Very useful example. Does it mean, we can use it also *scope* or on *default scope* ? Will it be a good choice although to use scope relation if it fits any query, with some tailoring using *except* ? -- ================ Regards, Arup Rakshit ================ Debugging is twice as hard as writing the code in the first place.
