Hmm, that's interesting, I assumed it was in subversion, now I don't
remember where I got it from. Perhaps it was posted to the mailing
list...
Since Google can't seem to find it either, I'll attach a copy...
It was originally posted to the html-widget list by Jonas Alves.
I didn't add it to svn, but didn't get round to replying to explain
why - my bad!
Unless both the form processing and any subsequent use of the form
input, are wrapped within a DB transaction - then the uniqueness check
is rather useless.
And because the form processing is usually done by the catalyst
controller - before your code can access the form - transactions
aren't very practical.
I think the uniqueness check probably belongs in the user code - the
way I've done this in the past with html-widget was to add a blank
constraint that didn't really do anything, and then if my own code's
check failed, I would do $result->add_error() before redisplaying the
form.
FormFu doesn't support add_error(), but you should be able to get the
same result with $constraint->force_errors(1)
