Getting error message from Store Proxy

I would like to get an error message from a store proxy call.

My store looks like this :

Ext.define("MyStore", {
    extend: "Ext.data.Store",
    model: 'mymodel',
    proxy: {
        type: 'customrest',
        paramsAsJson: true,
        url: myUrl,
        actionMethods: {
            read: 'POST'
        },
        reader: {
            type: 'json',
            record: 'result',
            root: 'results'
        }
    },

    listeners: {
        load: function (store, records, success) {
            if (!success) {

            }else {
                //OK
        }
        }
    }
});

It seems to only give me success is false, and no other information is at hand. I know there is also an error message coming back because the data coming back looks like this :

{success: false, message: "blah blah blah“"}

is there somewhere I can get a handle on 'message'?

UPDATE :

My store is called like this :

this.psstore = Ext.getStore("MyStore"); 

this.psstore.load({
    params: postBody,
    callback: function (records, operation, success) {

        if (success) {
Solution

  • Check out your reader's messageProperty:

    http://docs.sencha.com/extjs/4.0.7/#!/api/Ext.data.reader.Json-cfg-messageProperty

    so in your config you should have: 

        reader: {
        type: 'json',
        record: 'result',
        root: 'results',
        messageProperty: 'message'
    }

    You should then be able to get the message through the operation.exception property (IIRC) in the load callback. It's also a parameter passed in the onLoad event (http://docs.sencha.com/extjs/4.0.7/#!/api/Ext.data.Store-event-load), so you should also be able to access it there. We're using that on Ext 4 with an XML reader and in our upgrade to 6 so it's safe to use.
