Question

目前，我正在为我的客户开发自定义忠诚度计划。我将在单独的标签中显示这些点。 忠诚度计划＆gt; （顾客名单）＆gt; （查看他们的观点）＆gt; （编辑点）

当我点击一个客户时，它将呈现客户点的列表，但是渲染没有问题，但它显示以下错误。

无法加载（或找到）对象

请帮助我克服这个错误。

Answer 1

renderView（）
不需要以下代码
$ this-＆gt; table =＆＃39; loyaltyprogram＆＃39 ;; $ this-＆gt; className =＆＃39; LoyaltyClass＆＃39 ;; $ this-＆gt; module =＆＃39; loyaltyprogram＆＃39;;
您需要包含类文件：

require_once（目录名（文件）＆＃39; /../../类/ LoyaltyClass.php＆＃39）;

您不需要创建LoyaltyClas的新实例，而是需要调用loadObject（）方法，因为它设置了$ this-＆gt;对象，如：

if（！（$ obj = $ this-＆gt; loadObject（true）））返回;

如果你不在renderList（）中使用$ obj，你就不必加载它。
