dataStore response after sending to server (store.save)

[stefanosandes]

Hello!

I have a code that sends data from one grid to the server.
Everything works fine, but do not know how to get the server response.

Can you help me?
Thanks!

var writer = new Ext.data.JsonWriter({
        encode: true

    });

    var Cr = Ext.data.Record.create([
        { name: 'DE_CD_UNIDADE' },
        { name: 'VL_PRECO' },
        { name: 'VL_DECORACAO' }

    ]);

    var reader = new Ext.data.JsonReader(
        {
            root: 'data',
            messageProperty: 'message'
        }, Cr
        );

    var proxy = new Ext.data.HttpProxy({
        api: {
            create: '_CODE/ASPX/_tabvendas/_tab_venda_importacao.aspx'
        }
    });

    var dsTabVendaImportacao = new Ext.data.Store({
        proxy: proxy,
        reader: reader,
        writer: writer,
        autoLoad: false,
        autoSave: false,
        baseParams: { cdEmpreendimento: cdEmpreendimento, cdBloco: cdBloco, cdTabela: cdTabela },
        listeners: { 'add': function () {
            if (this.getCount() > 0) {
                Ext.getCmp('btnSalvar').enable();
            } else {
                Ext.getCmp('btnSalvar').disable();
            }
        }
        }
    });

    Win = new Ext.Window({
        title: Tit
        , width: 450
        , height: 220
        , layout: 'fit'

        }
    }).show();

Hi,

Listen to the 'write' event of the store.

[stefanosandes]

I tried using the event "write", but not passed by the event.

I used:

listeners: ('write': function ()
{
        alert ('hello')
}
} 

Did not work.

[plalx]

When listening to the Ext.data.Store's write event, the data param will contain the content of the 'data' property of the object created from the server response. If you want to retrive the whole data returned by the server, I think you have to listen to the write event of the Ext.data.DataProxy encapsulated in the store.

E.g.

store.proxy.on('write', function(store, action, data, response) {
   console.log(response);
 });

scarsick,

I tested your solution, but without success.

It may be some problem in json format of my reply?
The server returns: '{success: true}'.

Thanks!

[stefanosandes]

The event 'exception' is called, but 'write' no.

Firebug by the server is returning 200.
The code on the server side is perfect.

Any solution?
I am using Asp.net.

[plalx]

Well, if the exception event is called, write event won't be called, obviously hehe. If the server returns 200 and exception event is fired, it means that the store reader did not succeed in parsing the value returned by the server.
Log the 'arg' argument passed to the exception event handler function, it should be a javascript Error object. You will then be able to see why the parse failed. But before doing this, I suggest that you add message: "" to your json response, I think it is mandatory to have it.

exception : ( DataProxy this, String type, String action, Object options, Object response, Mixed arg )

E.g. server response:

 
{ "success": true, "message": "" }

[stefanosandes]

Well, if the exception event is called, write event won't be called, obviously hehe

Sorry, my English is not good. hehe.

There is no error by the server or the formed JSON returned, sure.

I managed to get the response from the server within the "exception". From what I understand, for the event to "write" sech called I have to return the data that was sent from my datastore. In this example: http://dev.sencha.com/deploy/dev/exa...l/restful.html

Thanks for your help!
