    Default Answered: POSTing deeply nested XML/JSON data

    Hi all,

    I have a client side data object which looks like this one created after processing a form with some logic:

    Code:
    requestObj =
                    {
                            firstName: "John",
                            lastName : "Doe",
                addresses : [
                                {
                        address: {
                            houseNo : "42", 
                                            street : "abc",
                                            area: "def", 
                                            city: "ghi",
                                            country: "jkl"
                        }
                }    
                ]    
                    };

    I, then, package this object into a model instance created from this model definition:

    Code:
    Ext.define('personalInfo', {
        extend : 'Ext.data.Model',
        config : {
            fields : [
                {name : 'firstName'} ,
                {name : 'lastName'} ,
            ],
            hasMany : [
                {model : 'address', name : 'adresses', associationKey : 'addresses'},
            ]
        }
    });
    
    
    Ext.define('address', {
        extend : 'Ext.data.Model',
        config : {
            fields : [
                    'houseNo', 
                    'street',
                    'area',
                    'city',
                    'country',
            ]
        }
    });
    
    requestModelInstance = new personalInfo(requestObj);
    After this I am binding this with a store which has a proxy and writer configured to make a POST request to my server.



    Code:
    
    var personalInfoUpdateRequest = new Ext.data.Store({
        model : 'personalInfo',
            proxy : {
                    type : 'ajax',
                    url : 'serviceURL',
            headers: { 'Content-Type': 'application/json' },
                    writer : {
                        type : 'json',
                        encode : true,
                        rootProperty : 'personalInfo',
                    }
            }
    });
    
    
    personalInfoUpdateRequest.sync(); // To make the POST

    The POST request is going but the fields I see are only the top level ones, i.e., firstName and lastName. There is no trace of the 'addresses' array. I have tried both XML and JSON infact there seems to be some issue with the requestObj getting packaged into the requestModelInstance.

    There is, practically, no example anywhere in the docs which helps in doing something like this.

    Please help!

  2. Syncing associated data is not yet supported. You could iterate through the records and associations to build your data structure to send.
