ruby-on-rails - rails : Elegant way to handle navigation?

Question

现在我有一个看起来像这样的导航部分(x10 按钮)...

<% if current_controller == "territories" %>
    <li><%= link_to "Territories", {:controller => 'territories'}, :class => 'active'  %></li>
<% else %>
    <li><%= link_to "Territories", {:controller => 'territories'}  %></li>
<% end %>
<% if current_controller == "contacts"  %>
    <li><%= link_to "Contacts", {:controller => 'Contacts'}, :class => 'active'  %></li>
<% else %>
    <li><%= link_to "Contacts", {:controller => 'Contacts'}  %></li>
<% end %>

有没有更优雅/干燥的解决方案来做到这一点？

Answer 1

与查克所说的类似:

<% TARGETS.each do |target| %>
  <li>
    <%= link_to target.humanize, 
      { :controller => target }, 
      class => ('active' if current_controller == target)) %>
  </li>
<% end %>
