细节
我有一个用于显示发票信息的网格。使用 Invoice 存储填充网格，Invoice 存储使用 Invoice 模型，Invoice 模型与 InvoiceStatus 模型具有“具有一个”关联，主键为“id”，前键为“invoice_status_id”。
问题
我不确定如何使 Invoice Grid 的“Status”列的显示值使用插入 invoice_status_id 的关联模型“name”。我知道我需要创建一个渲染器来执行此操作，但是我仍然得到一个空值。Invoice 和 InvoiceStatus 存储都填充了正确的值。
状态列渲染
renderer: function(value, metaData, record, rowIndex, colIndex, store, view) {
return record.getStatus().get('name');
},
