Question

我有一个1：n的关系：

class Parent {  
  protected $title = '';  

 /**  
  * @var \TYPO3\CMS\Extbase\Persistence\ObjectStorage<\...\Child>  
  * @lazy  
  */
 protected $allChildren = NULL;

public function addChild(\...\Child $child) {
    $this->allChildren->attach($child);
}

}  
class Child {  
  /**
    * reference to the parent object
    * @var Parent
    */
    protected $parent = NULL;  

    public function getParent() {
      if ($this->parent instanceof \TYPO3\CMS\Extbase\Persistence\LazyLoadingProxy) {
        $this->parent->_loadRealInstance();
      }
      return $this->parent;
    }
}

通常，当从数据库中读取子对象时（例如，通过findByUid），它们已经引用了父对象。

但是如果我创建一个新的子对象并立即保留它 - 从数据库和父引用中获取uid - 不是。
这是上面描述的父类中的函数：

public function appendNewChild() {
        $objectManager = \TYPO3\CMS\Core\Utility\GeneralUtility::makeInstance('TYPO3\\CMS\\Extbase\\Object\\ObjectManager');
        $child = $objectManager->get(\...\Child::class);
        $this->addChild($child);
        $objectManager->get(\...\ParentRepository::class)->update($this);
        $objectManager->get(\...\PersistenceManager::class)->persistAll();
        //at this point is child's 'uid' property updated. 'parent' - is not.

        return $child;
    }

我也试过

$child = $objectManager->get(\...\ChildRepository::class)->findByUid($child->getUid());

调用persistAll()后

- 没有效果。看起来这个对象是由ExtBase缓冲的，而不是再次读取。

修改

这是儿童模特：

<?php

    /**

    protected $ready = FALSE;

    /**

    protected $tstamp = 0;

    /**

注意TCA表配置。这应该工作。
