I'm currently having the exact same problem as described in this post: Rails not serving assets in production or staging environments.
I am running Rails 4.0.4 in production environment on Windows 7 (so that could easily be the problem, can't use Linux unfortunately). I have run rake assets:clobber to make sure everything is cleaned up and and then RAILS_ENV=production rake assets:precompile and it succeeds without errors or warnings. All the files appear in my public/assets folder and using Windows explorer I can view the text in application.js and application.css, and images display correctly. However when I try to visit localhost:3001/assets/application.js it is blank, same with application.css, and image files come up with an error. I have restarted the server each time after changing settings and precompiling.
When I look at the logs it says the page renders successfully, there are no "No route matches" errors like I have seen in other posts. So the assets are being found, but for some reason they aren't being properly served.
Here is my production.rb:
ABC::Application.configure do
config.cache_classes = true
config.eager_load = true
config.consider_all_requests_local = false
config.action_controller.perform_caching = true
config.action_dispatch.x_sendfile_header = "X-Sendfile"
config.serve_static_assets = true
config.action_mailer.default_url_options = { :host => '' }
config.i18n.fallbacks = true
config.active_support.deprecation = :notify
config.assets.js_compressor = :uglifier
config.assets.css_compressor = :sass
config.assets.compile = false
config.assets.digest = true
end
Any help would be much appreciated, I've been stuck on this for nearly two days!
Just as I finished typing up this question, I finally came across another post which said the headers were being set but there was no body, which sounded like my problem. They were using nginx and fixed the problem by changing the following:
# 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
And seeing as I'm not using either Apache or nginx, I commented out both lines and finally my assets were served. Seems obvious in hindsight but I thought I would post this anyway in case it helps anyone else having the same problem.

I'm at my wits end with this. It seems all of the newer rails apps I make its set a couple of configs in environments/production.rb, deploy and move on with my life. But now we're migrating a few rails apps to a new server and it seems all of them have this issue when deploying to production.
What appears to be happening is that neither my javascripts or stylesheets are getting compiled. And I see none of the styles for the app and the javascript does not work.
config/application.rb:
require File.expand_path('../boot', __FILE__)
require 'rails/all'
if defined?(Bundler)
Bundler.require(:default, :assets, Rails.env)
end
module MyApp
class Application < Rails::Application
... omitted code ...
# 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.generators.stylesheet_engine = :scss
end
end
config/environments/production.rb:
MyApp::Application.configure do
# 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 = 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
... omitted code ...
end
In my application-<...>.js:
// This is a manifest file that'll be compiled into including all the files listed below.
// Add new JavaScript/Coffee code in separate files in this directory and they'll automatically
// be included in the compiled file accessible from http://example.com/assets/application.js
// It's not advisable to add code directly here, but if you do, it'll appear at the bottom of the
// the compiled file.
//
//= require jquery
//= require jquery_ujs
//= require_tree
;
And my application-<...>.css is completely empty. What am I missing?
So after a long half day yesterday and about an hour today, I suddenly realized something... I ran into this before.
Sure enough... Updating rails to 3.2.14 and deploying again fixed the whole thing.
After upgrading to Rails 4, public/assets/manifest.yml is not generated anymore. Instead the different formatted manifest-(fingerprint).json is present.
But it seems to me that the server is still looking for the old manifest.yml format, ignoring the .json version?
I see other questions based on similar problems, but they seems to be sovled by upgrading to Rails 4, adding rails_12factor to gem file, setting serve_static_assets = true, etc., but none of these solutions seems to have any effect in my scenario.
I am tired and uninspired due to this annoying problem, any help will be appreciated!

I am using Angular and their ui-router, and this is the part of my routes.js.coffee where the test.html is linked:
.state "root",
url: "/"
views:
"root":
controller: "ApplicationController"
templateUrl: "/assets/layouts/test/test.html"
I have also tried precompiling locally, but as I am using Rails 4 here as well, still no manifest.yml is created, only the .json version.
Of course, everything is working just perfectly in development...
So my actual cuestion:
How do I make Heroku recognize and use the manifest-(fingerprint).json -file, or alternative ways to make this work?
The answer is, that Heroku already does recognize and use the manifest-(fingerprint).json -file. The "workaround" in my comment above, is the proper way to reference these files, and by doing so, the manifest-file is used the way it's ment to be used.
Renaming the file with the internal link to .erb, and referencing like this: templateUrl: "<%= asset_path('layouts/test/test.html') %>" does the trick. All internal files, images, and html -files should be referenced like this.
It's all described very thoroughly here: Asset-pipeline guide
It seems so simple and straightforward now, but I really spent a lot of time trying to get the wrong way around this from the beginning.
I hope this answer can save the time for someone else.
I have hosted a LocomotiveCMS app on Heroku. I've thereafter been working directly on the Heroku MongoHQ database, and have completed the wesbite.
