Question

我无法让它正常工作。它将插入两次条目，并且永远不会在project_data表中设置project_id，它始终为0。我试过插入多种方式..

喜欢这样

//... do some work
$project = new PSD_Model_Entity_Project();
$project->setStatusId($this->_em->find("PSD_Model_Entity_Status", '3'));
$project->addData('hello', $data->data->hello);

$this->_em->persist($project);
$this->_em->flush();

就像这样

$project = new PSD_Model_Entity_Project();
$project->setStatusId($this->_em->find("PSD_Model_Entity_Status", '3'));

$project_data = new PSD_Model_Entity_Project_Data('hello', $data->data->hello,$project);

$this->_em->persist($project);
$this->_em->persist($project_data);
$this->_em->flush();

Answer 1

根据文档，我认为您的数据模型属性应标记为protected，而不是private。

$project_id中对PSD_Model_Entity_Project_Data的引用目前有：

/**
 * @Column(type="integer")
 * @ManyToOne(targetEntity="PSD_Model_Entity_Project", inversedBy="data")
 */

您可以尝试将Column更改为JoinColumn：

/**
 * @JoinColumn()
 * @ManyToOne(targetEntity="PSD_Model_Entity_Project", inversedBy="data")
 */

是的，我有一个类似的模型，不需要inversedBy;但是自从我触及Doctrine以来已经有一段时间了，所以这可能没有任何区别:)）

Answer 2

试试这个。尝试通过集合设置属性，而不是使用构造函数设置属性，并查看是否消除了重复的行。
