Laravel隐藏或从结果中删除一些数据库列数据

标签: php laravel

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

,它们是可选的,因此我无法将此字段设置为自模型,现在我将此类用作ManageResourcehode/remove的字段/列,例如以下代码:

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

使用由下面的类实现的代码后,我在数组键上只得到idemail,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();
    }
}

由于您希望将某些通常可见的属性隐藏在给定的模型实例上,因此可以使用makeHidden方法。

  

返回$ user-> makeHidden('attribute')-> toArray();

     

在这里,$ user代表用户模型

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;

您的情况:

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

$result = User::whereApiToken($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']);

您的情况

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

最简单的方法不是在模型本身上使用setHidden()方法吗?

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

echo $user;

给出表/字段结构id - email - user_id,结果应为:

{"user_id": 1}

User::select('name')->get();
User::select('name', 'email')->get();
User::all()->pluck('name'); // array

尝试一下:

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

您可以使用get()

$result = new (ManageResource($user))->get(['name']);

它将仅返回所需的值。

您可以使用地图过滤器获取所需字段。

$events= Events::where(['id' => 1])->get()
            ->map(function ($event) {
                return [
                    'id' => $event->id,
                    'title' => $event->title,
                    'target' => $event->specific,
                    'date' => $event->start . '-' . $event->end,
                    'created' => $event->created_at
                ];
            });

$_SESSION['data'] = array();
   $rows= Product::with('category')->get()
        ->map(function ($rows) {
            array_push($_SESSION['data'],array(
                'id' => $rows->id,
                'title' => $rows->title,
                'price' => $rows->price,
                'photo' => $rows->price,
                'categorytitle' => $rows->category->title,
                'created_at' => $rows->getCreationDate(),
                'updated_at' => $rows->getUpdationDate(),

            ));
        });
   $data = $_SESSION['data'];
   unset($_SESSION['data']);
   return view("products")->with("result",$data);
