Я поддерживаю приложение rails 2.1, которое имеет неудачный выбор для имен столбцов.Например, событие имеет дату начала и окончания.Вместо использования start_at и end_at в оригинальном дизайне используются start и end.Конечно это приводит к
def end
read_attribute(:end) || 1.hour.from_now
end
Я удивлен, что это даже анализирует.Это законный рубин?Реальная проблема заключается в том, что при запуске задания backgroundrb для отправки электронных писем с напоминаниями erb взрывается с «слишком большим уровнем стека».Шаблон имеет вид
<%= [@event.name, @event.when_pretty, @event.location, @event.association,
@event.notes].reject(&:blank?) * "\n" %>
Если я доставляю_reminder в консоли, ошибки не возникает, но при вызове delivery_reminder во время фонового задания возникает ошибка.
Вопрос.end метод, или ошибка стека вызвана чем-то другим?
В строке # 1 файла foo / mailer / Remder.rhtml
1: <%= [@event.name, @event.when_pretty, @event.location, @event.association, @event.notes].reject(&:blank?) * "\n" %>
