ruby-on-rails - 俄罗斯娃娃在 rails 上缓存

我听DHH和其他伟大的37Signal家伙谈论了很多关于俄罗斯娃娃缓存的事情，我理解它的概念，但是我不知道如何将它应用到我的代码中。
你将如何应用它？

如何将gem应用到包含大量if语句的代码中？

    <% if signed_in? %>
      <div class="timeline">
        <%= link_to image_tag(current_user.avatar), designer_path(current_user), :class => "avatar topimg" %>
        <%= content_tag(:span, "your profile", :class => "description") %>
        <%= link_to "", new_design_path, :class => "upload icon-upload" %>
        <%= content_tag(:span, "upload a new design", :class => "description") %>
        <%= link_to "", designer_path(current_user)+"/favorites", :class => "upload icon-star" unless current_user.followees_by_type("design").blank? %>
        <%= content_tag(:span, "designs you've favorited", :class => "description") unless current_user.followees_by_type("design").blank? %>
        <%= content_tag(:span, current_user.current_invites, :class => "invites_count") unless current_user.current_invites <= 0 || current_user.full_member == false %>
        <%= link_to "", "#", :class => "invite icon-plus "+("blue" unless current_user.current_invites == 0).to_s unless current_user.current_invites < 0 || current_user.full_member == false  %>
        <%= content_tag(:span, "invite a friend ("+current_user.current_invites.to_s+" invites left)", :class => "description") unless current_user.current_invites < 0  %>
        <%= content_tag(:span, activity, :class => "activity_count") unless activity == 0 %>
        <%= link_to "", designer_path(current_user)+"/statistics", :class => "upload icon-activity "+("blue" unless activity == 0).to_s unless activity == 0 %>
        <%= content_tag(:span, ("your activity ("+pluralize(activity, 'new thing')+")"), :class => "description") unless activity == 0%>
      </div>
    <% else %>
      <%= link_to raw('<i class="icon-twitter icon-font"></i><span>login with twitter</span>'), "/auth/twitter", :class => "btn btn-twitter grey-tweet" %>
    <% end %>

查看他们发布的the Gem，它有一些像样的文档。
