Sylius - 如何添加自定义促销操作？

时间：2017-04-20 10:10:44

标签： sylius

我已按照列出的教程[输入链接说明here。

但是，当我尝试使用此操作添加促销时，我收到此错误：

Could not load type "AppBundle\Promotion\Action\CheapestProductDiscountPromotionActionCommand"

经过进一步调查，CheapestProductDiscountPromotionActionCommand.php会浏览FormRegistry.php中的以下代码块：

if (class_exists($name) && in_array('Symfony\Component\Form\FormTypeInterface', class_implements($name))) {
    $type = new $name();
} else {
    throw new InvalidArgumentException(sprintf('Could not load type "%s"', $name));
}

从我可以收集的信息来看，它正在检查CheapestProductDiscountPromotionActionCommand.php是否实现FormTypeInterface，但我不完全确定原因？我认为CheapestProductDiscountConfigurationType扩展AbstractType实现了FormTypeInterface？也许我错了，但我认为CheapestProductDiscountPromotionActionCommand.php不应该通过上面的代码块？

我的堆栈跟踪如下：

答案 0 :(得分：0)

我在CheapestProductDiscountPromotionActionCommand中找到了这个问题。

在列出的{somius文档here：

中 
/**
    * {@inheritdoc}
*/
public function getConfigurationFormType()
{
    return CheapestProductDiscountPromotionActionCommand::class;
}

然而，这应该是：

/**
    * {@inheritdoc}
*/
public function getConfigurationFormType()
{
    return CheapestProductDiscountConfigurationType::class;
}

这就是代码检查CheapestProductDiscountPromotionActionCommand.php实现FormTypeInterface的原因。

我设法添加了我的自定义操作并且它的工作完美。 sylius文档存在一些问题，但实现有效：）。
