Passing store data to server side

[harjits]

Hi there,

I have a grid whose store definition is as follows

this.store = new Ext.data.JsonStore({
        autoload : false,
        idProperty : 'groupID',
        root : 'Name_report',
        totalProperty : 'count',
        successProperty : 'success',
        messageProperty : "msg",
        autoScroll:true,
        fields : [
            {
                name : 'entityID'
            },{
            name : 'groupID'
        }, {
            name : 'groupName'
        }, {
            name : 'originalName'
        }, {
            name : 'standardName'
        }
        ],
        remoteSort : false,
        proxy : new Ext.data.HttpProxy({
            url : QUERY_URL +"?type=NAME",
            defaultHeaders : {
                Accept : 'application/json'
            },
            method : 'post',
            disableCaching : false
        })
    });

I want to send the json representation of the store data to the server for generating reports. Is there any way I can do that ?

I'm not sure I understand what you want to send to the server?

Can you give an example of what you expect to send?

[harjits]

I need to pass the data contained in the store

[willigogs]

You need to pass the entire dataset held in the store? I'm not sure why you would need to do that - since it must already be populated by a call to a DB anyway?

Why are you wanting to send every record?

[harjits]

That's what I need to know, how can I pass the entire data set. I can't query the DB again because in sme cases the query takes time to fetch the results and hence I don't want to query the DB again to fetch the data. Hence I need to pass the data which is contained in the store as JSON or some other format to the server to generate PDF.

Yes, this is possible.

// GRAB THE DATA OBJECT
var data = store.reader.jsonData;
// CONVERT TO JSON STRING
var str = Ext.util.JSON.encode(data.Name_report);

Then simply pass the str variable during your call to create the report.

That worked thanks....
