备用引导程序表行着色不起作用

Question

我正在尝试根据单个属性为rails表中的某些行着色。我只是说明了这一点，所以人们不会感到困惑，以为我正试图改变我表中的颜色。那不是目标。事情是，它在20分钟前工作，我的haml文件中的%tr.error和%tr.warning正确地将行着色（使用引导程序），但现在它们什么也没做。我在这里看到有关排序表如何搞乱着色的问题。我正在使用think-sphinx作为我的应用程序的搜索引擎。这可能是问题吗？如果是这样，有没有办法解决这个问题，而不是让我的手在Javascript中太脏？ （这不是我的强项）

                %td
                  = m.rec_form
                %td
                  = m.loanee
                %td
                  = link_to 'Check out', edit_movie_path(m), {:class => "btn"}    
      = will_paginate

我试图添加一部分以减轻重复次数，这就是当事情开始破碎时。
