    Default Passing store data to server side

    Passing store data to server side


    Hi there,

    I have a grid whose store definition is as follows

    Code:
    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?

    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?

    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.
    Code:
    // 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.
