Ext.data.Operation Read method problem

[jakobgrannas]

Hi,

I am using a method similar to model.load() and when I try to execute that method, the code breaks inside the Ext.data.Operation processRead method. I get an error saying "typeerror: object is not a function" when trying to execute this code (sencha-touch-all-debug.js):

 processRead: function(resultSet) {
        var records = resultSet.getRecords(),
            processedRecords = [],
            Model = this.getModel(),
            ln = records.length,
            i, record;


        for (i = 0; i < ln; i++) {
            record = records[i];
            processedRecords.push(new Model(record.data, record.id, record.node));  <--- Breaks here
        }


        this.setRecords(processedRecords);
        return true;
    },

So for some reason instatiation of Model is not possible. I tried evaluating the expression (new Model) in WebStorm and got the same error message as above ("typeerror: object is not a function")

This is my "load" code and my model:

Ext.define('Intelliplan.Base.Data.Query', {
    extend: 'Ext.data.Model',
    execute: function(params, successHandler, scope) {


        var config = {
            action: 'read',
            params: params,
            model: this
        };


        var operation = Ext.create('Ext.data.Operation', config),
        proxy = this.getProxy(),
        record = null,
        callback;


        callback = function(operation) {
            if (operation.wasSuccessful()) {
                var result;
                if(proxy.dataType === 'list'){
                    result = operation.getRecords();
                }else{
                    result = operation.getRecords()[0];
                }
                Ext.callback(successHandler, scope, [result, operation]);
            }else{
                
            }
            /*  TODO implement handlers for other than success {
                Ext.callback(config.failure, scope, [record, operation]);
            }
            Ext.callback(config.callback, scope, [record, operation]);*/
        };


        proxy.read(operation, callback, this);
    }
});

Model:

Ext.define('Intelliplan.Data.System.Session.Query.SessionConfiguration', {
    extend: 'Intelliplan.Base.Data.Query',
    config: {
    idProperty: 'id',
    proxy: Ext.create('Intelliplan.Base.Proxy.Standard', {
        url: Intelliplan.Api.BaseUrl + '/System/Session/GetSessionConfiguration'
    }),
    fields: [
        {
            name: 'userId'
        },
        {
            name: 'languageCode'
        },
        {
            name: 'formats'
        },
        {
            name: 'calendar'
        },
        {
            name: 'phrases'
        },
        {
            name: 'firstName'
        },
        {
            name: 'surName'
        },
        {
            name: 'fullName'
        },
        {
            name: 'userCompanyNo'
        },
        {
            name: 'userCompanyName'
        },
        {
            name: 'features'
        }
    ]
    }
});

So basically my question is: Is this a bug or am I doing something wrong?

What does Model equate to?

[jakobgrannas]

I'm not at work at the moment, so I can't check for sure, but it's an object (I think it's a model) containing (from what I can remember):

data (contains all the fields defined in the model. Field properties are all empty, as they should be)
node (same, I think)
id: null (not 100% sure about this one)
raw: don't remember
...Some other stuff I can't remember

I realize that this might not be very helpful, so I'll get back to you when I know for sure what Model contains.

Try changing this to:

Ext.define('Intelliplan.Base.Data.Query', {
    extend: 'Ext.data.Model',
    execute: function(params, successHandler, scope) {


        var config = {
            action: 'read',
            params: params,
            model: this.self
        };


        var operation = Ext.create('Ext.data.Operation', config)
        ...

        var config = {
            action: 'read',
            params: params,
            model: this.self
        };


        var operation = Ext.create('Ext.data.Operation', config)

EDIT: It worked! Thanks a lot! Would you mind explaining why it worked?