I've then set the development database on my local machine to connect to the MongoHQ database used by the HerokuApp, so the local machine uses the actual data that's on the web. But the assets (CSS and JS files ) donot get accessed properly. Even though I've set up AWS Credentials.
So, when I access the CSSS+JS files on my local machine, I get the files, but with no content, i.e. blank file. I also dont get the AWS links for the assets, as I was seeing on the Heroku server.
Is it something to do with asset precompilation. I have set up the Heroku exactly as described here: http://doc.locomotivecms.com/guides/hosting/heroku-hosting
The production.rb file is as follows:
Testapp::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 = false
# Compress JavaScripts and CSS
config.assets.compress = true
# Don't fallback to assets pipeline if a precompiled asset is missed
config.assets.compile = false
# Generate digests for assets URLs
config.assets.digest = true
# 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
# Force all access to the app over SSL, use Strict-Transport-Security, and use secure cookies.
# config.force_ssl = true
# See everything in the log (default is :info)
# 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( search.js )
# 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
config.action_mailer.delivery_method = :smtp
config.action_mailer.smtp_settings = {
:address => 'smtp.sendgrid.net',
:port => 25,
:authentication => :plain,
:user_name => ENV['SENDGRID_USERNAME'],
:password => ENV['SENDGRID_PASSWORD'],
:domain => ENV['SENDGRID_DOMAIN']
}
end
Run this in your console
bundle exec rake assets:precompile
then push to git, then to heroku
I understand why you have set the following to config.assets.initialize_on_precompile = false this makes your application run faster. However the ruby on rails guides states the following:
If you set config.assets.initialize_on_precompile to false, be sure to test rake assets:precompile locally before deploying. It may expose bugs where your assets reference application objects or methods, since those are still in scope in development mode regardless of the value of this flag.
So potentially this could be the route of your problem. Also if you want to include additional css and js you can add the following into the precompile array like so:
config.assets.precompile += ['admin.js', 'admin.css']
See following link for additional reading:
Precompiling assets
Hope this helps
Working on rails, images are not visible and giving error.
Started GET "/assets/home.png" for 127.0.0.1 at 2012-06-19 12:23:24 +0530
Served asset /home.png - 404 Not Found (24ms)
ActionController::RoutingError (No route matches [GET] "/assets/home.png"):
I have used command
rake assets:precompile
production.rb
config.assets.compress = true
config.assets.compile = false
application.rb
config.assets.enabled = true
config.assets.version = '1.0'
Thanks for any help!
Actually you cannot reference your image with /assets/home.png path.
It will work in development mode, but in production all of your assets have a fingerprint in their filename (read this http://guides.rubyonrails.org/asset_pipeline.html#what-is-fingerprinting-and-why-should-i-care-questionmark)
That's why, in assets-pipeline enabled applications you need to reference all of your assets using helper methods. Read this doc to learn about the different helpers available in Ruby, JS and Sass files: http://guides.rubyonrails.org/asset_pipeline.html#coding-links-to-assets
The lack of a fingerprint in the file request suggests that you are running this in development. I am also going to guess that this is an app upgraded from an older version of Rails.
Any images need to be in the folder /assets/images for the pipeline to work.
Also, you do not need to precompile when in development mode.
Delete the public/assets folder, delete the folder tmp/cache/assets, and restart your server.
If this images are in the correct location, it should work.
I have a new-ish rails 3.1.1 app using sass/compass with compass taking care of the sprite generations for me. In development, all works just fine. However, when I deploy, I see this entry in the log file:
Compiled team/application.css (1ms) (pid 24202)
Compiled team/forms.css (0ms) (pid 24202)
Compiled team/member.css (0ms) (pid 24202)
Compiled application.css (0ms) (pid 24202)
Completed 500 Internal Server Error in 2014ms
ActionView::Template::Error (File name too long - /home/cri/webapps-releases/cri/releases/20111121225403/app/assets/images/html,body,div,span,applet,object,iframe,h1,h2,h3,h4,h5,h6,p,blockquote...(the rest of my compiled css goes here)
My production config (for asset stuff) is pretty vanilla wiht much of it being what was generated by rails:
# Disable Rails's static asset server (Apache or nginx will already do this)
config.serve_static_assets = false
# Compress JavaScripts and CSS
config.assets.compress = true
# Specify the default JavaScript compressor
config.assets.js_compressor = :uglifier
# 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
Can anybody tell me why my compiled css is being used as the filename for the sprite?
Update: Modified title to reflect what I now think I know about this issue.
I am running rails-3.1.1 with sass-3.1.10 and sass-rails-3.1.5 and compass-0.11.3.
compass-0.11.3 does not have proper asset pipeline support you are going to want to be using the >= 0.12.alpha.3 release you can get this by doing gem install compass --pre if you are still having this issue under 0.12 then it is a bug and i would be grateful if you would file a ticket on the compass github.
Try
config.assets.debug = false
Those workarounds are true, but this bug in rails was fixed in 3.1.4. Upgrading is likely your best all-around bet.
