Я работаю со сторонним приложением и на данный момент для загрузки изображения с активным хранилищем рельсов у меня есть только доступ к встроенным данным (например: data: image / png; base64, iVBORw0KG ....) Какхранить тогда с активным хранилищем?Или конвертировать его в BLOB-объект?
avatar.attach работает только с BLOB-файлом или загруженным файлом из запроса / формы
