Log::Minimal - convenient logger wrapper for your rails app inspired by Log::Minimal CPAN module

log_minimal.rb

module Log
  module Minimal
    [:fatal, :error, :warn, :info, :debug].each do |method|
      define_method "#{method}f" do |message|
        time = Time.now.iso8601
        level = method.to_s.upcase
        caller = "%s#%s:%s" % [self.class, action_name, caller(1)[0].scan(/:(\d+):/)]
        
        logger.send(method, "%s [%s] %s %s" % [time, level, caller, message])
      end
    end
  end
end

How to use it:

in application.rb or application_controller.rb

class ApplicationController < ActionController::Base
  include Log::Minimal
end

in your foo_controller.rb

class FooController < ApplicationController
  def index
    infof("foo bar baz")
  end
end

then you can get informative log message :)
