ActionView::Template::Error (audiojs/audio.min.js isn't precompiled)

how to solve the problem?

Answer 1

The problem is in your main page javascript. You're trying to load a track, but the elements you're looking for don't exist so you're getting the undefined error.

var audio = a[0];
first = $('ol a').attr('data-src');

// Add this code to layouts/application.html.erb
// First is coming back undefined on your root route.
if (first == undefined)
  console.log("First is undefined! Will cause error in audio track");

$('ol li').first().addClass('playing');
audio.load(first);

Whereas, you're setting data-src="<%= show.preview %>" in releases/show.html.erb (and index.html.erb ) and the code works without issue there.

Your options are to detect if there are no order list items and not try to automatically play an audio track, or add audio tracks to your main page.
