rake assets:precompile stuck - ruby-on-rails

Question

couple of days ago i noticed that jquery calendar is not working on my deployment site(heroku). on digging out the problem i noticed that source of site on my dev server has some 100 script tags related to bootstrap(i am using twitter bootstrap css) but on prod server. i have 4 script tags. on searching i found that i should run rake assets:precompile on my rails console fo asset pipeline. but while running it is taking terribly long time, last time it took 6 hours and i had to abort it.
referring to many sites and post, i found that i should change config.serve_static_assetsto true and config.assets.compile to true. but problem is still there. i also tried to remove jquery-rails/jquery-ui-rails from gembut problem is still there.
here is my config/environmnets/production.rb
ProductRecall::Application.configure do
# Settings specified here will take precedence over those in config/application.rb
# Code is not reloaded between requests
config.cache_classes = true
# Full error reports are disabled and caching is turned on
config.consider_all_requests_local = false
config.action_controller.perform_caching = true
# Disable Rails's static asset server (Apache or nginx will already do this)
config.serve_static_assets = true
# Compress JavaScripts and CSS
config.assets.compress = true
# 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
# Specifies the header that your server uses for sending files
# config.action_dispatch.x_sendfile_header = "X-Sendfile" # for apache
config.action_dispatch.x_sendfile_header = 'X-Accel-Redirect' # for nginx
# Force all access to the app over SSL, use Strict-Transport-Security, and use secure cookies.
config.force_ssl = true
# Enable locale fallbacks for I18n (makes lookups for any locale fall back to
# the I18n.default_locale when a translation can not be found)
config.i18n.fallbacks = true
# Send deprecation notices to registered listeners
config.active_support.deprecation = :notify
# Log the query plan for queries taking more than this (works
# with SQLite, MySQL, and PostgreSQL)
# config.active_record.auto_explain_threshold_in_seconds = 0.5
config.action_controller.perform_caching = false
end
my config/application.rb looks like this
require File.expand_path('../boot', __FILE__)
# Pick the frameworks you want:
require "active_record/railtie"
require "action_controller/railtie"
require "action_mailer/railtie"
require "active_resource/railtie"
require "sprockets/railtie"
# require "rails/test_unit/railtie"
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 ProductRecall
class Application < Rails::Application
# Configure the default encoding used in templates for Ruby 1.9.
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
# Enforce whitelist mode for mass assignment.
# This will create an empty whitelist of attributes available for mass-assignment for all models
# in your app. As such, your models will need to explicitly whitelist or blacklist accessible
# parameters by using an attr_accessible or attr_protected declaration.
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'
config.action_mailer.default_url_options = { host: 'localhost:3000' }
end
end
here is my Gem file:
source 'https://rubygems.org'
gem 'rails', '3.2.13'
gem 'bootstrap-sass', '2.1'
gem 'bcrypt-ruby', '3.0.1'
gem 'therubyracer', :platforms => :ruby, :platforms => :ruby
gem 'faker', '1.0.1'
gem 'will_paginate', '3.0.3'
gem 'bootstrap-will_paginate', '0.0.6'

gem "galetahub-simple_captcha", :require => "simple_captcha"
gem 'rufus-scheduler'
group :development, :test do
gem 'sqlite3', '1.3.5'
gem 'rspec-rails', '2.11.0'
end
group :development do
gem 'annotate', '2.5.0'
end
group :assets do
gem 'sass-rails', '3.2.5'
gem 'coffee-rails', '3.2.2'
gem 'uglifier', '1.2.3'
end
gem 'jquery-rails', '2.0.2'
group :test do
gem 'capybara', '1.1.2'
gem 'factory_girl_rails', '4.1.0'
gem 'cucumber-rails', '1.2.1', :require => false
gem 'database_cleaner', '0.7.0'
end
#gem 'jquery-ui-rails'
group :production do
gem 'pg', '0.12.2'
end
plz let me know what is wrong here. as i am terribly stuck with no clue since 2 days

Answer 1

I had also faced the same problem. Actually gem gets conflict. Here 'rufus-scheduler' gem is the culprit. Try to remove the gem and deploy.
Next you can try this
task :precompile, :roles => :web, :except => { :no_release => true } do
run_locally("rm -rf public/assets/*")
run_locally("bundle exec rake assets:precompile")
servers = find_servers_for_task(current_task)
port_option = port ? " -e 'ssh -p #{port}' " : ''
servers.each do |server|
run_locally("rsync --recursive --times --rsh=ssh --compress --
human-readable #{port_option} --progress public/assets #{user} ##{server}: {shared_path}")
end
end
