Додати атрибут у кошик для купона

Чи є спосіб додати атрибут до Правила цін у кошику для покупок у Магенто? Мені потрібно додати поле під назвою "Вибране" для кожного правила цін на кошик і після цього мати можливість фільтрувати правила за цим атрибутом.

Я в кінцевому підсумку використовував відповідь musicliftsme . Ось повний код із інсталятором для оновлення таблиці Salesrule.

Модуль доступний тут.

1. Встановіть новий стовпець featuredдо таблиці salesrule.

2. Перезапишіть Mage_Adminhtml_Block_Promo*класи, щоб оновити адміністраторський інтерфейс для цієї нової функції.

Після цього ви можете фільтрувати за новим стовпцем.

У адміністраторі перейдіть до Catalog > Attributes > Manage Attributes, а потім відкрийте свій атрибут. Під Frontend Properties, встановлено Use for Promo Rule Conditionsна Yes. Це дозволить вам використовувати свій атрибут у правилах цін на кошик для покупок.
