Rails current url helper

Question

Apologies for such a simple question, but I couldn't been able to solve it myself after hours since my RoR knowledge is basically nonexistent. In the Rails application I'm working with, has been used a navigation helper to highlight active menu:

  def nav_link(link_text, link_path, ico_path)
    class_name = current_page?(link_path) ? 'active' : nil

    content_tag :li do
      link_to(link_path, class: class_name) do
        image_tag("icons/#{ico_path}.svg") + content_tag(:span, link_text)
      end
    end
  end

The circumstances have changed and current_page? is no longer a viable option, since routing now handled on the front-end. Is there a way to achieve the same functionality by retrieving, for instance, current url and check it against link_path?. I've tried a lot of things with different helpers like request.original_url, but to no avail.

Answer 1

request.original_url should work according to the documentation.

Returns the original request URL as a string

http://apidock.com/rails/ActionDispatch/Request/original_url

You could also try string concatenation with different variables.

request.host + request.full_path

If that doesn't work either, you could try

url_for(:only_path => false);
