I need help to sort out problems of asset pipeline with my app. Can anyone have look at what I am missing? Thanks in advance.
I am using the following rails 3.2.13, ruby 1.9.3 (for development) and ruby 2.0.0 (for production on heroku). ( I am using a different version of ruby on production as a gem called bybosa could not be installed with the development version of ruby… I am not sure if this is the source of the problem. Probably not…). I have precompile the assets locally running: bundle exec rake assets:precompile RAILS_ENV=production. The assets get precompiled well and placed in public/assets/ directory. However, this process runs with an error : "can't dump anonymous class" errors. This seems to be associated with sass and sprockets… but the compilation get completed with files placed in the public/assets directory. The original images, and the same image names with long hash extensions. I commit everything to git and deploy from git to heroku. Heroku does not run assets compilation as there is a manifest file in the public/assets directory. The application gets deployed well, but the images are not served properly. CSS and JS are served. The styling of the layout is as expected at least. So no problem with CSS and JS (that I can note). *The website as it now appears * *http://www.cdh-uk.org/ <http://www.cdh-uk.org/>* *The github app: * *https://github.com/mazembo/cdhuk <https://github.com/mazembo/cdhuk>* Only two images are served. Other 10 images are not served. Heroku logs shows that the error 404 not found for those images. And the path for those images are /assets/image_name. The two images that are served have these paths /assets/image_name + hash(combination of letters and numbers produced by the asset pipeline during the precompile operation). When you inspect elements on the webpage, only those two images that get displayed have the long hash after the image name. All othe images do not have the hash… I wonder why the webserver is not able to find the other images. Why is the webserver not pointing to the images as precompile by the asset pipeline with the long hash extension? In the development environment all images are well displayed. Here, images are referenced by their simple name (without the asset pipeline extensions). *My gemfile * source 'http://rubygems.org' ruby "2.0.0" gem 'rails'*, *'3.2.13' # Bundle edge Rails instead: # gem 'rails', :git => 'git://github.com/rails/rails.git' group *:development**, **:test**, **:production **do* # gem 'sqlite3' gem 'pg' *end* # Gems used only for assets and not required # in production environments by default. #group :assets do # gem 'sass-rails', '~> 3.2.3' # 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 # Use SCSS for stylesheets gem 'bootstrap-sass'*, *'3.1.1.0' gem 'sass-rails'*, *'>= 3.2' gem 'jquery-rails' gem 'turbolinks' gem 'rails_12factor'*, *group: *:production* # To use ActiveModel has_secure_password # gem 'bcrypt-ruby', '~> 3.0.0' # To use Jbuilder templates for JSON # gem 'jbuilder' # Use unicorn as the app server # gem 'unicorn' # Deploy with Capistrano # gem 'capistrano' # To use debugger # gem 'debugger' # Refinery CMS gem 'refinerycms'*, *'~> 2.1.0' # Optionally, specify additional Refinery CMS Extensions here: gem 'refinerycms-acts-as-indexed'*, *'~> 1.0.0' gem 'refinerycms-blog'*, *'~> 2.1.0' gem 'refinerycms-inquiries'*, *'~> 2.1.0' gem 'refinerycms-search'*, *'~> 2.1.0' gem 'refinerycms-page-images'*, *'~> 2.1.0' gem "refinerycms-news"*, *'~> 2.1.0' #gem 'refinerycms-portfolio', :git => 'git:// github.com/refinery/refinerycms-portfolio.git', :branch => '2-0-stable' gem 'refinerycms-videojs' #gem 'refinerycms-memberships', '2.0' #gem 'refinerycms-calendar', '~>2.0.0' #gem 'refinerycms-bootstrap', :github => 'fernandoaleman/refinerycms-bootstrap', :branch => 'master' group *:development **do* gem 'jazz_hands' *end* *My config/application.rb file * 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 *Renaissance2 *class *Application < Rails*::*Application # Settings in config/environments/* take precedence over those specified here. # Application configuration should go into files in config/initializers # -- all .rb files in that directory are automatically loaded. # Custom directories with classes and modules you want to be autoloadable. # config.autoload_paths += %W(#{config.root}/extras) # Only load the plugins named here, in the order given (default is alphabetical). # :all can be used as a placeholder for all plugins not explicitly named. # config.plugins = [ :exception_notification, :ssl_requirement, :all ] # Activate observers that should always be running. # config.active_record.observers = :cacher, :garbage_collector, :forum_observer # Set Time.zone default to the specified zone and make Active Record auto-convert to this zone. # Run "rake -D time" for a list of tasks for finding time zone names.
