namespace App\Models;

use CodeIgniter\Model;

class AdministratorModel extends Model
{
 // Validation
 protected $validationRules      = 'administrators';
 protected $validationMessages  = [];
 protected $skipValidation      = false;

{
parent::initController($request, $response, $logger);
$this->model = model("App\Models\AdministratorModel");
}

/**

*
* @return mixed
*/
public function create()
{
$data = $this->request->getPost();

echo '<pre>';
print_r($this->model->save($data));
echo '</pre>';die;
}
} 


To store your validation rules, simply create a new public property in the Config\Validation class with the name of your group.

ohh i see, sorry I misunderstood, Is there another way to store validation rules per file?

The validation rule is an array.
See https://codeigniter.com/user_guide/model...validation

You can get it from another class like Administrators
and set it to the property.
