Using Ext JS 4.1....

I have a grid that displays a bunch of Model instances, although only some of the fields are displayed. I then have a double-click listener where I would like to load the entire record into a form for editing. In the double-click listener I do not see the data in my hasMany association although the json data is being returned according to Firebug's Net display where I see the response from the server call. Is there something wrong with my model or am I going about this wrong?

Request.js

Ext.define('Request', {
extend: 'Ext.data.Model',
requires: ['PointOfContact'],
fields: [
{name: 'id', type: 'int'},
{name: 'project', type: 'string'},
{name: 'purpose', type: 'string'},
{name: 'status'},
{name: 'additionalInfo', type: 'string'}
],
hasMany: [{
model: 'PointOfContact',
name: 'pointOfContacts',
foreignKey: 'id',
associationKey: 'pointOfContacts'
}],
proxy: {
type: 'rest',
url: '/web/project/rest/request/',
reader: { type: 'json' },
writer: { type: 'json' }
}
});

PointOfContact.js

Ext.define('PointOfContact', {
extend: 'Ext.data.Model',
fields: [
{name: 'id', type: 'int'},
{name: 'fullName', type: 'string'},
{name: 'email', type: 'string'},
{name: 'phone', type: 'string'}
]
});

Requests.js

Ext.define('Requests', {
extend: 'Ext.data.Store',
model: 'Request',
autoLoad: true
});

RequestsView.js

Ext.define('RequestsView', {
extend: 'Ext.grid.Panel',
title: 'All Requests',
store: 'Requests',
viewConfig: {
singleSelect: 'true',
listeners: {
itemdblclick: function(dataview, record, item, index, e) {
console.log(record.get('project'));
console.log(record.get('purpose'));
console.log(record.get('status'));
console.log(record.get('additionalInfo'));
console.log(record.get('pointOfContacts'));
var comp = Ext.ComponentQuery.query('requestForm');
comp[0].getForm().loadRecord(record);
var mainPanel = Ext.ComponentQuery.query('mainpanel');
mainPanel[0].getLayout().setActiveItem('requestForm');
}
}
},
columns: [
{header: 'Project', dataIndex: 'project', flex: 1},
{header: 'Purpose', dataIndex: 'purpose', flex: 1},
{header: 'Status', dataIndex: 'status', flex: 1}
]
});

So in the console I see the values for project, purpose, status and additionalInfo but I get "undefined" for pointOfContacts.

Any suggestions?

console.log(record.get('pointOfContacts'));

The get method is for accessing fields but you haven't defined a field called pointOfContacts.

A hasmany association will create an accessor for the associated data store. You'd do something like this:


console.log(record.pointOfContacts());
