Set logging levels in Ruby on Rails

Question

I'm using following code to configure logging in my Ruby on Rails application:

environment.rb:

Rails.logger = Logger.new(STDOUT)  class Logger   def format_message(severity, timestamp, progname, msg)     "#{timestamp.to_formatted_s(:db)} #{severity} #{msg}\n"   end end 

I'm trying to set the logging level to warn now using

config.log_level = :warn 

in my production.rb, but it doens't seem to work. Am I missing something here?

If I put Rails.logger.level = 4 in my environment.rb, it does seem to work. But I would like to configure things in my environment initializers.

According to the official documentation, you should be using:

config.log_level = :warn # In any environment initializer, or Rails.logger.level = 0 # at any time 

If neither of those work for you, try:

config.log_level = Logger::WARN 

And if that doesn't work, try:

config.logger.level = Logger::WARN 

Note: The final method appears to be conflating the two official strategies, but works in some situations
