you model class is fine the way it is.
in app/controllers/UserController.rb you should have a method that has the same name as the template you want rails to automagically call. This method needs to pass the template a class variable (preceded by a '@') the template can have access to:
def list_users # same name as template @all_users = User.find(:all) # note @ before var name end # no need to invoke anything
then in app/views/users/list_users.rhtml you can access the collection of users via the class variable @all_users
example:
<ul> <% foreach user in @all_users %> <li><%= user.name </li> <% end %> </ul>
