Rails - how to disable all console logging?

Coming from a javascript background, I find the command line while running rails to be cluttered. Every time something happens, my command line is filled with a bunch of crap. E.g:

[2013-06-19 20:25:53] WARN  Could not determine content-length of response body.
 Set content-length of the response or set Response#chunked = true

How do I turn this off so that I only see my own logs(and errors, of course)?

Any help is appreciated!

Solution

./.env

usually file .env is used to store all important / secret properties of your application environment. Create .env if not exist and add code:

RAILS_LOG_TO_STDOUT=true

./config/environments/*.rb

edit your environment file (e.g. ./config/environments/development.rb) to create a disconnectable logging system.

Rails.application.configure do

  # ...

  if ENV['RAILS_LOG_TO_STDOUT'] == 'true'
    logger           = ActiveSupport::Logger.new(STDOUT)
    # To support a formatter, you must manually assign a formatter from the config.log_formatter value to the logger.
    logger.formatter = config.log_formatter

    # config.logger is the logger that will be used for Rails.logger and any 
    # related Rails logging such as ActiveRecord::Base.logger.
    # It defaults to an instance of ActiveSupport::TaggedLogging that wraps an 
    # instance of ActiveSupport::Logger which outputs a log to the log/ directory.
    config.logger    = ActiveSupport::TaggedLogging.new(logger)

    # config.log_level defines the verbosity of the Rails logger. 
    # This option defaults to :debug for all environments. 
    # The available log levels are: :debug, :info, :warn, :error, :fatal, and :unknown
    #config.log_level = :debug

    # config.log_tags accepts a list of: methods that the request object responds to,
    # a Proc that accepts the request object, or something that responds to to_s. 
    # This makes it easy to tag log lines with debug information like subdomain and request id -
    # both very helpful in debugging multi-user production applications.
    config.log_tags = [:request_id]
  end
end

Usage

set RAILS_LOG_TO_STDOUT=true in .env to turn on console logger

delete or comment out line RAILS_LOG_TO_STDOUT=true, or set RAILS_LOG_TO_STDOUT=false in .env to turn off console logger

Change the log level in config/environments/development.rb, and/or testing.rb:

config.log_level = :error

The log levels available are: :debug, :info, :warn, :error, :fatal, and :unknown, which correspond to the integers 0-5.

Try changing the log level, which is info by default.
