#	Simply extracted some code to clean up model.
#	I'd like to do this to all of the really big classes
#	but let's see how this goes first.

module StudySubjectPii

#	Must delay the calls to these ActiveRecord methods
#	or it will raise many "undefined method"s.
base.class_eval do

		[first_name, middle_name, last_name ]
	end

	#	Returns string containing study_subject's first, middle and last initials
	def initials
		childs_names.delete_if(&:blank?).collect{|s|s.chars.first}.join()
	end

	#	Returns string containing study_subject's first, middle and last name
	#	Use delete_if(&:blank?) instead of compact, which only removes nils.
	def full_name
		fullname = childs_names.delete_if(&:blank?).join(' ')
		( fullname.blank? ) ? '[name not available]' : fullname
	end

	#	TODO what? no maiden name?

#	TODO I hate this.  It is revolting.  More?  Yes, please.
#
	#	I don't know if I still need this
	#	commented out 20101014
	#	uncommented 20101014

		#	added to_date to fix sqlite3 quirk which doesn't	(why am I using sqlite3?)  old comment?
