DRY up Rails Navigation Code In my Rails 4 app i used to have every view contain a content_for :nav tag which included all of the links for the nav bar in my layout. This was getting annoying because if i wanted to add a button i would have to go through every view and add that link. I decide to make a partial view in layouts/_nav.haml which contains:

= link_to 'Home', root_path, :class =&gt; "btn #{active_page(root_path)}"
= link_to 'Sign in', sign_in_path, :class =&gt; "btn #{active_page(sign_in_path)}"
= link_to 'Account', account_path, :class =&gt; "btn #{active_page(account_path)}"


and then in my application_helper.rb i added:

def active_page(path)
  'active' if current_page?(path)
end


I know this isn't the best approach, is there any way to DRY up this solution or make it better. Im using bootstrap and i tried the simple-navigation gem but it wasn't that useful in my situation.
You could create another helper to create your navigation links:

def navigation_link_to(text, path)
  link_to text, path, class: "btn #{active_page(path)}"
end 


Then in your view:

= navigation_link_to 'Home', root_path
= navigation_link_to 'Sign in', sign_in_path
= navigation_link_to 'Account', account_path
