Мне удастся получить поля «Контакт» на странице visualforce, используя backbone.js. Я хочу показывать как поля учетной записи, так и поля контакта одновременно и на одной странице. Для этого следует использовать две модели для каждого объекта или две коллекции для каждого объекта. Если да, то, пожалуйста, объясните немного. Пожалуйста, направляйте меня, поскольку я новичок в backbone.js. Вот мой код.Salesforce: Как получить поля двух объектов «Учетная запись» и «Контакт» на странице visualforce с помощью Backbone.js?
