Safer Paperclip id_partition interpolation for mongoid

	# Googling for how to implement a good Paperclip id_partition for mongoid, you might find -
	# attachment.instance.id.to_s.scan(/.{4}/).join("/")

	# There are problems with this. Because mongoid ID's are hex strings, a 4-character string can contain
	# 4^16 or 65536 values. Usually with id partition we're trying to make sure no directory ever holds more
	# than 32k files, so 64k is potentially dangerous. To be safe we need to drop to 3 characters or 4096 values.

	Paperclip.interpolates :id_partition do \|attachment, style\|
	attachment.instance.id.to_s.scan(/.{3}/).join("/")
