select_xxx helper and default value

Hi there,

I am struggling with handling the default day/month/year in the select_xxx helper methods. I currently have:

<div id="date_day"><%= select_day(nil, :prefix => "product_return[exchange_date(3i)]", :discard_type => true, :include_blank => true) %></div>

As is, the list will (obviously) always default to the blank selection, but I am hoping for some type of if where if the exchange_date is nil then nil is "used" (as above) and if exchange_date is not níl (there is a date in the db), then exchange_date.day is used.

Any help/ideas would be very much appreciated. If I have missed something really obvious, I apologize.

Thx, -Fredrik Bach fredrikbach@gmail.com
