I'm not sure the type of validation you need on the field. This is
something simple I did for an application I wrote:
phone =~ /^\d{10}$/ && phone.to_i >= 999999999
This will make sure that the string contains only 10 digits (/^\d
{10}$/) and that the 10 digits are miningful or the number doesn't
start with a 0 (>= 999999999).
About the formatting of the string, rails has tons of helpers, and the
one you're looking for is number_to_phone:
<%= number_to_phone(1234567890, :aea_code => true, :delimiter => ' ')
%> # (123) 456-789
