用ruby on rails写的一个博客程序,还不错..ruby on rails的确是个好框架

  <h4><%= _("Currently this article is listed in following categories")%>:</h4>
  <% for category in @article.categories %>
    <%= link_to_remote "- #{category.name}", :url => { :action => "category_remove", :id => @article.id, :category_id => category.id }, :update => 'categories' %><br/>
  <% end %>

  <% for category in @categories - @article.categories %>
    <%= link_to_remote "+ #{category.name}", :url => { :action => "category_add", :id => @article.id, :category_id => category.id }, :update => 'categories' %><br/>
