ActionController::RoutingError (No route matches [GET] "/assets/images/control_top.png")

what can i do to resolve this problem?

Answer 1

In production env, Rails will not be responsible for serving static assets. Therefore, you are getting this error.

This is controlled by this setting in config/environment/production.rb in your application:

config.serve_static_assets = false

You can set to that true

or try this

rake assets:precompile 

command (compiles and copies images, css and js from app/assets to public/.

Answer 2

If you upgrade to a new version of Rails (Rails 4 and Rails 3.2.16 come to mind), and you suddenly start to see this error, it is likely that your stylesheet is pointing to the non-fingerprinted, non-cached version of the files. If you are using the asset pipeline, in order to take advantage of it, you need to use the new helpers that point to the fingerprinted, cached version of the files. To do so, you'll need to either embed erb in your css file, or use sass.

Incorrect (uses sass):

.class
  background: url('asset.png') no-repeat

Correct (uses sass):

.class
  background: image-url('asset.png') no-repeat
