Sylius - 如何添加自定義促銷操作？

我按照列出的教程[輸入鏈接說明here。Sylius - 如何添加自定義促銷操作？

然而，當我嘗試添加促進與這個動作，我得到這個錯誤：

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

經進一步調查，CheapestProductDiscountPromotionActionCommand.php經過下面的代碼塊FormRegistry.php：

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)); 
}

從我可以收集，它是檢查是否CheapestProductDiscountPromotionActionCommand.php實施FormTypeInterface但我不完全確定爲什麼？我以爲CheapestProductDiscountConfigurationType延伸AbstractType其實施FormTypeInterface？也許我錯了，但我會認爲CheapestProductDiscountPromotionActionCommand.php不應該通過上述代碼塊？

我的堆棧跟蹤如下：

我發現問題CheapestProductDiscountPromotionActionCommand。

在sylius文檔中列出here：

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

但是這應該是：

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

這就是爲什麼代碼檢查發現CheapestProductDiscountPromotionActionCommand.php實現FormTypeInterface。

我成功地添加了我的自定義動作及其工作。 sylius文檔有幾個問題，但實現工作:)。
