Rails - Mar 2007 - draggable_element: How to get id of dragged element, AND receiving element?

Hey :)

I''m creating a drag-and-drop tree structure using draggable_element. I
use this code,

  <%draggable_element(content_element_id, :ghosting=>true,
:revert=>true)
%>

  <%= drop_receiving_element(content_element_id,
                            :accept     => ''tree_item'',
                            :complete   => "$
(''#{content_element_id}_activity_indicator'').hide();",
                            :before     => "$
(''#{content_element_id}_activity_indicator'').show();",
                            :hoverclass => ''hovering'',
                            :with       =>
"''child_id='' +
encodeURIComponent(element.id.split(''_'').last())",
                            :url        => { :action => :adopt } ) %>

This way, I can send the id of the element that is being dragged, to
the :adopt action in my controller. But I need to know which element
the dragged element was dropped upon, so it can be adopted by the
right parent.

Anybody know how I can do that?

Thanks in advance,
Daniel :)

Ah, silly me :)

Just have to add it to the drop_receiving_element call in :url!

                            :url        => { :action
=> :adopt, :parent_id => navigation_point.id } )%>

Cheers :)
