Print a stacktrace in Ruby or Rails without raising an exception

You know what method is being and you want to figure out how it got there. Raising an exception is a bit harsh since all you want is a stack trace

puts caller

Seriously. It's that easy. If you're getting too much information you could

	# When calling a method with a splat then the parameters are passed as a comma separated list
	# When receiving arguments with a splat then they are converted into an Array
	# When using a double splat (2.0+) then the argument is converted into a Hash (i.e. named parameters)

	def foo(*args)
	p args
	end

	foo 'a', 'b', 'c'
	# => ["a", "b", "c"]

	# Call scopes directly from your URL params:
	#
	# @products = Product.filter(params.slice(:status, :location, :starts_with))
	module Filterable
	extend ActiveSupport::Concern

	module ClassMethods

	# Call the class methods with names based on the keys in <tt>filtering_params</tt>
	# with their associated values. For example, "{ status: 'delayed' }" would call

	class Avatar < ActiveRecord::Base

	attr_accessor :content_type, :original_filename, :image_data
	before_save :decode_base64_image

	has_attached_file :image,
	PAPERCLIP_CONFIG.merge(
	:styles => {
	:thumb => '32x32#',
	:medium => '64x64#',
