Rails only execute javascript if current_user logged_in

Question

I have a script that executes (shows a modal) at 35 minutes (from inactivity) alerting the user they are about to be logged out. If they click a button in that modal they can remain logged in or another button to log out. The problem is the script is running whether a user is logged in or not. How can I limit the script to only load and be run if there is a current_user.
I tried adding erb to my coffee script file and just using an if logged_in? block, but I get errors when trying to include the helper in that file. And, this seems like an awful way to do it.

What's the error you're getting? Try changing the file to file_name.coffee.erb that will let you execute ruby in your coffee file. — johnkoht

Also, you can try adding a class to your body tag, i.e. user-logged-in, which you can add in your layouts template. And then make your javascript dependent on whether body.user-logged-in is present. It's not pretty but it would work. — johnkoht

In application.html.erb:

<%= javascript_include_tag "application" unless current_user.nil?  %>
