Answer 1

In the interest of not having to repeat your self too much by having to check current_page inside the link_to method all the time, here's a custom helper that you can use (put this in app/views/helpers/application_helpers.rb

def link_to_active_class(name, active_class_names, options = {}, html_options = {}, &block)
  html_options[:class] = html_options[:class].to_s + active_class_names if current_page?(options.to_s)
  link_to name, options, html_options, &block
end

Example usage:

 <%= link_to_active_class('Dashboard', 'bright_blue', dashboard_path, class: 'link_decor') 

if you are on http://example.com/dashboard, then it should return:

 Dashboard
