复制extbase存储库对象 [英] Duplicating extbase repository object

问题描述

在我的extbase/fluid项目中，除了创建，删除，列表等标准动作外，我还想创建模型类对象的副本，并将其存储在存储库中.使用findall()，所有对象都显示在一个列表中，并且相应的操作(如delete，edit)显示在每个对象的旁边.为了复制对象，我在相应的控制器中创建了一个复制动作，下面是代码:

In my extbase/fluid project,in addition to standard actions such as create,delete,list etc, I want to create a duplicate of a model class object which are stored in a repository. Using findall(), all objects are displayed in a list and corresponding actions such as delete,edit are displayed next to each. For duplicating an object, I have created a duplicate action in the corresponding controller and here is the code:

public function dupcliateAction(Tx_CcCompanylogin_Domain_Model_MyObject $testObject)
{
 $this->myObjectRepository->add($testObject);
 $this->redirect('list');//Lists the objects again from the repository
}

似乎已经足够僵硬，但是没有向存储库添加任何新对象，并且没有收到错误.我已经检查了文档，也没有显式的复制方法.

Seems straitforward enough but no new object is added to the repository and I am not getting an error.I have checked the documentation and there is no explicit method available for duplicating.

推荐答案

注意:克隆对象时，PHP 5将执行该对象所有属性的浅表副本.引用其他变量的任何属性都将保留为引用.

Note : When an object is cloned, PHP 5 will perform a shallow copy of all of the object's properties. Any properties that are references to other variables, will remain references.

或者，您可以使用反射来创建对象的(深层)副本.

Alternative you can use reflection to create a (deep) copy of your object.

    $productClone = $this->objectManager->create('Tx_Theext_Domain_Model_Product');

// $product = source object
    $productProperties = Tx_Extbase_Reflection_ObjectAccess::getAccessibleProperties($product);
    foreach ($productProperties as $propertyName => $propertyValue) {
        Tx_Extbase_Reflection_ObjectAccess::setProperty($productClone, $propertyName, $propertyValue);
    }

// $productAdditions = ObjectStorage property
    $productAdditions = $product->getProductAddition();
    $newStorage = $this->objectManager->get('Tx_Extbase_Persistence_ObjectStorage');
    foreach ($productAdditions as $productAddition) {
        $productAdditionClone = $this->objectManager->create('Tx_Theext_Domain_Model_ProductAddition');
        $productAdditionProperties = Tx_Extbase_Reflection_ObjectAccess::getAccessibleProperties($productAddition);
        foreach ($productAdditionProperties as $propertyName => $propertyValue) {
            Tx_Extbase_Reflection_ObjectAccess::setProperty($productAdditionClone, $propertyName, $propertyValue);
        }
        $newStorage->attach($productAdditionClone);
    }
    $productClone->setProductAddition($newStorage);
// This have to be repeat for every ObjectStorage property, or write a service.
