Rails @users.each 这个方法里，可以调用一个计数器？

我就实现一个排行列表，每个 li 都根据每个 user 的排名使用不同的 class

<% @users.each do |user| %>
   <li class="numX">......
<% end %>

x = 1,2,3,4,5......

怎样实现？自己加个变量？还是本来 each 有提供？查手册，查不到！

好像还有个 cycle helper 可以用，自己日一下

<%= render :partial => 'user', :collection => @users %> 如果是 render，就可以在 partial 里用 user_counter

#4 楼 @kimigao1986 可以直接= render @users
