Ajouter un attribut au coupon de la règle de prix du panier

Existe-t-il un moyen d'ajouter un attribut à une règle de prix de panier dans Magento? Je dois ajouter un champ appelé "en vedette" pour chaque règle de prix de panier et après cela, être capable de filtrer les règles par cet attribut.

J'ai fini par utiliser la réponse musicliftsme . Voici le code complet avec un programme d'installation pour mettre à jour la table salesrule.

Module disponible ici.

1. Installez une nouvelle colonne featureddans la table salesrule.

2. Réécrivez les Mage_Adminhtml_Block_Promo*classes pour mettre à jour l'interface d'administration de cette nouvelle fonctionnalité.

Après cela, vous pouvez filtrer par votre nouvelle colonne.

Dans l'administrateur, accédez à Catalog > Attributes > Manage Attributes, puis ouvrez votre attribut. Sous Frontend Properties, réglez Use for Promo Rule Conditionssur Yes. Cela vous permettra d'utiliser votre attribut dans les règles de prix du panier.
