plugin for finding duplicates

hi

is there a plugin or something else which could assist in finding duplicates in a model / table?

even with validations, users tend to enter data twice / wrong (for whatever reasons...)..so i was wondering if there is something out there to find these entries, preferably across multiple columns thx tom

Never heard of a plugin to do this, but one thing that can help is adding :disable_with to submit buttons - you'd be amazed how many users double-click (or more) buttons. You'll notice this if you're using timestamps and you see a stack of identical records created <1s apart.
