converting retrieved models

Hi and good morning, dear friends.

After a long time I did continue developing my project. First step was, to upgrade to JMVC 3.3 due to the fact, that canJS seems to be very tidy.

I have a problem no with converting my models. My service with php-backend delivers the data like this:

1. {"result":{"loggedin":false},"id":"100","jsonrpc":"2.0"}

where

1. {"loggedin":false}

is the data. The scaffold around it, is always the same.

The Ajax requests fires not directly by the Model but by a ServiceLayer. I want to be able to change the method by editing only one place.

iuristico/models/model_service_layer.js:


1. steal('can', function (can) {
2.     return can.Model(
3.     /* @static */
4.     {
5.                 sequence : 100,
6.                 model: function( attributes ) {
7.                               steal.dev.log('model function is fired')
8.                               return this._super(attributes.result);
9.                             },
10.                 models: function( instancesRawData ) {
11.                               this._super(instancesRawData);
12.                             else return this._super(instancesRawData.result);
13.                             },
14.                 queryfunc : function(id, method, params, success, error){
15.                     steal.dev.log(this.shortName, this)
16.                     var modeltype
17.                     if(method == 'findAll')  modeltype = 'models'
18.                     else modeltype = 'model'
19.                     var returninstance = this.shortName.substr(0, 1).toLowerCase() + this.shortName.substr(1)
20.                     steal.dev.log('returninstance',returninstance)
21.                     return $.ajax({
22.                                 async: true,
23.                                 contentType: 'application/json',
24.                                 type: 'POST',
25.                                 processData: false,
26. //                                dataType: 'json '+returninstance+'.'+modeltype,
27.                                 dataType: 'json',
28.                                 url: '/api/v1/jsonrpc.php',
29.                                 cache: false,
30.                                 success: function(data){steal.dev.log('success', data)},
31.                                 error: function(){steal.dev.log('error')},
32.                                 complete: function(){steal.dev.log('ModelServiceLayer always')},
33.                                 data: JSON.stringify({jsonrpc : '2.0', method :method, params : new Array(returninstance, params) , id : (this.sequence++)}),
34.                                 headers: {}
35.                                     })
36.                    
37.                 },
38.         findOne : function(params, success, error){
39.                     return this.queryfunc(null, 'findOne', params, success, error)
40.                 },
41.     },
42.     /* @Prototype */
43.     {});
44. });

the line


1. dataType: 'json '+returninstance+'.'+modeltype

did work in the old version but produces an en arror now.

the model looks like

login.js:


1. steal('iuristico/models/model_service_layer.js', function (modelServiceLayer) {
    return modelServiceLayer.extend('auth',
    /* @static */
    {
    },
    /* @Prototype */
    {});
});

it is invoked by

1. this.list.replace(Login.findOne());
   

in the controller.

everything works fine but the result of the steal.dev.log on success is

1. { result={loggedin = false}, id="100", jsonrpc="2.0"}

instead of

1. { loggedin=false}

what am I doing wrong?
