Question

I’m trying to inline CSS into my layout. I’m currently using

= Rails.application.assets.find_asset(’embedded.css’).body.html_safe

However, the CSS returned is not compressed. I verified what .digest_path asset file exists, and is properly compressed.

I can, of course, write a helper that will check if current on-disk compressed asset file exists for a given asset, and use it. However, I think find_asset actually compiles a CSS asset each time it is called — not good in production. I hope a cleaner solution exists for this issue.

Answer 1

If assets are to be rebuilt in Production, production has to have access to minifiers. By default, Gemfile has something like this:

group :assets do
  gem 'sass-rails'
  gem 'coffee-rails'
  gem 'therubyracer'
  gem 'uglifier'
end

Need to remove :group assets do, so these gems are included in production environment too. Then, find_asset rebuilds the asset and minimizes/compresses it on the first call, and caches it.
