Ruby on rails link_to global class?

Question

Is there a way to add class by default in a link_to helper? This global setting should prevent me manually adding the :class option everytime.

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" %>
