В rails 4.0.2 я пытаюсь реализовать функцию событий календаря, но она ничего не отображает. Я использовал драгоценный камень fullcalendar, на который ссылаются https://github.com/vinsol/fullcalendar-rails-engine , но я получаю сообщение об ошибке, как показано ниже,

 Processing by Rails::WelcomeController#index as HTML
