Topic: Refactoring to REST with ajax

Hello
I've a view with a select_tag wich contains articles, and the appropriate article is displayed onchange (when clicked). how can I refactor this to CRUD methods :

<%= select_tag 'articles', options_for_select(@articles), 
           :onChange => remote_function(:url => display_article,
                                        :with => "'article='+this.value") %>

Should I rename display this view to new? (or index????) and display_article to show???
