当我创建 WsapiDataStore 时，store.data.items 和 store.data.keys 返回空数组，尽管我在执行 console.log(store.data) 时能够看到键和项目
store = Ext.create('Rally.data.WsapiDataStore', {
model: 'Defect',
context: {
project: '/project/xxxxxx'
},
autoLoad: true,
fetch: ['Rank', 'FormattedID', 'Name']
});
console.log(store.data)的输出:
constructor {items: Array[0], map: Object, keys: Array[0], length: 0, allowFunctions: false…}
allowFunctions: false
events: Object
generation: 8
getKey: function (record) {
hasListeners: HasListeners
items: Array[7]
keys: Array[7]
length: 7
map: Object
sorters: constructor
__proto__: TemplateClass
请注意第一行如何显示“items: Array[0]”和“keys: Array[0]”，但展开时它显示“items: Array[7]”和“keys: Array[7]”。当我进一步展开时，我还可以看到 7 条记录。
当我添加加载监听器并从监听器函数访问数据时，一切都会按预期工作(但我不想这样做)
最佳答案
我认为最好的方法是通过两个 Rally.data.WsapiDataStore 处理数据。您需要将两个存储的监听器链接在一起，以便正确处理异步加载。下面是一个说明该过程的示例:
<!DOCTYPE html>
<html>
<head>
<title>MultipleModelExample</title>
<script type="text/javascript" src="https://rally1.rallydev.com/apps/2.0p5/sdk.js"></script>
<script type="text/javascript">
Rally.onReady(function() {
Ext.define('CustomApp', {
extend: 'Rally.app.App',
componentCls: 'app',
// Combined Story/Defect Records
dataRecords: null,
launch: function() {
//Write app code here
this.dataRecords = [];
Rally.data.ModelFactory.getModels({
types: ['HierarchicalRequirement','Defect'],
scope: this,
success: function(models) {
this.myModels = models;
this.storyStore = Ext.create('Rally.data.WsapiDataStore', {
model: models.HierarchicalRequirement,
fetch: true,
autoLoad: true,
remoteSort: true,
sorters: [
{ property: 'FormattedID', direction: 'Asc' }
],
listeners: {
load: this._processStories,
scope: this
}
});
}
});
},
_processStories: function(store, records, successful, opts) {
var storyRecords = [];
Ext.Array.each(records, function(record) {
//Perform custom actions with the data here
//Calculations, etc.
storyRecords.push({
FormattedID: record.get('FormattedID'),
Name: record.get('Name'),
Description: record.get('Description')
});
});
this.dataRecords = storyRecords;
this.defectStore = Ext.create('Rally.data.WsapiDataStore', {
model: this.myModels.Defect,
fetch: true,
autoLoad: true,
remoteSort: true,
sorters: [
{ property: 'FormattedID', direction: 'Asc' }
],
listeners: {
load: this._processDefects,
scope: this
}
});
},
_processDefects: function(store, records, successful, opts) {
var defectRecords = [];
Ext.Array.each(records, function(record) {
//Perform custom actions with the data here
//Calculations, etc.
defectRecords.push({
FormattedID: record.get('FormattedID'),
Name: record.get('Name'),
Description: record.get('Description')
});
});
var combinedRecords = defectRecords.concat(this.dataRecords);
this.add({
xtype: 'rallygrid',
store: Ext.create('Rally.data.custom.Store', {
data: combinedRecords,
pageSize: 25
}),
columnCfgs: [
{
text: 'FormattedID', dataIndex: 'FormattedID'
},
{
text: 'Name', dataIndex: 'Name', flex: 1
},
{
text: 'Description', dataIndex: 'Description', flex: 1
}
]
});
}
});
Rally.launchApp('CustomApp', {
name: 'MultipleModelExample'
});
});
</script>
<style type="text/css">
.app {
/* Add app styles here */
}
</style>
</head>
<body></body>
