Laravel how to make elegant has many?

Question

Laravel

There is a model, it has a one-to-many relationship through a global variable model code:

<?php namespace My\Trading\Models;

use Model;

/**
 * Model
 */
class Groups extends Model
{
    use \October\Rain\Database\Traits\Validation;

    /*
     * Validation
     */
    public $rules = [
    ];

    /*
     * Disable timestamps by default.
     * Remove this line if timestamps are defined in the database table.
     */
    public $timestamps = true;

    /**
     * @var string The database table used by the model.
     */
    public $table = 'trading_groups';

    public $hasMany = [
        'statistics' => ['\My\Trading\Models\Statistics', 'key' => 'groups_id'],
    ];
}

I get the result like this:

(new Groups)->hasMany('\My\Trading\Models\Statistics');

But this, in my opinion, is not the most elegant way, I suspect there is a more beautiful solution, otherwise why write a connection to the $hasMany variable in the model? Or does $hasMany only play a role in October CMS?
How to get the connection result from the controller in the most elegant way?

Answer 1

I did not work with OctoberCMS, but I suspect that this is their trick to indicate links through $hasMany.
All normal people use like this:

public function statistics()
{
  return $this->hasMany(My\Trading\Models\Statistics::class, 'groups_id')
}
