Ruby on Rails link_to全局类？

Question

有没有一种方法可以默认在link_to帮助器中添加类？ 这个全局设置应该阻止我每次手动添加：class选项。

Answer 1

application_helper.rb

def nav_link(text, controller, action="index", class)
    link_to_unless_current text, :id => nil,
                                 :action => action,
                             :controller => controller,
                                     :class => class
end

Views.html.erb

<%= nav_link "text", "controller", "action", "MYCLASS" %>
