Access to calling chain associations

Assuming that we have a player model and a game model and that each game has multiple players as described below.

class Game < ActiveRecord::Base has_many :players

def some_method # # which player called me? # end

end

class Player < ActiveRecord::Base belongs_to :game end

Is there a way to determine which player called some_method in the game when called through one of the players and without explicitly adding the player to the argument list? For example ...

Player.find(id).game.some_method();

nope (at least nothing sensible I can think of). 'Which player called me' might not even be defined (eg if you do Game.find (123).some_method.
