object has two collections of objects of the same type

I want to have my object class have both a collection of doc objects
called "reports" and one called "docs". How do I specify two
different arrays of the same type of object?

class Whatever < ActiveRecord.Base
  has_many :docs
  has_many :reports, class_name => "Doc", foreign_key => "something_id"

whatever_id is a field in docs

class Doc < ActiveRecord::Base
  belongs_to :whatever
  belongs_to :something, class_name => Whatever

Then you can say whatever.docs, whatever.reports and doc.whatever and

I have this in my new method


how do I do the same thing for a collection called reports of the doc
type also?


I think.
