    $this->promotion->getWhereAll(['group_type' => 'R2']) is get PromotionRepo

    <?php
namespace AppRepositoriesroda2;
use AppModelsCarousel;
use AppRepositoriesAppEloquent;

class PromotionRepo extends AppEloquent
{
    protected $model;
    public function __construct(Carousel $model)
    {
        $this->model = $model;
    }
}

    carousel models

    <?php

namespace AppModels;

use IlluminateDatabaseEloquentFactoriesHasFactory;
use IlluminateDatabaseEloquentModel;

class Carousel extends Model
{
    use HasFactory;
    protected $table = 'carousels';
    protected $fillable = [
        'user_id',
        'state',
        'img',
        'group_type',
    ];
}

    We don’t know what $this->promotion->getWhereAll(['group_type' => 'R2']) actually returns, but the return of the index function inside the controller class should be something like

    return view('frontend.carousel', ['sliders'=>$sliders]);
