Hi all, I am trying to do little bit beyond params… means I try to assign one active record object to another object as update attributes both have same field. Before that I want to remove id field from old object. Is there way to remove attributes from object and to assign new object?? If any one knows… ---

clone() would do that Returns a clone of the record that hasn‘t been assigned an id yet and is treated as a new record. Note that this is a “shallow” clone: it copies the object‘s attributes only, not its associations. ---
