Sprockets tends to be quite verbose in the (dev) log by default under Rails 3.1 (RC1):

I'd like to either reduce the level of verbosity or disable it altogether.
I'm assuming there is a clean way to disable or reduce the verbosity of the logging by adding a config line in either environment.rb
or development.rb
similar to config.active_record.logger = nil
which silences ActiveRecord SQL statements.
Place the following code in config/initializers/quiet_assets.rb
if Rails.env.development?
Rails.application.assets.try(:logger=, Logger.new('/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/}
call_without_quiet_assets(env)
ensure
Rails.logger.level = previous_level
end
alias_method_chain :call, :quiet_assets
end
end
Updated: now works for Rails 3.2 too (previous attempt fixes before_dispatch
now we're going for the root rack call
instead)
Update: A proper Rack middleware solution (instead of fragile alias_method_chain
) from @macournoyer https://github.com/rails/rails/issues/2639#issuecomment-6591735
Take a look at https://github.com/evrone/quiet_assets and just include it into your Gemfile
For lazy: gem 'quiet_assets', group: :development
For Rails 3.2, add config.assets.logger = false
to your development environment configuration file, typically found at config/environments/development.rb
. See #4512
Two things is enough:
1. config.assets.debug = false
in config/enviroments/development.rb
2. rake assets:precompile
. See comment by @oma below; this is not needed
Thats all!
Eventually, it will be config.assets.logger = nil
but that part is currently stubbed on master (not done yet)
I know it's an ugly and temporary solution but i use this :
tail -f log/development.log | grep -vE 'asset'
Many people are confused about the use of config.assets.logger = false
. Here is what it does and what it doesn't do.
According the source documentation:
Setting
config.assets.logger
to false will turn off served assets logging.
However this probably is not what you think it is. It only disables sprocket 'serving' logs, not Rails actionpack request logs. The Rails maintainer explains this clearly here: https://github.com/rails/rails/issues/4569#issuecomment-3594500
Taking example from the link, logs like this are disabled:
Served asset /jquery.isotope.js - 304 Not Modified (0ms)
But logs like this are not
Started GET "/assets/jquery.isotope.js?body=1" for 127.0.0.1 at 2012-01-20 23:16:46 -0500
config.assets.quiet = true
This is the latest way to go.
in development.rb in config/environments you'll find the line config.assets.debug = true
. Switch that to false
and most of the asset load output will be gone. On my system only the two requests for application.css and .js remain.
Rails.application.assets.logger = Logger.new(RUBY_PLATFORM =~ /(win|w)32$/ ? "NUL" : "/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'].index("/assets/") == 0
call_without_quiet_assets(env).tap do
Rails.logger.level = previous_level
end
end
alias_method_chain :call, :quiet_assets
end
it's the same code @choonkeat added. I just included to work under windows as well.
In config/environments/development.rb please add:
config.assets.debug = false
config.assets.logger = false
This will help toward your problem.
Lograge for the win- It kills Rails' annoying logger defaults out of the box (e.g. logging assets, logging partial rendering), and is customizable if you want to add/remove specific items.
The below mentioned link solution helps:
https://github.com/evrone/quiet_assets
Also as below it's working fine for me
3.1 (only) (3.2 breaks before_dipatch)
app\config\initializers\quiet_assets.rb
Rails.application.assets.logger = Logger.new('/dev/null')
Rails::Rack::Logger.class_eval do
def before_dispatch_with_quiet_assets(env)
before_dispatch_without_quiet_assets(env) unless env['PATH_INFO'].index("/assets/") == 0
end
alias_method_chain :before_dispatch, :quiet_assets
end
3.2 Rails - Rack root tap approach
app\config\initializers\quiet_assets.rb
Rails.application.assets.logger = Logger.new('/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'].index("/assets/") == 0
call_without_quiet_assets(env).tap do
Rails.logger.level = previous_level
end
end
alias_method_chain :call, :quiet_assets
end
In config/environments add config.log_level = :error
to the .rb files you want to change. This will change the log settings to error only.
I hope this helped!
