Logging in Rails

When you’re living in the Active* world of Rails (ActiveRecord, ActionController, etc.) you always have access to the ubiquitous logger method. But step outside and you’re stuck dealing with the awkward, and uncomfortable RAILS_DEFAULT_LOGGER global. Often time’s I find myself taking one or both of the following approaches depending on the class I’m writing.

class MadeUp
  class << self
    def logger
      RAILS_DEFAULT_LOGGER
    end
  end

  def logger
    RAILS_DEFAULT_LOGGER
  end
end

Now I know, neither of the methods are complex or long, but how often do you want to type that same handful of lines (and doesn’t it just make your code ugly)? Enter my latest and greatest contribution to the world: Loggable.

module Loggable
  module ClassMethods
    def logger
      RAILS_DEFAULT_LOGGER
    end
  end

  module InstanceMethods
    def logger
      RAILS_DEFAULT_LOGGER
    end
  end

  def self.included(receiver)
    receiver.extend         ClassMethods
    receiver.send :include, InstanceMethods
  end
end

Object.send :include, Loggable

Remember to require it somewhere in your code.
