Как получить URL-адрес в нижнем формате

Я могу сгенерировать URL-адрес и связанную с ним веб-страницу с помощью rails generate controller static_pages about. Таким образом, URL будет что-то вроде этого www.bla.com/static_pages/about'. Now I want to generate this url bla.com/help` без использования генерации,Как получить URL-адрес в нижнем формате

Я добавил маршрут в routes.rb как этот get 'help'

Затем я добавил действие в application_controller.rb как это
def hello render text: "Hello" end

Затем при запуске сервера, я получаю следующее сообщение об ошибке

Отсутствует: ключ контроллера по определению маршрутов, пожалуйста, проверьте свои маршруты . (ArgumentError)

Как говорится об ошибках, необходимо указать controller и action соответствия к route. Нижеследующее должно работать.

get "help", to: 'static_pages#about', as: 'help' 
        ^^^^^^ ^^^^ 
       controller action

Кроме того, я предлагаю вам следовать этому Guides для ясного понимания того, как определить маршруты.

У меня нет staticpages/help. Я не хочу этого, я хочу, чтобы он был bla.com/help – gates

@gates Маршрут будет таким, каким вы хотели :) – Pavan

Я обновил свой вопрос. Можете ли вы проверить один раз – gates
