Question

Hopefully this will help save my fellow programmer friends some head banging :D

I was uploading the files to S3, I didn't realize that the manifest wasn't loaded by Rails. You can have all your production settings right (like above and in other threads), but if you don't have the manifest.json file readable by Rails, it will still generate /javascript/* (example) urls.

I was still having trouble with multi_json gem's latest version, so I downgraded it to 1.7.8 and it works fine.

gem 'multi_json', '1.7.8'

That's so it can read the manifest.json file which rake assets:precompile creates.

There is a debate on this sprockets thread https://github.com/rails/sprockets-rails/issues/107 on whether your manifest file should be in git or just on a deploy script, do what suits you best, just make sure it is findable in:

/public/assets/manifest.json 

or specifiy it yourself with

config.assets.manifest = '...'

That may or may not be depricated.

Cheers!
