ruby-on-rails - 在 haml View 中重构条件

Question

除了可访问性标准不鼓励使用这一事实指向当前页面的链接，我应该怎么做重构以下 View 代码？

#navigation
  %ul.tabbed
    - if current_page?(new_profile_path)
      %li{:class => "current_page_item"}
        = link_to t("new_profile"), new_profile_path
    - else
      %li
        = link_to t("new_profile"), new_profile_path

    - if current_page?(profiles_path)
      %li{:class => "current_page_item"}
        = link_to t("profiles"), profiles_path
    - else
      %li
        = link_to t("profiles"), profiles_path
    ...

谢谢。

# helpers
def current_page_class(page)
  return :class => "current_page_item" if current_page?(page)
  return {}
end

-# Haml
#navigation
  %ul.tabbed
    %li{current_page_class(new_profile_path)}
      = link_to t("new_profile"), new_profile_path
    %li{current_page_class(profiles_path)}
      = link_to t("profiles"), profiles_path
    ...
