I get these message every time when page reloads.

How can i get rid of this message?

Answer 1

As DGM indicated, I was able to suppress most of these messages via modification to the development.rb file, specifically changing:

config.assets.debug = true

to

config.assets.debug = false

Answer 2

In development mode, it does not cache javascript or css, but rather reloads it on every call so you can see changes made.

You could either run another environment:

RAILS_ENV=production rails s

or set the config line in config/environments/development.rb

config.action_controller.perform_caching = true
