Question

I\'m trying to put my app into production and image and css asset paths aren\'t working.

Here\'s what I\'m currently doing:

• Image assets live in /app/a

Even we faced the same problem where RAILS_ENV=production bundle exec rake assets:precompile succeeded but things did not work as expected.
We found that unicorn was the main culprit here.

Same as your case, even we used to restart unicorn after compiling the assets. It was noticed that when unicorn is restarted, only its worker processes are restarted and not the master process.
This is the main reason the correct assets are not served.

Later, after compiling assets, we stopped and started unicorn so that the unicorn master process is also restarted and the correct assets were getting served.
Stopping and starting unicorn brings around 10 secs on downtime when compared to restarting the unicorn. This is the workaround that can be used where as long term solution is move to puma from unicorn.
