Phone format in Rails

Guys,

     I have a text field and the name is phone
    I used to enter contact number.
   In the new form when i enter 10 digit number like "1234567890" it
is displaying 1234567890
  I want to display like in US format automatically like "(123)
456-7890".
   I need to provide validation for that field also.
Can u help me how can i do that.
  Very badly i need a help. i am struck with this issue......

validates_format_of :phone, :with => ((\(\d{3}\) ?)|(\d{3}[-
\.]))?\d{3}[- \.]\d{4}(\s(x\d+)?){0,1}$

you could simply write your own helper like that:

  def format_phone_number(number)
    return "(#{number[0..2]})#{number[3..5]}-{number[6..-1]}"
  end

add it to your view_helper and call it whenever you like.

validations are similar. just add your own validation.

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

Sorry, made a mistake, the result of number_to_phone would be (123)
456-7890 (I missed the 0).

And about the number of digits, I said \d{10} makes sure the string
contains only 10 digits. What I meant is that the string will have to
contain a total of 10 digits, no more, no less.
