Rails - Dec 2005 - text_field_with_auto_complete and record ID

I understand it''s not possible to retreive the ID of a record selected
using
text_field_with_auto_complete, but I''m struggling to create my own
version
of the helper with that functionaility.

has anyone managed to do this? if someone has a code sample, I''d be
very
grateful

What I did is in the action that does the retrieval, I set the LI's ID
attribute to the record ID.  Then, I have an afterUpdate callback that
copies the ID in a hidden field.

Something like this:

app/views/products/_form.rhtml:
<%= hidden_field :product, :supplier_id %>
<%= text_field :supplier, :name, :size => 40, :value =>
@product.supplier.nil? ? nil : @product.supplier.display_name %>
<br/><%= link_to 'New supplier', {:icon =>
'user_add', :controller =>
'/admin/parties', :action => :new}, {:target => '_new'}
%>
<div class="auto_complete"
id="supplier_name_auto_complete"/>
<script type="text/javascript">
  new Ajax.Autocompleter('supplier_name',
'supplier_name_auto_complete',
       
'/admin/product_catalog/products/auto_complete_for_supplier_name',
        {afterUpdateElement: function(element, selectedElement) {
            $('product_supplier_id').value
selectedElement.id.substring(1);}});</script>

app/views/products/auto_complete_for_supplier_name.rhtml:
<ul>
<%= render :partial => 'supplier', :collection => @suppliers
%>
</ul>

app/views/products/_supplier.rhtml:
<li id="s<%= supplier.id %>"><%=
h(supplier.display_name) %></li>

This was built on Rails 0.12 originally, and hasn't changed since.  It
should probably be revisited to use more helpers.

Bye !

Has anyone ever rewritten this, using "text_field_with_auto_complete"?

I am struggling with it, but can''t get it to work. I can retrieve a 
String, but not the ID. Help, anyone?

If I remember correctly, auto_complete_field now has support for
afterUpdateElement.  Look in the code:
http://dev.rubyonrails.org/browser/trunk/actionpack/lib/action_view/helpers/java_script_macros_helper.rb#L146
