如何在 magento 2.3 中以默认顺序 Api 响应获取自定义订单属性

How to get the custom order attributes in default order Api response in magento 2.3

我创建了一个名为 delivery_date 的新自定义订单属性,并在销售订单网格中显示了相同的属性,但我没有在我的订单 Api 响应中获得自定义属性。

我收到的错误是致命错误:未捕获错误:调用未定义的方法 Magento\Sales\Api\Data\OrderExtension::setTipAndTrickAttribute()

请帮忙

为了回答您有关错误的问题,您使用了错误的魔法函数。该属性的魔法函数是 setDeliveryDate().

您还需要确保您的 events.xml 有合适的 class 观察者。

<observer name="sales_order_load_delivery_date" instance="Magestore\TipAndTrick\Observer\Sales\OrderLoadAfter" />

而您的观察者 class 是:Amos\CustomOrder\Observer\Sales\OrderLoadAfter

当您使用示例 material 时,尽量不要忘记在需要时更改 class、命名空间和函数名称等。您可能还需要一个订单存储库插件才能真正将其放入 API 响应中。

<type name="Magento\Sales\Api\OrderRepositoryInterface">
    <plugin name="your_name_here_extension_attribute"
                type="<Vendor>\<Module>\Plugin\OrderRepositoryPlugin" />
</type>
