create/update user story using rally app sdk - extjs

Question

Until now, I have been querying the data stores using Rally App SDK, however, this time I have to update a story using the js sdk. I tried looking up for examples for some sample code that demonstrates how the App SDK can be used to update/add values in Rally. I have been doing CRUD operations using Ruby Rally API but never really did it with the app sdk.
Can anyone provide some sample code or any link to where I could check it out?
Thanks

See this help document on updating and creating reocrds. Below are examples - one updates a story, the other creates a story. There is not much going on in terms of UI: please enable DevTools console to see console.log output.
Here is an example of updating a Defect Collection on a User Story:
Ext.define('CustomApp', {
extend: 'Rally.app.App',
componentCls: 'app',
launch: function() {
console.log("launch");
Rally.data.ModelFactory.getModel({
type: 'User Story',
success: this._onModelRetrieved,
scope: this
});
},
_onModelRetrieved: function(model) {
console.log("_onModelRetrieved");
this.model = model;
this._readRecord(model);
},
_readRecord: function(model) {
var id = 13888228557;
console.log("_readRecord");
this.model.load(id, {
fetch: ['Name', 'Defects'],
callback: this._onRecordRead,
scope: this
});
},
_onRecordRead: function(record, operation) {
console.log('name...', record.get('Name'));
console.log('defects...', record.get('Defects'));
if(operation.wasSuccessful()) {
//load store first by passing additional config to getCollection method
var defectStore = record.getCollection('Defects', {
autoLoad: true,
listeners: { load: function() {
//once loaded now do the add and sync
defectStore.add({'_ref':'/defect/13303315495'});
defectStore.sync({
callback: function() {
console.log('success');
}
});
}}
});
}
},
});
Here is an example of creating a user story, setting a project and scheduling for an iteration:
Ext.define('CustomApp', {
extend: 'Rally.app.TimeboxScopedApp',
componentCls: 'app',
scopeType: 'iteration',
comboboxConfig: {
fieldLabel: 'Select an Iteration:',
labelWidth: 100,
width: 300
},
addContent: function() {
this._getIteration();
},
onScopeChange: function() {
this._getIteration();
},
_getIteration: function() {
var iteration = this.getContext().getTimeboxScope().record.get('_ref');
console.log('iteration',iteration);
if (!this.down('#b2')) {
var that = this;
var cb = Ext.create('Ext.Container', {
items: [
{
xtype : 'rallybutton',
text : 'create',
id: 'b2',
handler: function() {
that._getModel(iteration);
}
}
]
});
this.add(cb);
}
},
_getModel: function(iteration){
var that = this;
Rally.data.ModelFactory.getModel({
type: 'UserStory',
context: {
workspace: '/workspace/12352608129'
},
success: function(model) { //success on model retrieved
that._model = model;
var story = Ext.create(model, {
Name: 'story 777',
Description: 'created via appsdk2'
});
story.save({
callback: function(result, operation) {
if(operation.wasSuccessful()) {
console.log("_ref",result.get('_ref'), ' ', result.get('Name'));
that._record = result;
that._readAndUpdate(iteration);
}
else{
console.log("?");
}
}
});
}
});
},
_readAndUpdate:function(iteration){
var id = this._record.get('ObjectID');
console.log('OID', id);
this._model.load(id,{
fetch: ['Name', 'FormattedID', 'ScheduleState', 'Iteration'],
callback: function(record, operation){
console.log('ScheduleState prior to update:', record.get('ScheduleState'));
console.log('Iteration prior to update:', record.get('Iteration'));
record.set('ScheduleState','In-Progress');
record.set('Iteration', iteration);
record.set('Project', '/project/12352608219')
record.save({
callback: function(record, operation) {
if(operation.wasSuccessful()) {
console.log('ScheduleState after update..', record.get('ScheduleState'));
console.log('Iteration after update..', record.get('Iteration'));
}
else{
console.log("?");
}
}
});
}
})
}
});
