嗨 StackOverflow 用户！

我有一些 json 数据，应该将其加载到具有三个关联的模型中。其中两个是好的，但第三个是行不通的。

这是来自服务器的 json 回复：http: //pastebin.com/geL16BvL

主要型号：

Ext.define('Invoice', {
extend: 'Ext.data.Model',
fields: [
    {name: 'id', type: 'int'},
    {name: 'invoice_id', type: 'string'},
    {name: 'invoice_date', type: 'date', dateFormat: 'time'},
    {name: 'invoice_due_date', type: 'date', dateFormat: 'time'},
    {name: 'invoice_year_index', type: 'int'},
    {name: 'invoice_total', type: 'number'},
    {name: 'invoice_vat', type: 'number'},
    {name: 'invoice_delivery', type: 'number'},
    {name: 'invoice_total_cost', type: 'number'},
    {name: 'invoice_payment_method', type: 'string'},
    {name: 'invoice_status', type: 'string'},
    {name: 'invoice_discount', type: 'number'},
    {name: 'invoice_discount_type', type: 'string'},
    {name: 'invoice_fixed_charges', type: 'number'},
    {name: 'invoice_currency_code', type: 'string'},
    {name: 'invoice_currency_symbol', type: 'string'},
    {name: 'localization_data_source', type: 'string', mapping: 'data_source.data_source_name'}
],
associations: [
    {model: 'Contractor', name: 'contractor', type: 'hasOne'},
    {model: 'SalesRepresentative', name: 'salesRepresentative', type: 'hasOne', associationKey: 'salesRepresentative'},
    {model: 'InvoiceItem', name: 'invoiceItems', type: 'hasMany'}
]

});

两个工作：

Ext.define('InvoiceItem', {
extend: 'Ext.data.Model',
belongsTo: 'Invoice',
fields: [
    {name: 'id', type: 'int'},
    {name: 'invoice_id', type: 'string'},
    {name: 'item_variation_id', type: 'string'},
    {name: 'item_quantity', type: 'number'},
    {name: 'item_name', type: 'string'},
    {name: 'item_price', type: 'number'},
    {name: 'item_value', type: 'number'},
    {name: 'item_position_vat', type: 'number'},
    {name: 'item_vat', type: 'number'},
    {name: 'item_tax', type: 'number'},
    {name: 'item_category_name', type: 'string'},
    {name: 'item_discount', type: 'number'},
    {name: 'item_price_before_discount', type: 'number'}
]

});

Ext.define('Contractor', {
    extend: 'Ext.data.Model',
    fields: [
        {name: 'id', type: 'int'},
        {name: 'contractor_id', type: 'string'},
        {name: 'contractor_email', type: 'string'},
        {name: 'contractor_status', type: 'string'},
        {name: 'contractor_registered', type: 'date', dateFormat: 'time'},
        {name: 'contractor_name', type: 'string'},
        {name: 'contractor_company', type: 'string'},
        {name: 'contractor_company_vat_no', type: 'string'},
        {name: 'contractor_phone', type: 'string'},
        {name: 'contractor_address', type: 'string'},
        {name: 'contractor_city', type: 'string'},
        {name: 'contractor_postcode', type: 'string'},
        {name: 'contractor_country', type: 'string'}
    ]
});

第三个 - 销售代表：

Ext.define('SalesRepresentative', {
extend: 'Ext.data.Model',
belongsTo: 'Invoice',
fields: [
    {name: 'id', type: 'int'},
    {name: 'representative_id', type: 'string'},
    {name: 'representative_name', type: 'string'},
    {name: 'representative_email', type: 'string'}
]

});

当我使用 InvoiceDetails 访问 Contractor 或 store 时，一切都很好。但是，当我尝试通过以下方式访问 SalesRepresentative 时：

Ext.getStore('invoicesStore').getAt(0).getSalesRepresentative()

我收到“TypeError: url is return url + (url.indexOf('?') === -1 ? '?' : '&') + string;”

我很确定关系有问题，但我找不到让它工作的方法。

您的商店可能使用 AJAX 代理（或任何其他从Ext.data.proxy.Server派生的代理）并尝试通过服务器请求加载销售代表记录，但无法在模型上找到 URL。

尝试添加

proxy: {
    type: 'memory'
}

到你的模型。
