Question

How can I make this method, which outputs a yellow line in the log file, accessible from everywhere (Models, Controllers, Views) in my Rails app?

def my_log(text, file = "", line = "")
  text.to_s.chomp.gsub!(/%/, "%%")
  Rails.logger.debug(sprintf("\033[32m#{file}#{line}\033[0m\033[1m\033[33m#{text}\033[0m"))
end

You could define it in Kernel (NOT recommended):

module Kernel
  def my_log(..)
    ..
  end
end

… if you really want it available anywhere.

Or, place something like this in lib/util.rb:

module Util
  def self.my_log(..)
    ..
  end
end

… and make sure to require 'util' in your config/application.rb and then you can call this anywhere:

Util.my_log(..)
