Cake 3.x Constants in Model

Hi,
I want to create constants in model.
I want to access them in table and entity.

Now I create them in Entity and when I need them in Table I call newEntity() to access them.
I guess there is another - better way.

Example:
here are the constants decalred int the entity.
class Banners extends Entity{
use ThumbTrait;

const IMG_FOLDER = ‘banners’;
const UPLOAD_PATH = IMG_DIR . self::IMG_FOLDER;
const THUMB_PATH = self::UPLOAD_PATH . DS . ‘thumb’;
}

I need the same constants in table
class BannersTable extends Table{
public function initialize(array $config){
parent::initialize($config);

$entity = $this->newEntity(); //calling entity to use its constants
$this->addBehavior('UploadFile', [
  'path_thumb' => $entity::THUMB_PATH, //I take constants from entity
  'path_upload' => $entity::UPLOAD_PATH, , //I take constants from entity
  'upload_field' => ['upload_field']
]);

}
}

Is there a better way to use same constants in Entity and Table? - I guess there is

Example code? Without seeing what you’re doing, we would be guessing at what might be good for you.
