Rails App Not Serving Assets in Production Environment
My app works fine when run in development environment. In production (rails server -e production), the browser can't access the css and js files and on the console there are messages like:
I, [2013-07-27T21:00:59.105459 #11449] INFO -- : Started GET "/javascripts/application.js" for 99.102.22.124 at 2013-07-27 21:00:59 +0000

The app does not use a database, so I have disabled ActiveRecord. Snippets of the config files:

I apologize for posting so much info. I felt the info might be relevant.
p.s. I have only half baked knowledge of rails, so bear with me. Thanks~
Solution 1:
When testing locally your production environment, you have to compile the assets locally. Simply run the command below:
RAILS_ENV=production bundle exec rake assets:precompile
It will generate all the assets under public/assets.
Next, you have to tell Rails to serve the assets itself. Server software (eg. Nginx or Apache) do it for you on environments like Heroku, but locally you should let Rails do it. Change this in your production.rb:
config.serve_static_assets = true
But make sure you set it back to false before pushing your code to production!
Solution 2:
This sounds like to the problem I was having.
I found a blog that suggests this is a bug in the Rails 4.0.0 asset pipeline, and is inexplicably mitigated by setting...
config.assets.compile = true
... in config/environments/production.rb
Aside from somehow kicking the asset pipeline in to actually working, that setting will turn on live-compilation of assets. That is normally a bad thing for performance in production, but if you still manually precompile assets when you deploy, with
rake assets:precompile
... the live-compilation should never happen (because the necessary assets have already been precompiled).
I hope this helps :)
Solution 3:
As previously noted config.serve_static_assets is deprecated and replaced by config.serve_static_files. If one examines config/environments/production.rb for Rails-4.2 then one finds this:
# Disable serving static files from the `/public` folder by default since
# Apache or NGINX already handles this.
config.serve_static_files = ENV['RAILS_SERVE_STATIC_FILES'].present?
The implication being that setting and exporting (in BASH) the environment variable export RAILS_SERVE_STATIC_FILES="to any value whatsoever" in a session prior to running rails s -e production will give the desired result when testing locally and also will avoid having to remember to recode production.rb before pushing to the production host.
Solution 4:
In production.rb change the setting:
rails 3.x
config.serve_static_assets = true
rails 4.x
config.serve_static_files = true
Solution 5:
Check for a file like this:
public/assets/.sprockets-manifest-3f7771d777ceb581d754e4fad88aa69c.json
If you are pushing precompiled assets to a production server there is a chance that you are preventing hidden 'dot' files being pushed and this essential file won't make it into production.
In my environment I need to precompile assets in an integration environment and push these to production so that there is no need to compile the assets on the production machine. I was erroneously blocking all hidden files from being pushed to production machine.
To see if this answer works for you, check your generated HTML source in a browser from the production server to see if the assets path has been generated. If you see your script tag like this:
<script data-turbolinks-track="true" src="/javascripts/application.js"></script>
check the src attribute. It should start with /assets/javascript. In this case it starts with /javascript which indicates Rails does not think any of the assets have been precompiled.
I corrected this by updating my push to production (currently rsync), ensuring I push the .sprockets-manifest* file after precompiling on my integration server.
Also, I use standalone Passenger as my integration test server, rather than Webrick, since it handles more realistic serving of static files.
