Routes with Dash `-` Instead of Underscore `_` in Ruby on Rails

Question

I want my urls to use dash - instead of underscore _ as word separators. For example controller/my-action instead of controller/my_action.

I'm surprised about two things:

1. Google et al. continue to distinguish them.
2. That Ruby on Rails doesn't have a simple, global configuration parameter to map - to _ in the routing. Or does it?

The best solution I've is to use :as or a named route.

My idea is to modify the Rails routing to check for that global config and change - to _ before dispatching to a controller action.

Is there a better way?

Answer 1

With Rails 3 and later you can do like this:

resources :user_bundles, :path => '/user-bundles'

Another option is to modify Rails, via an initializer. I don't recommend this though, since it may break in future versions (edit: doesn't work in Rails 5).

Using :path as shown above is better.

module ActionDispatch
  module Routing
    class Mapper
      module Resources
        class Resource
          def path
            @path.dasherize
          end
        end
      end
    end
  end
end
