How to configure ExtJS 4 Store (proxy and reader) to read metadata

Question

My question is how to get metadata besides totalRecords, in my case it is version, code, searchquery (please look at json).

{
\"result\": {
    \"version\":\"1\         


        

Answer 1

Here is solution for my problem. I am handling afterRequest event in the Proxy class where I can get response data, parse it and save metadata. This is proxy part of the TestStore class:

So here is proxy part from the TestStore class:

proxy: {
        type: "ajax",
        url: "/users.json",  
        reader: {
            type    : 'json',
            root    : 'gip.account',
            totalProperty: "gip.totalRecords",
            searchquery: "searchquery"
        },
        afterRequest: function(req, res) {
            console.log("Ahoy!", req.operation.response);    
        }
    }
