Question

我正在尝试在集会中创建自定义html应用。在将添加该应用程序的页面中，我有一个发布过滤器。我想为用户选择的发行版创建功能列表。通过在存储中为功能部件定义过滤器，看起来我应该能够将用户选择的版本的_ref字段与功能部件的Release._ref匹配。我认为它不起作用，因为某些功能未定义发布，因此当过滤器尝试检查Release._ref时，Release为null，因此引发null引用错误。这似乎是一件非常基本的事情。正确的方法是什么？

我认为很重要的

snipit代码：

console.log('_loadData');
    var timeBoxScope = this.getContext().getTimeboxScope().record.data._ref; // only works in Rally for custom page with Release filter
    console.log('timebox', timeBoxScope);

    var myStore = Ext.create('Rally.data.wsapi.Store', {
    model: 'PortfolioItem/Feature',
    pageSize: 10,
    autoLoad: true,
    fetch: ['FormattedID', 'Name', 'Owner', 'Release', 'UserStories'],
    filters: [
    {
        property: 'Release._ref',
        operator: '=',
        value: timeBoxScope
         }],
    listeners: {

我正在研究的全部内容：

Ext.define('CustomApp', {
extend: 'Rally.app.App',
componentCls: 'app',
launch: function () {
    console.log('launch');
    this._loadData();
},
// load rally data
_loadData: function () {
    console.log('_loadData');
    var timeBoxScope = this.getContext().getTimeboxScope().record.data._ref; // only works in Rally for custom page with Release filter
    console.log('timebox', timeBoxScope);

    var myStore = Ext.create('Rally.data.wsapi.Store', {
    model: 'PortfolioItem/Feature',
    pageSize: 10,
    autoLoad: true,
    fetch: ['FormattedID', 'Name', 'Owner', 'Release', 'UserStories'],
    filters: [
    {
        property: 'Release._ref',
        operator: '=',
        value: timeBoxScope
         }],
    listeners: {
        load: function(store, data){
            var features = [];
            var pendingstories = data.length;
            //debugger;
            Ext.Array.each(data, function(feature) {
                        var f  = {
                            FormattedID: feature.get('FormattedID'),
                            Name: feature.get('Name'),
                            _ref: feature.get("_ref"),
                            Owner: feature.get("Owner")._refObjectName,
                            StoryCount: feature.get('UserStories').Count,
                            UserStories: []
                        };
console.log('feature', feature);
console.log('feature release', feature.data.Release._ref);
                        var stories = feature.getCollection('UserStories');
                       stories.load({
                            fetch: ['FormattedID'],
                            callback: function(records, operation, success){
                                Ext.Array.each(records, function(story){
                                    var number = story.get('DirectChildrenCount');  
                                    if (number == 0) {
                                        f.UserStories.push({_ref: story.get('_ref'),
                                                    FormattedID: story.get('FormattedID')

                                }, this);

                                --pendingstories;
                                if (pendingstories === 0) {

                                }
                            },

                }
            }
        ]

    });
}

} ）;

我自己找到了答案。正如我所怀疑的那样，我做错了。这是设置过滤器的方法。请参见下面的“过滤器”定义：

var timeBoxScope = this.getContext().getTimeboxScope();//.record.data._ref; // only works in Rally for custom page with Release filter
    console.log('timebox', timeBoxScope);
var myStore = Ext.create('Rally.data.wsapi.Store', {
    model: 'PortfolioItem/Feature',
    pageSize: 10,
    autoLoad: true,
    fetch: ['FormattedID', 'Name', 'Owner', 'Release', 'UserStories'],
    filters: timeBoxScope.getQueryFilter(),
    listeners: {
