Rails - May 2007 - update_element_function + sortable_element = how to update ?

Hi.

I''ve realised this example and it works great :
http://demo.script.aculo.us/ajax/sortable_elements

But i want to add to the user the capability to add items to the
sortable list.

Here is my code :

#######################
#list_controller.rb :
#######################

class ListController < ApplicationController
  def index
    @elements = ["toto", "titi", "tata",
"riri", "fifi", "loulou"]
  end

  def order
    @order = params[:list]
    render :partial => ''list''
  end
end

#######################
#index.rhtml :
#######################

<div id="choix_elements">
<% i = 7 %>
    <% @elements.each do |elt| %>
        <span id="<%= elt %>"
onclick="<%update_element_function(''list'', :position
=> :bottom, :content => "<li
id=''item_#{i}''>#{elt}</li>") %>">
            <%= elt %>
        </span>
        <% i += 1 %>
    <% end %>
</div>

<ul id="list">
  <% 6.times do |i| -%>
  <li id="item_<%= i+1 %>">I''m number <%= i+1
%></li>
  <% end -%>
</ul>

<p id="list-info"></p>

<%= sortable_element ''list'',
      :update => ''list-info'',
      :complete => visual_effect(:highlight, ''list''),
      :url => { :action => "order" } %>

#######################
#_list.rhtml
#######################

Updated order is: <%= @order.join('', '') %>.



The trouble is that added elements couldn''t be sorted. Is there a way
to
"refresh" the sortable_element method please ?

Thanks in advance.

What I would do is on your index.rhtml page, add a remote_form_for
that takes in a new element and submits it to a "add_element" action
in your controller. The, via an RJS file or just inline in the
controller (via render :update) I''d replace_html on the dom element
that holds your list.
