My question: what is the best way to find all of the items belonging to

Hi,
I'm running into a memory performance issue with Active Record

edited. However, it can occur that two people might edit the object
at the same time. Instead of locking the object down, I prefer to
tell the user how their version differs from the last version that was
committed.
Kinda like:
