rack-pjax working in development but not production - ruby-on-rails

Question

So I recently installed rack-pjax in my app to make it and so some sidebars wouldn't reload on navigation, and I got it working in development, but when I pushed it up to heroku, for some reason, it didn't work.
If I navigate to, say, "/music", it reloads the entire page, with the URL going from "/music" to "/music#" and back to "/music".
Edit {
In the heroku logs, you can see it sends the GET request twice, which explains the discrepancy in the URL. If the second GET request didn't happen, it should work.
}
Here's my log of me doing it in development:

Answer 1

Before you call pjax, try adding this to your JavaScript:
$(document).on('pjax:timeout', function() {
return false;
});
This will disable the timeout. I had this exact same problem and the issue was that my app was too slow, and was taking too long to load, and pjax would cancel the request and send the browser on. You can of course increase the timeout but I thought this was nicer.
