Coffeescript Not Updating in Heroku - ruby-on-rails

Question

So, I've made a few changes to my web app that's hosted on Heroku and then I did my usual
git add .
git commit -m
git push
git push heroku
There were no errors during any of those commands... But then when I check the website, it seems like all the changes got pushed except for the changes in my Coffeescript file. And when I look at the source code of the webpage, I see the old JS code... It's like it skipped the changes in the coffeescript file.
There were no errors in the push and the coffee script file was in the list of files when I did the commit.
Here's what I've tried so far:
Add to my gemfile
gem 'therubyracer'
Add to Production.rb:
config.assets.compile = true
config.assets.initialize_on_precompile = true
Restarted Heroku server
Deleted my browser data...
None of this worked. Someone please help or point me in the right direction.
This is my Gemfile:
source 'https://rubygems.org'
ruby "2.2.1"
# Bundle edge Rails instead: gem 'rails', github: 'rails/rails'
gem 'rails', '4.2.4'
# Use SCSS for stylesheets
gem 'sass-rails', '~> 5.0'
gem 'bootstrap-sass', '~> 3.3.6'
gem 'sprockets-rails'
# Use Uglifier as compressor for JavaScript assets
gem 'uglifier', '>= 1.3.0'
# Use CoffeeScript for .coffee assets and views
gem 'coffee-rails', '~> 4.1.0'
gem 'jquery-rails'
gem 'turbolinks'
gem 'jbuilder', '~> 2.0'
gem 'sdoc', '~> 0.4.0', group: :doc
gem 'gon'
group :development, :test do
gem 'byebug'
end
group :development do
# Use sqlite3 as the database for Active Record
gem 'sqlite3'
gem 'web-console', '~> 2.0'
gem 'spring'
end
group :production do
gem 'pg', '0.17.1'
gem 'rails_12factor', '0.0.2'
gem 'puma', '2.11.1'
gem 'therubyracer'
end
And this is production.rb File:
Rails.application.configure do
config.cache_classes = true
config.eager_load = true
config.consider_all_requests_local = false
config.action_controller.perform_caching = true
config.serve_static_files = ENV['RAILS_SERVE_STATIC_FILES'].present?
config.assets.js_compressor = :uglifier
config.assets.compile = true
config.assets.initialize_on_precompile = true
config.assets.digest = true
config.log_level = :debug
config.i18n.fallbacks = true
config.active_support.deprecation = :notify
config.log_formatter = ::Logger::Formatter.new
config.active_record.dump_schema_after_migration = false
end
Thanks!

Answer 1

you likely have an error in your js or css that is keeping your assets from compiling. try compiling locally by running:
rake assets:precompile
then add and commit again before re-deploying.
