title: What's the right way to fill dynamic/static dropdown menus in rails?
body: <p>I've always wondered what do you guys do for filling out dropdown menus in rails, and not have the code splattered in the view. Do you guys make a pivot table? Do you make a class and add methods to return arrays? </p>
  
  <p>I always wonder how other people make them work, for example the other way I need to fill a combo box with all the countries I made a class called DropDownFiller, and added a method called fill_countries that would return an array with all the countries.</p>
  
  <p><strong>What are the best practices regarding this or how do you do it?</strong></p>
