Hi Guys,

validates_numericality_of :phonefiled

Well, phone "numbers" are almost never numbers. You might have "(02) 9876 5432" or "+61 2 9876 5432". Best to validate against a regexp, e.g.:

phone_number =~ /[0-9() +]+/

There are options you should check out at api.rubyonrails.org

Yes, their examples even have phone number validation:

+1 for Regex.

You never know when a user will input any of these valid phone numbers versions

(404) 555 1212 404 555-1212 4045551212 etc…
