Images not loading on Linode VPS - ruby-on-rails

I deployed my new rails 4 application to linode.
My js/css are loaded properly but the images are not loading.
Here are my setting in production.rb.
# Compress JavaScripts and CSS.
config.assets.js_compressor = :uglifier
# config.assets.css_compressor = :sass
# Do not fallback to assets pipeline if a precompiled asset is missed.
config.assets.compile = true
# Generate digests for assets URLs.
config.assets.digest = true
# Version of your assets, change this if you want to expire all your assets.
config.assets.version = '1.0'
config.serve_static_assets = 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
EDIT
So i checked my shared/assets/images
It has the image like twitter-7ea9292a334406402a4f2e823622fe49.png
But when I inspect my html it shows
<img src="assets/twitter.png">

Rails app not loading assets on elastic beanstalk aws

For context, I essentially followed this guide to get my rails app set up: https://medium.com/#jatescher/how-to-set-up-a-rails-4-2-app-on-aws-with-elastic-beanstalk-and-postgresql-3f9f29c046e2
My app is now running on AWS:
http://ems-heroes-dev.elasticbeanstalk.com/
64bit Amazon Linux 2015.03 v2.0.1 running Ruby 2.2 (Puma)
However, I can't get any of my assets to load.
Here is my config/environments/production.rb:
EmsHeroes::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_assets = true
# Compress JavaScripts and CSS.
config.assets.js_compressor = :uglifier
config.assets.compress = true
config.assets.compile = true
# Bower asset paths
root.join('vendor', 'assets', 'components').to_s.tap do |bower_path|
config.sass.load_paths << bower_path
config.assets.paths << bower_path
end
# Precompile Bootstrap fonts
config.assets.precompile << %r(bootstrap-sass/assets/fonts/bootstrap/[\w-]+\.(?:eot|svg|ttf|woff2?)$)
# Minimum Sass number precision required by bootstrap-sass
::Sass::Script::Value::Number.precision = [8, ::Sass::Script::Value::Number.precision].max
config.less.paths << "#{Rails.root}/lib/less/protractor/stylesheets"
config.less.compress = true
# Generate digests for assets URLs.
config.assets.digest = true
config.assets.enabled = true
# Version of your assets, change this if you want to expire all your assets.
config.assets.version = '1.0'
# 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 = false
config.log_level = :info
config.i18n.fallbacks = true
config.active_support.deprecation = :notify
config.log_formatter = ::Logger::Formatter.new
end
My assets are loading fine via heroku though. (However, I dont plan on using heroku any more)
EDIT
It looks like its an issue with rake assets:precompile providing the wrong file names. Ex: My compiled css file is: "public/assets/application-79dc234c01a4f604b52fc53ff49ac89d.css" but Im getting a 404 looking for "application.css". Renaming the file to "public/assets/application.css" will load it properly.
Any idea why this would be the case and how I can get it to precompile properly?
This string after file name is called "digest", it's used to notify browser when file content changes. You need to use view helpers (asset_path, etc) to get name with digest, or you can turn off this feature with config.assets.digest = false

Digest not generated after compiling assets

After executing rake assets:precompile in production environment it show a message saying
Generated non-digest assets in 485ms
I also tried rake assets:precompile:all, rake assets:precompile:primary but still it isn't generating digest for assets. Here's my production.rb file.
Gullak2::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.serve_static_assets = false
# 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
config.assets.logger = Logger.new($stdout)
# Defaults to nil and saved in location specified by config.assets.prefix
# config.assets.manifest = YOUR_PATH
# 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

# config.force_ssl = true

# config.log_level = :debug
# Prepend all log lines with the following tags
# config.log_tags = [ :subdomain, :uuid ]
# Use a different logger for distributed setups
# config.logger = ActiveSupport::TaggedLogging.new(SyslogLogger.new)
# Use a different cache store in production
# config.cache_store = :mem_cache_store
# Enable serving of images, stylesheets, and JavaScripts from an asset server
# config.action_controller.asset_host = "http://assets.example.com"
# Precompile additional assets (application.js, application.css, and all non-JS/CSS are already added)
config.assets.precompile += %w( merchant.css merchant.js)
config.assets.initialize_on_precompile = false
# Disable delivery errors, bad email addresses will be ignored
# config.action_mailer.raise_delivery_errors = false
# Enable threaded mode
# config.threadsafe!
# 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
end
Try the following code out :-
task non_digested: :environment do
assets = Dir.glob(File.join(Rails.root, 'public/assets/**/*'))
regex = /(-{1}[a-z0-9]{32}*\.{1}){1}/
assets.each do |file|
next if File.directory?(file) || file !~ regex
source = file.split('/')
source.push(source.pop.gsub(regex, '.'))
non_digested = File.join(source)
FileUtils.cp(file, non_digested)
end
end
It was my fault. I didn't look through the log generated by rake assets:precompile RAILS_ENV=production command. It generates assets twice. First it generates assets with digest and after that it generates the non-digested assets.
I was reading only the last message which said Generated non-digest assets

Rails: "rake assets:clean" doesn't remove files

I found out that I need to run the following to clean my public/assets directory
rake assets:clean
but it doesn't really do anything! it delete 4 files out of almost a 100 and it stopped
I was also asked to post my production.rb file when posting the question.

Hope someone can help! :)
Your issue is probably because of Rails Asset pipelining which Rails in production precompiles your js files to public/assets hence your js file is either not loaded or is an older version. Look at this answer to a similar issue to what you are having.

How to get asset caching working

I am trying to upgrade to cedar / asset pipeline and am stuggling with something.
Everything renders fine, but my app seems noticeably slower. Looking thorugh my logs I see tons of items like these:
2012-03-15T17:03:02+00:00 app[web.1]: cache: [GET
/assets/application.js] miss 2012-03-15T17:03:02+00:00 app[web.1]:
cache: [GET /assets/down_arrow.gif] miss 2012-03-15T17:03:02+00:00
app[web.1]: cache: [GET /assets/application.css] miss
I would expect these to be hits -- right?
My production.rb
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
# For nginx:
config.action_dispatch.x_sendfile_header = 'X-Accel-Redirect'
# I also tried these
# config.action_dispatch.x_sendfile_header = "X-Sendfile"
# config.action_dispatch.x_sendfile_header = nil
config.cache_store = :dalli_store
My application.rb
...
config.assets.enabled = true
# Version of your assets, change this if you want to expire all your assets
config.assets.version = '1.0'
config.assets.initialize_on_precompile = false
config.active_support.deprecation = :log
Note: that assets:precompile works fine on deploy:
-----> Preparing app for Rails asset pipeline
Running: rake assets:precompile
-----> Rails plugin injection
Injecting rails_log_stdout
Injecting rails3_serve_static_assets

I raised a support ticket with heroku and here was there response:
I'd give this a shot:
http://jackchu.com/blog/2011/09/20/rails-asset-pipeline-content-delivery-networks-and-rack-cache/
Recent investigations Rack::Cache and memcached/dalli seems to be
broken in Rails 3.1+.
That seemed to do the trick. I look forward to the interaction between Rack::Cache and dalli to be fixed, but in the mean time I will follow #jackchu approach
