Помогите доработать модуль новостей

[mastdai]

Возникла необходимость выводить для заполнения поле "date_added" при добавлении новости.

Модуль "Последние Новости". Хотелось бы, чтобы вылезал календарик, но можно и просто поле для заполнения + нужно, чтобы по умолчанию стояла текущая дата.

Данное поле уже присутствует в таблице, его необходимо вывести в админку для изменения

так выглядит код из каталога /admin/model/fido/

<?php
class ModelFidoNews extends Model {
