Rails: Javascript not getting to heroku

Question

My javascript is not making it to my heroku app even though my application.html.haml file has: = javascript_include_tag "application". I threw in an alert to check if any js is making it there but no cigar. I also checked in firebug and the javascript isn't being sent to the browser what-so-ever. Any ideas?

application.js

//= require jquery
//= require jquery_ujs
//= require_tree .
//= require jquery_nested_form
//= require jquery-fileupload
//= require autoNumeric
//= require lightbox

alert('test?');

Production.rb

MyMyApp::Application.configure do
  config.force_ssl = true
  config.cache_classes = true
  config.consider_all_requests_local       = false
  config.action_controller.perform_caching = true
  config.serve_static_assets = true (I tried false)
  config.assets.compress = true
  config.assets.compile = true
  config.assets.digest = true
  config.i18n.fallbacks = true
  config.active_support.deprecation = :notify
end

ruby '2.0.0'

gem 'rails', '3.2.13'

Does your application.js have the alert code inside or not if you do View Source on Heroku? — Richard Peck

if you want the alert to appear you have to add //= require_self — Manuel van Rijn

There are many problems with asset pipeline and heroku. Check this linke

https://devcenter.heroku.com/articles/rails-asset-pipeline

Or simply put into config/application.rb line:

config.assets.initialize_on_precompile = false

This should solve your problems cheers.

can you post your javascript include tag from application layout ? and config/environments/production.rb files

2 things:

-> Try to call when document is ready

$(document).ready(function() {
    alert('hello');
});

-> Try to precompile assets before pushing to Heroku:

in your production.rb:

config.serve_static_assets = true
config.assets.compile = true

in your cmd:

> rake assets:precompile
> git push heroku master

it is alert it will work anyway. I think the problem is that heroku is not serving his assets.
