编辑表单中的 Laravel Orchid 数据绑定

Question

我在 Laravel orchid 平台中有以下代码，我正在尝试更新一个字段以及可以选择多个的关系字段。在添加新表单上，我添加了这些属性，并且它们已被插入到表格中，但它们并未在编辑表单中显示为选中状态。有人可以帮忙吗？

//EditPackageScreen.php

在包编辑页面上，选定的测试不显示

Answer 1

没关系，问题出在包本身。我已经和作者谈过了，他已经发布了一个新版本来解决这个问题。

你忘记了 $target 从数据库中获取数据.. 将此添加到您的 PackageEditLayout

/**
    * Data source.
    *
    * @var string
    */
   public $target = 'package';
