Sending extra parameters when saving a model instance (on record.save())

[Spenna]

Hi there.
I need to send some extra parameters to the server when updating/creating a record/model, but can't figure out how. Something like this:

// Show form etc.. 
var form = new Ext.form.Panel();
var record = new Model();
form.loadRecord(record);
form.show();

Then when some imaginary button is clicked

var record = form.getRecord();
record.set(form.getValues());

record.save({
    extraParams : { // this is what i want to do, to send additional parameters
        param1 : 'some value',
        param2 : 'some other value'
    },
    success : function(record) {
        // all good
    }
})

I've searched the forums and api, but only way i've managed to do it is to add extra fields to my model, which I don't want, since its used elsewhere.

edit: just took a look at the sources. try out

record.save({params:{foo:'bar'}});

in my case it will not work...

record.save({params:{foo:'bar'}});

This kindof does the job, but the params are always added to the querystring even though request method is not GET.
In my scenario i'm using a RESTful store, so it would be nice if params added could be sent in the same manner default params are (GET, POST, PUT, DELETE)

if you like to, i can move the topic to the bugreport forums.

You could do that, even though i'm not so sure its a bug, but rather limitations of the current http-protocol - especially in terms of the DELETE request where its not safe to send a body with the request: (http://stackoverflow.com/questions/2...delete-request)
It would still be nice to hear what the developers has to say on the topic.

Essentially, what i need to do is to send some meta information when i update or delete a model instance. For example i want the end user to specify a reason for deleting. For now i've reverted to doing a form post and manually reloading the store at need. Kind of hackish. Thanks for your input though!

i overwrite writeRecords to have the functionality:

            writeRecords: function(request, data) {
                var root = this.root;

                Ext.applyIf(data[0], request.params || {});

                if (this.allowSingle && data.length == 1) {
                    // convert to single object format
                    data = data[0];
                }

                if (this.encode) {
                    if (root) {
                        // sending as a param, need to encode
                        request.params[root] = Ext.encode(data);
                    } else {
                        //<debug>
                        Ext.Error.raise('Must specify a root when using encode');
                        //</debug>
                    }
                } else {
                    // send as jsonData
                    request.jsonData = request.jsonData || {};
                    if (root) {
                        request.jsonData[root] = data;
                    } else {
                        request.jsonData = data;
                    }
                }
                return request;
            }

I tested your override, but it still just gets appended to the querystring (as in GET).

[Dumbledore]

Did you use extraParams or params? When using my override you must use it like:

record.save({params:{foo:'bar'}});

[Spenna]

I use params as specified, but its always appended to querystring regardless of http method
