Add an 'active' class to all active links in rails?

Question

Basically, I have a lot of code that looks like this:

link_to t(\'.profile\'), business_path(@business), class: \'#{\'active\' if current_page? business_path(@bu

Here's the helper I use. I add an optional "match_text" parameter for added flexibility (for instance, if I want to mark a link as active when the actual request path is a child page of the link's destination.)

def link_to_active(text, destination, options = {})
  match_text = options.delete(:match_text)

  classes = options[:class].present? ? options[:class].split(" ") : []
  classes << "active" if request.fullpath.downcase == destination.downcase || (match_text && request.fullpath.downcase.include?(match_text.downcase))

  options = options.except(:class)
  options.merge!(:class => classes.join(" ")) unless classes.empty?

  link_to(text, destination, options)
end
