Не могу понять конец этих методов

Я использую Ruby 1.8.7 и прохожу 8-ю главу учебника по рельсам. Я получаю синтаксическую ошибку неожиданного $end, ожидая kEND. Я знаю, что это означает, что мне где-то не хватает конца, но в обоих файлах я не могу понять это. Вот оба моих файла. Спасибо заранее за любую помощь
