class Pet
	extend ActiveModel::Callbacks

  define_model_callbacks :test

  before_test :motherfucker

  after_test do
  	puts "after that"
  end

  around_test do
  	puts 'around that'
  end

  def lala
  	puts "just a test"
  	# _run_test_callbacks do
  	# 	puts "real work"
  	# end

  	run_callbacks :test do
  		puts "real work"
  	end

  	
  	run_callbacks :test do
  		puts "real work"
  	end
  end

  def motherfucker
  	puts "before that"
  end
end
