条令2@版本没有；不起作用

我尝试使用Doctrine2实现一个可版本控制的ORM。

一切都很好。更新现有条目时，旧条目将插入到*_version表中。

但是，当我更新另一个请求中的条目（并因此更新EntityManager的新实例）时，旧条目将不再写入*_version表，尽管基本表中的条目得到了更新而没有任何问题（甚至版本号增加了1）。

我想向你展示我的非常简单的可版本ORM:

更新：下面的示例代码现在可以工作了

同时使用logEntityVersion辅助方法检查我的Gist。

ProductBase.php

trait ProductBase
{
    /** 
     * @ORM'Id 
     * @ORM'Column(type="integer")
     * @ORM'GeneratedValue(strategy="IDENTITY")
     */
    protected $id;
    /** 
     * @ORM'Column(type="string") 
     */
    protected $name;
    // getters and setters here
}

Product.php

use Doctrine'Common'Collections'ArrayCollection;
use Doctrine'ORM'Mapping as ORM;
/**
 * Product
 *
 * @ORM'Entity
 * @ORM'Table(name="product")
 * @ORM'HasLifeCycleCallbacks
 */
class Product
{
    use ProductBase;
    /**
     * @ORM'OneToMany(targetEntity="ProductVersion", mappedBy="product", cascade={"persist"})
     */
    private $auditLog;
    /**
     * @ORM'Column(type="integer")
     * @ORM'Version
     */
    private $version = 1;
    public function __construct()
    {
        $this->auditLog = new ArrayCollection();
    }
    public function logVersion()
    {
        echo sprintf("Creating a new version for ID %s, version %s'n", $this->getId(), $this->getVersion());
        $this->auditLog[] = new ProductVersion($this);
    }
    // Version getter and setter
}

ProductVersion.php

use Doctrine'ORM'Mapping as ORM;
/**
 * ProductVersion
 *
 * @ORM'Entity
 * @ORM'Table(name="product_version")
 */
class ProductVersion
{
    use ProductBase;
    /**
     * @ORM'ManyToOne(targetEntity="Product", inversedBy="auditLog")
     */
    private $product;
    /**
     * @ORM'Column(type="integer")
     */
    private $version;
    public function __construct(Product $product)
    {
        $this->product = $product;
        $this->name = $product->getName();
        $this->version = $product->getVersion();
        var_dump($product->getVersion());
    }
    // Version getter and setter
}

这是插入新条目并更新以创建新版本的代码：

// Insert new product
$this->entityManager->beginTransaction();
$this->entityManager->flush();
$product = new Product();
$product->setName('Product V1');
$this->entityManager->persist($product);
$this->entityManager->flush();
$this->entityManager->commit();
$productId = $product->getId();
echo "Created Product with ID " . $product->getId() . "'n";
/** @var Product $foo */
$foo = $this->entityManager->getRepository('orm'Product')->find($productId);
// Log version (Product V1)
$this->entityManager->beginTransaction();
$this->entityManager->flush();
$foo->logVersion();
$this->entityManager->flush();
$this->entityManager->commit();
// Update 1
$foo->setName('Product V2');
$this->entityManager->flush();
// Log version (Product V2)
$this->entityManager->beginTransaction();
$this->entityManager->flush();
$foo->logVersion();
$this->entityManager->flush();
$this->entityManager->commit();
// Update 2 
$foo->setName('Product V3');
$this->entityManager->flush();

模式生成

$tools = new SchemaTool($this->entityManager);
var_dump($tools->getCreateSchemaSql(array(
    $this->entityManager->getClassMetadata('orm'Product'),
    $this->entityManager->getClassMetadata('orm'ProductVersion')
)));

class Product
{
    private $auditLog;
    public function __construct()
    {
        $this->auditLog = new 'Doctrine'Common'Collections'ArrayCollection();
    }

class ProductVersion
{
    /** @ORM'ManyToOne(targetEntity="Product", inversedBy="auditLog") */
    private $product;

$ doctrine orm:validate-schema          // plain Doctrine2
