Hello Michael,

Michael Roper said the following on 2005-09-26 01:46:

Yes, exactly.  You can get the latest version at
http://dev.rubyonrails.com/browser/spinoffs/scriptaculous/

Sure, no problem.

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 %>
<div class="auto_complete"
id="supplier_name_auto_complete"/>
<script type="text/javascript">
   new Ajax.Autocompleter(''supplier_name'',
''supplier_name_auto_complete'',
     ''/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>

app/controllers/products_controller.rb:

def auto_complete_for_supplier_name
   name = "%#{params[:supplier][:name].downcase}%"
   conditions = []
   values = []
   conditions << ''destroyed_at is null''
   conditions << ''supplier = 1''
   conditions << ''(company_name LIKE ? OR last_name LIKE ? OR
first_name
LIKE ?)''
   3.times { values << name }
   @suppliers = Party.find(:all, :limit => 15,
       :conditions => [conditions.join('' AND ''),
values].flatten.compact,
       :order => %q(CONCAT_WS('' '', company_name, last_name,
first_name)))

   render :layout => false
end

As you can see, in my _form, I manually created the auto complete magic
that Rails usually does for me.  I can''t remember anymore, but I think
there was no way for me to send the afterUpdateElement option to the
Ajax.Autocompleter.

I hope that helps !
