Silencing Asset Pipeline Details in Rails Logs

The asset pipeline details can get quite extensive in Rails logging and since the details you are analyzing typically are not related to the loading of assets, you may want to silence them, or prevent them from logging – especially since you can always turn logging back on if you run into asset troubles.

I’ve found three ways to do so:

  1. you can use the Quiet Assets gem

These other two were mentioned on Stack Overflow, but I was not able to get them to work:

  1. you can add this as an initializer in config/initializers/quiet_assets.rb:
if Rails.env.development?
  Rails.application.assets.logger ='/dev/null')
  Rails::Rack::Logger.class_eval do
    def call_with_quiet_assets(env)
      previous_level = Rails.logger.level
      Rails.logger.level = Logger::ERROR if env['PATH_INFO'] =~ %r{^/assets/}
      Rails.logger.level = previous_level
    alias_method_chain :call, :quiet_assets

3.  if you are using Rails 3.2 or above, you can include this setting in config/environments/development.rb:

config.assets.logger = false
