Sylius - カスタムプロモーションアクションを追加するにはどうすればよいですか？

Question

私はチュートリアル[リンクの説明を入力してくださいhereに従ってください。

私はこのアクションでプロモーションを追加しようとすると、しかし、私はこのエラーを取得：さらに調査時

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

、CheapestProductDiscountPromotionActionCommand.phpはFormRegistry.php次のコードブロックを通過：

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)); 
} 

私が集めることのできるところから、CheapestProductDiscountPromotionActionCommand.phpがFormTypeInterfaceを実装しているかどうかを確認していますが、なぜ完全にわからないのですか？私はCheapestProductDiscountConfigurationTypeをAbstractTypeに拡張し、FormTypeInterfaceを実装すると考えましたか？たぶん私は間違っているが、私は上記のコードブロックを通過するべきではないと考えているだろうCheapestProductDiscountPromotionActionCommand.php？

次のように私のスタックトレースは次のとおりです。

Answer 1

私はCheapestProductDiscountPromotionActionCommandで問題を発見しました。 syliusのドキュメントで

がhere上場：

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

しかし、これは次のようになります。コードはCheapestProductDiscountPromotionActionCommand.phpがFormTypeInterfaceを実装していることを確認し、なぜ

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

です。

Iveは自分のカスタムアクションとその動作を完全に追加することができました。 syliusのドキュメントにはいくつかの問題がありますが、実装はうまくいきます:)
