# this pattern of declaring methods in a module and then including into a class means that the methods can be used directly from the module
#   eg. ExtendObject::attr_from_json(json,object)
# or on the class it is included into
#   eg. model.attr_from_json(json)
module ExtendObject

	module_function # this makes the methods accessible on the module as well as instances when the module is included into a class

	public

	def attr_from_json(aJsonObject,aObject=nil)   # only give second argument when used like ExtendObject::attr_from_json
		aObject ||= self
		rubyObj = JSON.parse!(aJsonObject)
		rubyObj.each do |k,v|
			aObject.send k.to_sym,v
		end
		aObject
