ruby-on-rails nginx capistrano asset-pipeline

Rails assets missing after Capistrano deploy

I'm building a VPS, and it's deployed via Capistrano, database connected etc, but there are no assets available to the page - it is basic html only.

The assets appear to be compiled, and exist in the shared directory.

From the page html:

<link href="/assets/application-a1b5d69aeaff709fd3dce163c559b38b.css" media="all" rel="stylesheet" type="text/css" />
<script src="/assets/application-0ebd07089629f8c6880dddfb688d525d.js" type="text/javascript"></script>

The asset files appear to exist in the shared directory:

assay@assaypipeline:~/apps/assay/shared/assets$ ls application-  a1b5d69aeaff709fd3dce163c559b38b.css
application-a1b5d69aeaff709fd3dce163c559b38b.css

When I view, source and then click on the hyperlink to the asset path, I get a 404 not found from Nginx.

SOLUTION

Thanks to Martin M (accepted answer) for help. The steps I took, from the ~/apps/(app name)/current directory on the server.

$ bundle install
$ RAILS_ENV=production bundle exec rake assets:precompile
$ sudo service nginx restart

Obviously it would be better to include this in the Capistrano recipe.

*EDIT - Capfile *

load 'deploy'
load 'deploy/assets'
load 'config/deploy'

Solution

Your precompiled assets should reside in public/assets, see rails guides
normally you create them by running

RAILS_ENV=production bundle exec rake assets:precompile

as part of your deployment.
The shared stuff is to provide old stuff over several deploys.
