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();

Thanks

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.
