You would "capture" that value in your controller when you handle the form submitted by the user, so in your #create or #update methods. Whatever that form field is named will be submitted in the params hash, with the value set to their choice.

If you are talking about capturing the setting before they submit the form, then you are into the realm of JavaScript, and in Rails this is usually handled in an unobtrusive JS handler. Read up on Ajax and Rails for more details about that.
