Active record Dynamic

A really simple question I suppose but very busy for me:

How to cast my params[:id] (through or not a temp variable) in an
activeRecord?

It seems there's been too many rails questions posted on this mailing list
today for this to be a coincidence. I wonder if someone on the rails list
is sending people to this list.
