Subject: remove duplicates of array of  object based on a attribute

hi all,
          how to remove duplicates of an array of objects based a
attribute of the object. For ex
           i am having an array of  ruby beans named diagnoses . i want
remove duplicates from the based on the diagnoses id. assume diagnoses
have attributes id and weightage .So for two diagnoses with same id and
different weightage , the diagnoses with lower weightage should be
removed.
           Can anyone help me??
