I had exactly this issue under Rails 4. Unless you precompile the assets in production mode, it creates fingerprinted filenames, but doesn't use them in the helpers (if I got that the right way round).

<div><div><br></div><div>I thought this was pretty damn stupid, and filed a bug: <a href="https://github.com/rails/rails/issues/10551">https://github.com/rails/rails/issues/10551</a>. In my view, it should be consistent wherever you are compiling. Fine if dev mode doesn't minify or fingerprint, but make it consistent. I was told that it should only now be done in production, end of story. Not a very useful solution, I think - too much room for pilot error.</div><div><br></div><div>I had a quick go at a (far too simple) PR on sprockets which would dump out a text warning if not in production mode, but I ran out of time to make it properly robust.</div><div><br></div><div>cheers,</div><div>James</div><div><br></div></div>

<div><br></div><div>Second, our CSS is not being minified, and we have no idea why. If you clone <a href="https://github.com/jcoglan/rails_assets">https://github.com/jcoglan/rails_assets</a>, and run:</div><div><br></div>
<div> $ bundle exec rake assets:precompile</div><div><br></div><div>then it does not minify the code in public/assets, which we assumed was because config/environments/development.rb sets config.assets.debug = true. If you compile in production:</div>
<div><br></div><div> $ RAILS_ENV=production bundle exec rake assets:precompile</div><div><br></div><div>then it does minify the CSS. So, we figured there must be a config difference and that would explain why our code is not being minified in our production apps that have been upgraded from Rails 3 to 4. So, I deleted all the code from config/environments/{development,production}.rb and it still does the same thing: no minification in development mode, and minified code in production. So it doesn't seem like a config thing -- is this difference baked in Rails? What am I doing wrong? Why would our production apps not be minifying their CSS?<br clear="all">
