asset pipeline not working on production, tried everythign - ruby-on-rails

Question

I have a rails 3.2 app on heroku. I have tried everything I can find to try to fix the fact that the javascripts are not loading in production mode. Everything works fine in dev though. Also, when deploying to heroku, the precompiling fails. However, when I look at the source code in prod, I can clearly see the javascripts file (/assets/application-32fdbd115c5d59c7be2876c103063600.js) loading and has content.
I have tried every setting I can think of and have read about. I am not quite sure what to do. Here's my setup currently in production.rb:
config.cache_classes = true
config.consider_all_requests_local = false
config.action_controller.perform_caching = true
config.serve_static_assets = false
config.assets.compress = false
config.assets.compile = true
config.assets.digest = true
config.i18n.fallbacks = true
config.active_support.deprecation = :notify
and in environment.rb:
# Load the rails application
require File.expand_path('../application', __FILE__)
# Initialize the rails application
App::Application.initialize!
application.rb:
require File.expand_path('../boot', __FILE__)
require "rails/all"
if defined?(Bundler)
# If you precompile assets before deploying to production, use this line
Bundler.require(*Rails.groups(:assets => %w(development test)))
# If you want your assets lazily compiled in production, use this line
# Bundler.require(:default, :assets, Rails.env)
end
module App
class Application < Rails::Application
config.encoding = "utf-8"
# Configure sensitive parameters which will be filtered from the log file.
config.filter_parameters += [:password]
# Enable escaping HTML in JSON.
config.active_support.escape_html_entities_in_json = true
config.active_record.whitelist_attributes = true
# Enable the asset pipeline
config.assets.enabled = true
# Version of your assets, change this if you want to expire all your assets
config.assets.version = '1.0'
and my gemfile:
gem 'rails', '3.2.6'
# Bundle edge Rails instead:
# gem 'rails', :git => 'git://github.com/rails/rails.git'
gem 'pg'
gem 'mysql2'
gem 'thin'
gem 'activerecord-postgresql-adapter'
gem 'devise'
gem 'paperclip', '~> 3.0'
gem 'haml'
gem 'activeadmin'
gem "meta_search", '>= 1.1.0.pre'
gem 'aws-sdk', '~> 1.3.4'
gem 'acts_as_list'
gem 'stripe'
gem 'sass-rails', '~> 3.2.3'
# Gems used only for assets and not required
# in production environments by default.
group :assets do
gem 'coffee-rails', '~> 3.2.1'
gem 'twitter-bootstrap-rails'
# See https://github.com/sstephenson/execjs#readme for more supported runtimes
# gem 'therubyracer', :platforms => :ruby
gem 'uglifier', '>= 1.0.3'
end
gem 'jquery-rails'
group :development do
gem 'debugger'
end
nothing I do seems to get it to work on production mode on my local machine or on heroku. however, it works just fine in development.

Answer 1

I finally figured out how to fix this, although I don't know how good of a fix it is. Basically, the problem was that the compression of the .js files into application.js was causing issues. In production.rb I put this:
config.serve_static_assets = false
# Compress JavaScripts and CSS
config.assets.compress = false
# Don't fallback to assets pipeline if a precompiled asset is missed
config.assets.compile = true
# Generate digests for assets URLs
config.assets.digest = true
config.assets.debug = true
this fixed the issue. however, now instead of application.js, it lists all the asset files. i'm not sure if there are any long-term issues with this.

On your production box have you tried: RAILS_ENV rake assets:precompile
