Hidden field wich unique ID. If the ID is submitted twice, omit the

entry
But suppose the user clicks submit, instantly recognizes an error in
the information, hits stop, corrects the error, and clicks submit
again?
If you discard the *second* submission, there is now a discrepancy
between what the user intended and what you've stored. Uh-oh.
Might want to give that a little more thought :-)
Are you trying to trap a "bounce" here -- a double-click because of
machine or user error that is being interpreted as two separate submit
events? You can easily trap those by adding :disable_with =>
'Saving...' to your button tag. Only the first click will be accepted,
and the button will gray out and stop accepting input after that.
Happens at the JavaScript level, so the response will be very nearly
immediate.
