can we use model relationships in db result in laravel code example

Example 1: laravel eloquent relationships

<?php

namespace App\Models;

use Illuminate\Database\Eloquent\Model;

class Project extends Model
{
    /**
     * Get all of the deployments for the project.
     */
    public function deployments()
    {
        return $this->hasManyThrough(Deployment::class, Environment::class);
    }
}

Example 2: eloquent relationships

$roles = App\User::find(1)->roles()->orderBy('name')->get();
