and I want to call this rails

Answer 1

Make an AJAX call, set up a route, respond with a controller action and call your method.

# whatever.js
$("p.exclamation, div#notification_box").on("mouseover", function() {
  $.ajax("/users/render_read")
});

# routes.rb
resources :users do
  get :render_read, on: :collection 
  # or you may prefer to call this route on: :member
end

# users_controller.rb
def render_read
  @current_user.render_read
  # I made this part up, do whatever necessary to find the needed user here
end

PS: This code is for Rails 3.x and Ruby 1.9.x
