I've noticed that if I use the numericality validator and the user
enters, for example "1234ABCD" it'll come back with a "not a number"
error, but it then fills the input box with "1234", discarding the non-
numeric input the user originally put in.
I've seen a similar question about this in this group, but the poster
was looking for a way to completely blank the number upon return. I
want something different - I'd like the original value to be
displayed, which seems more logical to me.
What worries me about having it auto-strip the non-numeric stuff is,
if a user has a couple of validation problems in the form, they may
fix other ones, not noticing the numeric, which will now happily post
because it's been turned into a number automagically by Rails - and
maybe not the number that was intended.
I'm afraid it may be impossible since I think it's actually the input
parser doing this and not the validator, but does anyone know how to
make the original value come back instead of the parsed?
Thanks in advance.
