Example:

/**
 * @property integer $Id
 * @property integer $ResidentId
 * @property string $Drug
 * @property string $Strength
 * @property string $Barcode
 * @property string $Directions
 * @property string $Notes
 * @property integer $FillDateDay
 * @property integer $FillDateMonth
 * @property integer $FillDateYear
 * @property boolean $OTC
 * @property DateTime $Created
 * @property DateTime $Updated
 * @property DateTime $deleted_at
 *
 * @mixin Builder
 */

    public const FIELDS = [

        'ResidentId' => 'integer',
        'UserId' => 'integer',
