Ext.define('app.store.Reviews', {
    extend: 'Ext.data.Store',
    model: 'app.model.Review',
    pageSize: 200,
    remoteSort: true,
    // allow the grid to interact with the paging scroller by buffering
    buffered: true,
    proxy: {
        type: 'ajax',
        url: 'review/list',
        reader: {
            type: 'array',
            root: 'list',
            totalProperty: 'count'
        },
        filterParam: 'query'
    },
    listeners: {
        load: function (store,records,successful,eOpts) {
            //older
            console.log(store.proxy.reader.jsonData);
            //4.2
            console.log(store.getProxy().getReader().jsonData);
        }
    }
