It seems this functionality is not baked in, but I just want to confirm before I roll my own solution.

To clarify, I'm wanting to move the associations from the old object to the new, not duplicate them.

My hand-rolled solution is this:

  amoeba do
    # include_association :transactions (duplicates)
    # include_association :payments (duplicates)
    customize(lambda { |orig, new|
      orig.transactions.each { |t| t.invoice = new && t.save!}
      orig.payments.each     { |p| p.invoice = new && p.save!}
    })

Is there a better way?
