php-Laravel隐藏或从结果中删除一些数据库列数据

在Laravel API中,我有一些方法,它们返回一些我不想在结果中出现的字段,例如：

id  -  email  -  user_id

并且它们是可选的,并且我无法将此字段设置为自模型,现在我将此类用作ManageResource来从类似以下代码的结果中隐藏/删除字段/列：

$user = User::whereApiToken($request->api_token)->first();
$result = ManageResource::make($user)->hide(['id','email']);

在使用下面的类实现的代码后,我仅获得ID和关于数组键的电子邮件,但是我想隐藏它们

ManageResource类：

namespace App\Http\Resources;
use Illuminate\Http\Resources\Json\Resource;

class ManageResource extends Resource
{
    /**
     * @var array
     */
    protected $withoutFields = [];

    /**
     * Transform the resource into an array.
     *
     * @param  \Illuminate\Http\Request
     * @return array
     */
    public function toArray($request)
    {
        return $this->filterFields($this->withoutFields);
    }

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

    /**
     * Remove the filtered keys.
     *
     * @param $array
     * @return array
     */
    protected function filterFields($array)
    {
        return collect($array)->toArray();
    }
}

解决方法:

由于您希望隐藏给定模型实例上的一些通常可见的属性,因此可以使用makeHidden方法.

return $user->makeHidden(‘attribute’)->toArray();

Here, $user represents user model

示例案例：使用带有代码的makeHidden隐藏分页结果中的列

$result = Job::where('user_id','=',Auth::id())->paginate(5);
$data =$result;
$result= $result->makeHidden(['hasMessage']);
$data->data = $result;
return $data;

就您而言：

$result = ManageResource::make($user)->makeHidden(['id','email'])->toArray();
$data->data = $result;
return $data;

要么

$result = User::whereApiToken($request->api_token)->first()->setHidden(['id', 'email']);
$data->data = $result;
return $data;

注意 ：

据我所知,makeHidden不会影响关系.如果允许您将关系中的属性指定为-makeHidden([‘relation.field’]),那会很好.或者,您可以使用以下代码

App\Models\Product::with([‘images’ => function ($query) {
$query->select([‘id’,’product_id’,’image_url’,
‘row_id’])->orderBy(‘created_at’, ‘desc’);
}])->get()->makeHidden([‘id’]);

就你而言

$tickets = UserTickets::with(['user', 'reply' => function ($query) use ($user) {
    $query->with('user')->select(['id','Attrib1','Attrib2'])->whereUserId($user->id);
}])->whereTicketNumber($request->ticket_number)->get();
