Best approach to use dashed slugs separated by a dash:

get ':foo-:bar', to: 'foo#bar' 

foo could be my-value and bar could be other-value

My url is then my-value-other-value

What is the best approach to do this except changing the param separator to something else?

I do know all value for foo and all values for bar as these are stored in corresponding models. I’m afraid using this method will be poor in performances.
