ruby-on-rails - 在 Rails 中重定向动态路由

Question

如何重定向

get '/directory/:alphabet' => redirect('/directory/:alphabet/1') , :constraints => { :alphabet => /[A-Za-z#]/}

这会引发有关字母表的错误。我如何使用我获得的值(value)？

Answer 1

请参阅 http://guides.rubyonrails.org/routing.html#redirection 下的“动态分割”

使用 %{alphabet} 从源读取值

get '/directory/:alphabet' => redirect('/directory/%{alphabet}/1') , :constraints => { :alphabet => /[A-Za-z#]/}
