Re: Django session and Dojo dnd.

Hi,

i haven't tested the code and never used dojo before, but sth. like
this should work:

var source1 = new dojo.dnd.Source("itemListNode");
var source2 = new dojo.dnd.Target("selectedListNode");
dojo.connect( source1, "onDndDrop",
function(source, nodes, copy, target){
//gather items and details
var details = [];
for( i=0; i < nodes.length; i++){
var item = this.getItem(nodes[i].id);
details.push(item.data);
}
//send details to server via AJAX POST request
dojo.xhrPost({
url: "/save_details/",
content: {details: JSON.stringify(details)},
// The success handler
load: function(response) {
alert('ok');
},
// The error handler
error: function() {
alert("error");
}
});
});

Explanation:

- changed 'item' to 'var item' ... without the 'var' item will be
global, which is probably not what you want.
- to get around making multiple requests to the server(one for each
dropped node), put the detail of each node in the details array.
- then json-encode and send this array to your django view (assumed to
be at '/save_details/')
- in the view, access the list as
json.loads(request.POST.get('details', '[]')) and place it into
request.session

As mentioned, the code is completely untested.

Good luck!

Yours,
