i use this code to validate the phone field.it should have only numbers. but it also accepts alphapets with numbers.it should not accept other than numkbers below is my code i use. errors.add(:phone_code, "*please enter valid phone number") unless self.phone_code =~/[0-9]/
That will match if there is at least one number in the string. I think you need something like /\A[0-9]*\z/ or /\A\d*\z/
or possibly even better you could use something like validates_numericality_of :phone_code, :only_integer => true, :greater_than => 0 Though I think this would allow a leading + character.
