Rails spinoffs - Jan 2006 - question about sortable demo

Hi,

I''m new to the script.aculo.us library and AJAX. Of course, I already
want to use a sortable list for something more complicated than the
sortable list demo. In the example below, what is the structure of
params[:list]? I don''t know what I can do with it once I have it in my
controller method.

Thanks,
Peter




# view
<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" } %>

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

# _list.rhtml partial
Updated order is: <%= @order.join('', '') %>.

It looks like params[:list] is an array of the numbers in the li id.
Simple as that?

Thanks,
Peter

Hi,

when you declare the id''s of the li elements like

 <li id="entity_2043"></li>
 <li id="entity_2560"></li>
 <li id="entity_2953"></li>

then Sortable.serialize will return the part after the underscore in 
your id attribute in the order the are sorted as an array.
