我有以下模型并存储在我的应用中。
我的问题是,当我尝试将记录加载到第二个存储中时,它不起作用。我尝试了不同的存储方法,但一无所获(Store Manual)。
在我的应用程序中,第一个商店记录被加载到控制器中,在该控制器中,Ajax调用接收到data.products
变量。
有什么想法我做错了吗?
PS:我正在使用ExtJs 4.1

最佳答案
显然,这两个设置是:
autoLoad: true,
autoSync: true
破坏整个存储,并用空记录(由
load
,loadRawData
,loadRecords
,clearFilter
触发)调用filter
。将这两个设置为
false
后,加载仅在显式调用load方法时发生。Ext.define('App.model.Product', {
extend: 'Ext.data.Model',
alias: 'model-product',
idgen: 'sequential',
fields: [
{ name: 'available', type: 'boolean', useNull: false, defaultValue: true },
{ name: 'country', type: 'int', useNull: false },
{ name: 'key', type: 'string', useNull: false },
{ name: 'name', type: 'string', useNull: false }
],
proxy: {
type: 'memory',
reader: {
type: 'json',
root: 'products'
}
}
});
Ext.define('App.store.Product', {

autoLoad: false,
autoSync: false,

this.filter('country', countryId);
return this;
},
getRecordsForCountry: function (countryId) {
var records = [];
this.findBy(function (record) {
if (record.get('country') === countryId) {
records.push(record.copy());
