1) It's not a hash, it's an array.
2) Do you want to *prevent* it being added twice or do you just want
to ensure that all customer_student instances are unique?
If the latter, then Peter's suggestion is fine; read the Array doc to
see how to use that method.
If the former -- it's a little more work :-)
