Rails - Mar 2006 - Radio Button Defailt Value?

I have:

<%= radio_button ''foo'', ''bar_id'',
''1'' %>
<%= radio_button ''foo'', ''bar_id'',
''2'' %>
<%= radio_button ''foo'', ''bar_id'',
''3'' %>

I would like to have option #3 be selected if foo.bar_id is nil. Is 
there a way to do that?

In your controller, do

@foo.bar_id = 3

or

@foo.bar = Bar.find(3)
