Records: I can't access response object after a failed save method

[pret]

Hi all,

Recently I've posted this question, and I thought I had the answer, but there's a problem. I need to access the response object in the "success" and "failure" callbacks of the "save" method of a record:

myRecord.save({
    success:                 function(record, operation) {
        var response = operation.response;    // OK, here I have the response
    },
    failure:                   function(record, operation) {
        var response = operation.response     // ERROR. operation doesn't have the response!
    }
})

This is a problem for me, because I need to access additional data from the response I send back from the server:

{success: false, errors: [{error: 'Error1'}, {error: 'Error 2'}], msg: 'There were errors', additionalParameters: [{param1: 'Param 1'}]}

Thanks in advance.

The save method only accepts a config object of Ext.data.Operation which only has a callback function.

Hi!

Strange, the callbacks defined in "success" and "failure" are called too. Defining "callback" with my callback still receives an Ext.data.Operation object with no "response" object, which is what I need.

This is what I'm receiving in a failure case (from Chrome's console):

Ext.Class.newClass
action: "update"
callback: function (record, operation, success) {
error: undefined
exception: true
records: Array[1]
request: Ext.Class.newClass
running: false
scope: Ext.Class.newClass
success: false
__proto__: Class.registerPreprocessor.prototype

However, if I change the name of the property "callback" and I use "success", in a success case the response IS defined:

Ext.Class.newClass
action: "update"
complete: true
records: Array[1]
request: Ext.Class.newClass
response: Object             -> This is what I need
resultSet: Ext.Class.newClass
running: false
scope: Ext.Class.newClass
success: true
__proto__: Class.registerPreprocessor.prototype

Thanks!

Do you have access to the proxy/reader from the callback maybe from the 'this' scope? You can get the data there then.

Great! That's the way to find the response. I finally access the response in the following way:

record.save({                
    callback:        function(record, operation, success) {
        var response = this.getProxy().reader.jsonData;
    }
});

I really think this should be part of the operation object. It's too hidden this way.



Thanks a lot for your help!

Sorry, but I don't understand how it works for you?
reader.jsonData
contains, in my case, entire data loaded so far to the store, but I need access to response object.
And later on to response.responseText. I handle entire batch of operations, so I actually need that for every operation in a batch, that failed.
How to get reference to response object for each operation, and WHY it is not included by default?!

on success I can assess that in the following way:
batch.operations[0].response.responseText

"response" in undefined in case of failure

EDIT: I have finally found rather ackward way of accessing response object in callback arguments!
operation.request.callback.arguments[2]

EDIT2: the path provided above only works for the last operation in batch.
