this->whenLoaded('tags')),
            'company' => new CompanyResource($this->whenLoaded('company')),
            
        ];
    }

所以我的想法是能够在'company' => new CompanyResource($this->whenLoaded('company')),上指定排除的字段，这些字段已经在这里停留了一段时间。

Answer 1

经过研究，我为我的问题找到了一个可行的解决方案

'company' => CompanyResource::make($this->whenLoaded('company'))->hide(['company_logo']),

而不是我不能灵活使用的以下代码：

'company' => new CompanyResource($this->whenLoaded('company')),
