I am having a really simple problem with regular expressions and
Rails. I need to validate that input is a number or only digits. I
using this:
validates_format_of :po_box,
:with => /\d*/,
:message => "PO Box must be a number
only. Remove all text."
however, rails is letting anything be entered. i am getting other
regular expressions like /a/ to work but for some reason not \d* or \d
or [0-9]* or [0-9].
Can anyone help?
thanks,
Wes

Okay I found a validation method that works for this: validates_numericality_of ....to answer my own question. However, i still don''t understand why my approach above still doesn''t work???

/^[+\-]?\d+$/ is the expression to check if the format is an integer........

You already answered your question, but for the record, /\d*/ matches zero or more occurrences of numeric digits, so entering anything meets the zero criterion. You can use \d+ which requires at least one digit, but more likely, you want /^\d+$/ which requires everything to be digits and requires an entry.

/^[0-9]+$/ would work as well. -john On Sep 18, 2007, at 4:07 PM, Acroterra wrote:> > /^[+\-]?\d+$/ is the expression to check if the format is an > integer........ > > Wes > > > > On Sep 18, 4:56 pm, Acroterra <acrote...-Re5JQEeQqe8AvxtiuMwx3w@public.gmane.org> wrote: >> Okay I found a validation method that works for this: >> validates_numericality_of ....to answer my own question.
