Rails image asset paths available in JavaScript

assets.coffee.erb

# Full code at https://gist.github.com/1406349/fa7c357b86790c183f3ef81ad6870b78bb2de343

window.assets = {
<%
Dir.glob(Rails.root.join("app/assets/images/**/*.*")).map do |path|
  img_name = path.gsub(Rails.root.join("app/assets/images/").to_s, "") %>
  "<%= img_name %>": "<%= asset_path(img_name) %>",
<% end %>
}

# Then all images are available as such: window.assets['my_image.jpg']

Doesn't work for me.

You are right. My mistake.
