I have a strange behaviour with compiled assets when running a simple draft app locally: RAILS_ENV=production rake assets:precompile The aove command generated some css and js with finger printed values: i.e. application-43dcf2bdff355d2c3053e2aade23881a.css application-c67be452a576850d0c11559f908180e3.js etc. Run in production: rails s -e production There are no CSS fiound ! When observing the html source: <link href="/assets/application-43dcf2bdff355d2c3053e2aade23881a.css" media="screen" rel="stylesheet"> There are the following errors in the console as well: F, [2014-02-18T16:56:36.417436 #4036] FATAL -- : ActionController::RoutingError (No route matches [GET] "/assets/application-43dcf2bdff355d2c3053e2aade23881a.css"): actionpack (4.0.2) lib/action_dispatch/middleware/debug_exceptions.rb:21:in `call' actionpack (4.0.2) lib/action_dispatch/middleware/show_exceptions.rb:30:in `call' railties (4.0.2) lib/rails/rack/logger.rb:38:in `call_app' railties (4.0.2) lib/rails/rack/logger.rb:20:in `block in call' activesupport (4.0.2) lib/active_support/tagged_logging.rb:67:in `block in tagged' activesupport (4.0.2) lib/active_support/tagged_logging.rb:25:in `tagged' activesupport (4.0.2) lib/active_support/tagged_logging.rb:67:in `tagged' railties (4.0.2) lib/rails/rack/logger.rb:20:in `call' actionpack (4.0.2) lib/action_dispatch/middleware/request_id.rb:21:in `call' rack (1.5.2) lib/rack/methodoverride.rb:21:in `call' rack (1.5.2) lib/rack/runtime.rb:17:in `call' activesupport (4.0.2) lib/active_support/cache/strategy/local_cache.rb:83:in `call' rack (1.5.2) lib/rack/sendfile.rb:112:in `call' railties (4.0.2) lib/rails/engine.rb:511:in `call' railties (4.0.2) lib/rails/application.rb:97:in `call' ... Any idea ? What is wrong here ? Why Rails 4 didn't see my assets ? It is just a simpe app with one generated scaffold for posts, nothing special, no additional configurations added . really weird. -- You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.
