Rails4: How to serve gem specific javascript files?

Question

I copied a working rails app into a different directory and renamed it using the rename Gem.

Most of the rails functionality works correct, but I am not able to serve assets bundled with gems specifically js files from bootstrap-slider-rails

I have compared my application.rb , Gemfile and application.js and they are the same in both apps.

I have tried uninstalling and installing the gem again

Simple comparison among the apps is not resolving issue.

Here are the files I have verified are same in both apps:

1. Gemfile
2. application.rb
3. application.html.haml
4. application.js

Any suggestions how I should debug this ?

Thanks!

Here is how some relevant files look like:

application.js

application.rb

require File.expand_path('../boot', __FILE__)

# Pick the frameworks you want:
require "active_record/railtie"
require "action_controller/railtie"
require "action_mailer/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

# Rails4
Bundler.require(:default, Rails.env)

module Smoothlyhired
  class Application < Rails::Application

    # don't generate RSpec tests for views and helpers
    config.generators do |g|

      g.view_specs false

    end


    config.autoload_paths += %W(#{config.root}/lib)



    config.encoding = "utf-8"

    # Configure sensitive parameters which will be filtered from the log file.
    config.filter_parameters += [:password, :password_confirmation]


    config.active_record.schema_format = :sql



    # 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'

    #Prevent initializing the application and connecting to db on bootup as required by heroku
    #https://devcenter.heroku.com/articles/rails-asset-pipeline
    # Not required on rails4 anymore
    #config.assets.initialize_on_precompile = false

    #config.action_view.javascript_expansions[:defaults] = %w(jquery.min jquery_ujs)

Try deleting your gemfile.lock and running bundle install again.

Also refer to this SO post on copying and deploying rails apps. If you didn't, you should delete the .git file and run git init.

I'm not 100% sure this will fix your problem, but my suspicion is that you have gem issue.
