Store Sync Response

[tomearly]

Hi,

I have a Ext.data.Store on which I doing a sync.

My sync works ok and I return some JSON. I can see the response in Firebug, but how do I use the response JSON?

I've looked at the examples, looked through the forum and the internet, but cannot see how to do this.

Below is the code I use for my store. If anyone is interested, i'm using the Bryntum Scheduler.

eventStore : Ext.create("Ext.data.Store", {
                                idProperty : 'Id',
                                model : 'Sch.model.Event2',
                                autoLoad: true,
                                proxy: {
                                       type: 'ajax',
                                       api: {
                                            create: '/cgi-bin/EV_Rostering_Shifts_Save_New.pl', // Called when saving new records
                                            read: '/cgi-bin/EV_Rostering_Events_Get.pl?branch=' + branch + '&view=' + view,
                                            update: '/cgi-bin/EV_Rostering_Shifts_Save_Update.pl', // Called when updating existing records
                                            destroy: 'myBackend.php?action=destroy' // Called when deleting existing records
                                       },
                                       reader: {
                                                type: 'json',
                                                model : 'Sch.model.Event2'
                                       },
                                       writer: new Ext.data.JsonWriter({
                                                encode:         true,
                                                writeAllFields: true,
                                                root: 'data'
                                       }),
                                       timeout: 10000
                                },
                                listeners: {
                                        //add
                                        add: function(store, records, index, options)
                                        {
                                        },
                                        update: function(store, records, index, options)
                                        {
                                        }
                                        //remove
                                        //update
                                }
                            }),

Take a look at the store.write event for successfull update, for errors there is the proxy exception event.

Hi,

Thank you for the reply. Yes this is good for knowing if it was successful and is partly what I need.

When I have done the sync, I return some JSON from the script that processes the sync data.

I want to be able to use this data to

1) determine a success or failure ( and a reason )
2) to be able to return data to update the store ( this will contain IDs that are generated but the DB )

Any ideas how I can do this?

Thanks,

Tom

I've worked it out.

I've added an exception listener to the store and can then access the response upon syncing the store.

Something like this:-

eventStore : Ext.create("Ext.data.Store", {
                                idProperty : 'Id',
                                model : 'Sch.model.Event2',
                                autoLoad: true,
                                proxy: {
                                       type: 'ajax',
                                       api: {
                                            create: '/cgi-bin/EV_Rostering_Shifts_Save_New.pl', // Called when saving new records
                                            read: '/cgi-bin/EV_Rostering_Events_Get.pl?branch=' + branch + '&view=' + view,
                                            update: '/cgi-bin/EV_Rostering_Shifts_Save_Update.pl', // Called when updating existing records
                                            destroy: 'myBackend.php?action=destroy' // Called when deleting existing records
                                       },
                                       reader: {
                                                type: 'json',
                                                model : 'Sch.model.Event2'
                                       },
                                       writer: new Ext.data.JsonWriter({
                                                encode:         true,
                                                writeAllFields: true,
                                                root: 'data'
                                       }),
                                       timeout: 10000,
                                        listeners: {
                                                exception: function(proxy, res) {
                                                        //console.log(proxy);
                                                        //console.log(type);
                                                        var responseObj = Ext.JSON.decode(res.responseText);
                                                        var success = responseObj.success;

                                                        if(success == true)
                                                        {
                                                                EV.Rostering.Grid.eventStore.commitChanges();
                                                                EV.Rostering.Grid.eventStore.load();
                                                        }
                                                        else
                                                        {
                                                                alert('Unable to save shift(s)');
                                                        }
                                                }
                                        }
                                }
