Changing underscores to hyphens in URLs Ruby on Rails

Question

I need to change underscores to hyphens for SEO of our to-do checklist page in Ruby on Rails project. The relevant line in routes.rb file is below:

get 'to_do' => 'current_to_do_items#landing', :as => :to_do

I tried to change it to:

get 'to-do' => 'current_to_do_items#landing', :as => :to-do

but in this part "as => :to-do" do is detected as a key word, could you please advise how should I name it?

Answer 1

:as option generates urls helpers, even if you change it to as: "to-do" your helpers will not change: to_do_path and to_do_url. All of these generate the same route and helpers:

# technically, you don't need :as option here, because it's the same as path
get "to-do", to: "current_to_do_items#landing"

get "to-do", to: "current_to_do_items#landing", as: :to_do
get "to-do", to: "current_to_do_items#landing", as: "to-do"

You can quote symbols if you have characters other than letters and underscores:

{ "to-do": :"to do!" }
