Symfony 教条主义者不为自己的实体工作

我有

客户

，

产品

，

预算

和

预算项目

实体<代码>预算与@ORM\manytone与

客户

相关，与@ORM\OneToMany与

预算项

相关<代码>预算项与

产品

和

预算

关联为@ORM\manytone

在

BudgetItem

中，有一种方法可用于计算先前选择的

产品的总价格，然后将其保存到
预算项目
表中。更新项目时，将执行代码并再次成功地将其保存到数据库中。方法如下：

public function calculateTotalPrice()
{
    return $this->getProduct()->getPrice() * $this->getMeters();
}

/**
 * @ORM\PrePersist
 */
public function onPreEvents()
{
    $this->setPrice($this->calculateTotalPrice());
}

现在，我有了
预算
：

/**
 * @return \DateTime
 */
public function generateNextPaymentDate()
{
    if ($this->getStartsAt() !== null) {
        $date = new \DateTime($this->getStartsAt()->format('Y-m-d'));
        return $date->add(new \DateInterval('P' . $this->getCheckFor() . 'D'));
    }
}

/**
 * @return decimal
 */
public function calculateTotalBudgetPrice()
{
    $totalBudgetPrice = 0;

    foreach ($this->getItems() as $item) {
        $totalBudgetPrice += $item->getPrice();
    }

    return $totalBudgetPrice;
}

/**
 * @return decimal
 */
public function calculateInstallmentRatePrice()
{
    return $this->calculateTotalBudgetPrice() / $this->getInstallmentRate();
}

/**
 * @ORM\PrePersist
 */
public function onPreEvents()
{
    $this->setNextPaymentDate($this->generateNextPaymentDate());
    $this->setInstallmentRatePrice($this->calculateInstallmentRatePrice());
    $this->setTotalBudgetPrice($this->calculateTotalBudgetPrice());
}

在编辑
预算
后，所有这些方法的结果都不会保留到数据库中。如果我理解得很好，Doctrine2似乎不会更新其他相关实体，但这些字段属于该实体。我还需要做什么

编辑

BudgetController
，我在其中持久化并刷新

EDIT2

我刚刚意识到@ORM\PreUpdate正在运行，但仅适用于我的

请参见，特别是预科生

应注意，此事件仅在初始启动时触发
实体的持久化（即，它不会在将来的更新中触发）

因此，您还需要添加一个预更新侦听器。

我刚刚看到了它。更新后执行
calculateTotalPrice
方法，因为它实际上是一个设置总值的JavaScript函数。这种方法实际上是无用的。但是，添加预更新仍然不起作用。我在PrePersist下面添加了注释，或者我需要创建另一个方法？您的实体上是否设置了@ORM\HasLifecycleCallbacks？您可以在单个方法上同时设置更新/持久化，这样就不会有问题了。是的，我会这样做，因为我创建了它。我看不出您所做的有任何错误。我甚至在本地测试了一个类似的类型方法，它可以在实体的创建和更新上工作。请你看看我在Github中的项目，看看我是否做错了什么？我刚看到。更新后执行
