Hi there,
I''m trying to validate a field in my form to make sure that it is a
single
word (i.e. no spaces). This word may however contain german characters.
I have in my model:
validates_format_of :name,
:with => %r{\w+},
:message => "cannot contain special characters or spaces"
but this lets anything through. I freely admit that I''m a reexp
beginner,
infact ''beginnner'' may be self-flattery.
Would appreciate any advice/help

Thanks for the reply Ludde. The regexp works now on english characters but won''t accept german characters (äöüß). Any ideas? Does /^\w+$/ work on all swedish characters?

I would probably solve the problem by using a bracket expression listing all acceptable characters: /^[A-Za-zÄÖÜäöüß]+$/ /ludde> Regards > > Adam > > On Tue, Nov 29, 2005 at 01:30:08PM +0100, Adam Groves wrote: > > Hi there, > > > > I''m trying to validate a field in my form to make sure that it is a single > > word (i.e. no spaces).
