Running the rails server with rails s results in a huge amount of text being outputted to the screen, as it appears to be logging at the verbose :info level. When I'm debugging, sometimes I just to print a few variables to screen via awesome_print, and don't want to sift through the text.
So is there a config setting in the developlment environment file I can set to completely supress the output, (apart from the output from my ap calls)?
You can silence the assets and just get the important information for developing, just add a file in your initializers, like config/initializers/silent_assets.rb with the following code
if Rails.env.development?
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'] =~ %r{^/assets/}
call_without_quiet_assets(env)
ensure
Rails.logger.level = previous_level
end
alias_method_chain :call, :quiet_assets
end
end
You can control what gets logged in development, by customizing your config/environments/development.rb file.
Here you can find documentation on the various options.
You might want to set:
config.log_level config.assets.debug (controls assets compilation and, as a side effect, shuts down assets compilation messages)Another option would be to edit the file config/environments/development.rb, and set the log level to error:
config.log_level = :error
Then just print with awesome_print
ap {a: 1, b: 2}
If you start the server from the console like
script/rails s
In that console you will see just the output of awesome_print
None of the other answers answer the question.
Use
config.logger = Logger.new('log/development.log')
rails s --detach
