Rails - Sep 2005 - Specify attributes for 'date_select' select inputs

Hi,

I could not find an easy way to specify the ''id'' attribute for
select
inputs of ''date_select'' form helper.

I need to set it because I want to retrieve date selects values from a
javascript.


   <%= date_select ''product'',
''expiration'' %>

generates

   <select name="product[expiration(1i)]">
   [,,]
   <select name="product[expiration(2i)]">
   [,,]
   <select name="product[expiration(3i)]">


I was dreaming something like:

   <%= date_select ''product'',
''expiration'', :id =>
''product_expiration''%>

generating

   <select name="product[expiration(1i)]"
id="product_expiration_day">
   [,,]
   <select name="product[expiration(2i)]"
id="product_expiration_month">
   [,,]
   <select name="product[expiration(3i)]"
id="product_expiration_year">


Any hints?
