Not working on production

[heidiv]

Hello! I'm sure this is something on my end, not yours, but I was wondering if you had any insight as to why retina_tag would work beautifully on my local development environment, but not my production server?

On the server, data-hidpi-src & data-lowdpi-src attributes are not being added to tags. I checked my public/assets dir and the @2x versions are there. The retina_tag gem is installed. Other thoughts? Thanks in advance!

I am also having this issue. I have used the gem before on other projects, but it seems to be broken on my latest.

rails 4.2.5
ruby 2.3.0

Ill have to see what might have changed in latest rails to cause this.

Here's the cause of the issue: rails/sprockets-rails#237

In production, Rails.application.assets is only set if config.assets.compile is enabled (and it's not enabled by default in production)

You can get the same info using Rails.application.assets_manifest, although you have to basically implement the find_asset logic yourself

I'm trying to fix this myself right now, since I need to fix this for my current project.
I'll submit a PR if I'm successful
