save you have a
db.define_table('item',
Field('number','integer'),
Field('name'),
Field('link'))
and you want to make a view with ajax sortable links like:
<ul id="sortable">
{{for i,row in enumerate(db().select
(db.item.ALL,orderby=db.item.number):}}
<li id="{{=row.id}}_item" class="sortable_item">
{{=A(row.name,_href=row.link)}}
</li>
{{pass}}
</ul>
No make them sortable you need:
1) The script below:
<script src="{{=URL
(request.application,'static','jquery.dimensions.js')}}"></script>
<script src="{{=URL(request.application,'static','ui.mouse.js')}}"></
script>
<script src="{{=URL
(request.application,'static','ui.draggable.js')}}"></script>
<script src="{{=URL
(request.application,'static','ui.droppable.js')}}"></script>
<script src="{{=URL(request.application,'static','sortable.js')}}"></
script>
<script>
function sortUpdate(a,b)
{
var dragEls = jQuery
(".sortable_item");
var els =
'';
jQuery.each(dragEls, function ()
{
var cur_id = jQuery(this).attr('id').split('_').shift
();
els += cur_id
+",";
});
var url = '{{=URL(r=request,f='sort')}}?order='
+els;
jQuery.get
(url);
}
jQuery(document).ready(function()
{
jQuery("#sortable").sortable({stop:
sortUpdate });
});
</script>
2) the following callback action:
def sort():
for i,id in enumerate(request.vars.order.split(',')[:-1]):
db(db.item.id==id).update(number=i)
return 'done'
that is all.
perhaps somebody could make a plugin about this.
