Rails - Oct 2009 - Multi Select with fields_for

I''m trying to get a multi select box working with fields_for but am
having a
few problems.

My view has ....

<% form_for(@teacher) do |f| %>
  <%= f.label :surname %>
  <%= f.text_field :surname %>

  <% f.fields_for :qualifications do |qual_form| %>
    Qualifications:  <%= qual_form.select( :id, @qualifications) %>
  <% end %>

  <%= f.submit %>
<% end %>

Which produces (for the fields_for) ......

<select id="teacher_qualifications_attributes_0_id"
name="teacher[qualifications_attributes][0][id]">
  <option value="5">Licence</option>
  <option value="1">NPLQ</option>
  <option value="3">Teacher''s Level One</option>
  <option value="4">Teacher''s Level Two</option>
  <option value="2">Teacher''s Rescue
Test</option>
</select>

and on submission I have  ......

"teacher"=>{"qualifications_attributes"=>{"0"=>{"id"=>"2"}},
"surname"=>""}}

but what I think I really want is a multi select box with the submitted data
looking something like ......
"teacher"=>{"qualifications_attributes"=>{"id"=>["2","3","4"]}},
"surname"=>""}}

Could somebody putme out of my misery, please?

TIA

Do you know how to make a multiple select in HTML?  You just use <select 
multiple="multiple">.  So in Rails, you''d put :multiple
=> true in the
html_options for your select helper.  Simple.
