title: Best way to handle view and helper-only constants in Rails
body: <p>I have a constant that is only used in views, but it's used in different ways in different places.  It's an array of option names, and is used for select boxes, but I also use this in other views to see if strings are found in this array, and respond accordingly.</p>
  
  <p>What's the best way to handle this to keep DRY?</p>
  
  <p>I initially created a constant in a helper, but that doesn't seem to be accessible in the views.</p>
  
  <p>I've since switched to creating a method in a helper, that does nothing except return the constant.  However, this really seems to be against the spirit of Rails, since now essentially I'm using a lower-cased constant.</p>
  
  <p>I could of course stick it in a model, but it's really got nothing to do with any of the models.</p>
