Я только начал изучать ruby на рельсах и, просматривая руководство ссылка , я не могу изменить отображение страницы на шаге 4.3
мой файл rout.rb выглядит точно так, как рекомендовано в руководстве, имея только две линии между ничьей и ее концом:
get 'welcome/index'
root 'welcome#index'
, а мой индекс. html .erb файл выглядит так:
<h1>Hello, Rails!</h1>
еще когда я загрузить страницу localhost:3000, выдает ошибку
В индексе WelcomeController # отсутствует шаблон для форматов запроса: текст / html
, хотя файл index.html.erb действителен. какие-либо предложения, в чем может быть дело?
РЕДАКТИРОВАТЬ: журнал сервера выглядит следующим образом:
Started GET "/welcome/index" for ::1 at 2020-02-12 15:19:39 -0500 (5.7ms) SELECT sqlite_version(*) Processing by WelcomeController#index as HTML Completed 406 Not Acceptable in 28ms (ActiveRecord: 0.0ms | Allocations: 1989)

Я также пытался продолжать следовать руководству к шагу 5.1, и хотя все ошибки появляются как говорится в руководстве, «решение» в конце этого шага по-прежнему вызывает ошибку в формате шаблона.
