sortable_element - issue with passing parameter with the method called from the :url => :action

Is it possible to pass a parameter with the method call attached to
the :action of sortable_element? I've put together the code below
which doesn't work but it demonstrates the desired behavior.

# in the view (well, in the helper really but in a method that's
called from the view).
    container_ids_containing_items.each do |container_id|
      output += sortable_element(
        ["items_contained_by_container_id_", container_id].join,
        :constraint => false,
        :handle => "gearItemValueTitle",
        :containment => container_ids_containing_items.map { |n|
["items_contained_by_container_id_", n].join},
        :scroll => "window",
        :url => {:action =>
"update_contained_items_positions(\"#{container_id}\")"})

# in the controller
  def update_contained_items_positions(container_id)
    # ... - perform save
  end

just noticed an issue with the quoting of the paramter. I've fixed it
but it still doesn't work, here is the updated sample:

    container_ids_containing_items.each do |container_id|
      output += sortable_element(
        ["items_contained_by_container_id_", container_id].join,
        :constraint => false,
        :handle => "gearItemValueTitle",
        :containment => container_ids_containing_items.map { |n|
["items_contained_by_container_id_", n].join},
        :scroll => "window",
        :url => {:action =>
"update_contained_items_positions(#{container_id})"}) # <---- made
change to the quoting of container_id

Maddy,

Instead of passing a parameter like that in the action, pass it as a
separate has value. I.e.:

:url => {:action => "update_contained_items_positions", :id =>
container_id }

Then, in the controller action, just use params[:id] to reference the
id.

I don't know that action methods can include arguments as I don't know
how the routing would handle that.

See if that helps.
