Answer 1

in views/layouts/application.html.erb write in head

<script>
window.user_id = <%= user_signed_in? && current_user.id %>;
</script>

and in your coffeescript
url = "/users/#{window.user_id}/events.json"

1. Move this script to the view template (html, haml ...) (so that the script does not go to the pipeline once), and insert <%= @user.id %> directly in the code
2. Specify the user ID in some any date attribute:

<div id='calendar'>
 <div class='event' data-user-id='<%= user.id %>'>
 </div>
</div>
