title: Rails Model without a table
body: <p>I want to create a select list for lets say colors, but dont want to create a table for the colors. I have seen it anywhere, but can't find it on google. </p>
  
  <p>My question is: How can I put the colors in a model without a database table?</p>
  
  <p>Or is there a better rails way for doing that?</p>
  
  <p>I have seen someone putting an array or a hash directly in the model, but now I couldn't find it.</p>
