Mình tìm hiểu về Repository, gặp ngay em bug này. Vẫn chưa tìm được câu trả lời. Mong mọi người giúp đỡ.

Sau đây là một số đoạn code của mình.

1. App\Http\Controllers\HomeController.php:

2. App\Providers\AppServiceProvider.php:

3. App\Repositories\Eloquents\DbBaseRepository.php:

<?php
namespace App\Repositories\Eloquents;

class DbBaseRepository
{
    /**
     * Eloquent model
     */
    protected $model;

    /**
     * @param $model
     */
    function __construct($model)
    {
        $this->model = $model;
    }

    public function basePaginateList($per)
    {
        return $this->model->orderBy('id', 'desc')->paginate($per);
    }

    public function baseCreate($data)
    {
        return $this->model->create($data);
    }

    public function baseUpdate($data, $key, $value)
    {
        $obj = $this->model->where($key, $value)->first();

        return $obj->update($data);
    }

    public function baseDestroy($key, $value)
    {
        return $this->model->where($key, $value)->delete();
    }

    public function baseFindBy($key, $value)
    {
        return $this->model->where($key, $value)->first();
    }

    public function baseFindAllBy($key, $value)
    {
        return $this->model->where($key, $value)->orderBy('id', 'desc')->get();
    }

    {
        return $this->model::where($key, $value)->first($array);
    }
}

5. App\Repositories\Eloquents\DbDishRepository.php:

    }
    public function topLists()
    {
        $result = $this->_model::whereNotNull('id')
            ->orderBy('like_number', 'desc')
            ->take(10)
            ->get();
