Multi Select and Virtual Attributes

Using Rails 2, I have multiple objects in a form and am using
fields_for. My
problem is creating a multi select and sending that off to the
controller as
a hash.

In my erb, I have …

<% teacher.fields_for :qualifications do |qual_form| %>
<%= [], @qualifications, { :multiple => true, :size
5, :disabled => false } %>

which produces a non-multi select …

Licence NPLQ Teacher's Level One Teacher's Level Two Teacher's Rescue Test

which sends “qualifications”=>[“5”] to the controller and not
qualifications"=> { [“5”] }

The HTML produced looks almost right but isn’t. I can send a hash of
information with a <%= qual_form.text_field :id %> for example but I
need a

I’ve tried select_tag and although I’m able to get a multi select going
I still can’t send a hash.

<%= select_tag “teacher[qualifications][]”, options_for_select(
@qualifications, @selected_qualifications ),
{ :multiple => true, :size => 5, :disabled => false,
=> “qualifications” } %>

Can someone help me, please.

Thank you
