Question

我正在尝试使用doctrine创建迁移：migrations：diff。数据库现在已经处于足够好的状态，但是当我尝试某些东西（例如下面显示的名称）时，它也会不断尝试更改外键。

但它一直试图改变FK键：

    public function up(Schema $schema)
    {
    // this up() migration is auto-generated, please modify it to your needs
    $this->abortIf($this->connection->getDatabasePlatform()->getName() !== 'mysql', 'Migration can only be executed safely on \'mysql\'.');

    $this->addSql('ALTER TABLE order_manager ADD name VARCHAR(255) NOT NULL');
    $this->addSql('ALTER TABLE orders RENAME INDEX fk_e6ab879d9395c3f3 TO IDX_E52FFDEE9395C3F3');
    $this->addSql('ALTER TABLE orders RENAME INDEX fk_e6ab879dcbe4c936 TO IDX_E52FFDEECBE4C936');
    }

这是实体类：

class Orders extends BaseEntity
{ 
/**
 * @ORM\Id
 * @ORM\GeneratedValue
 * @ORM\Column(type="integer")
 */
private $id;

/**
 * @ORM\ManyToOne(targetEntity="App\Entity\Customer", inversedBy="orders", fetch="EAGER")
 * @ORM\JoinColumn(name="customer_id", nullable=true)
 */
private $customer;

/**
 * @ORM\ManyToOne(targetEntity="App\Entity\OrderManager", inversedBy="orders", fetch="EAGER")
 * @ORM\JoinColumn(name="order_manager_id", nullable=true)
 */
private $orderManager;

public function getId()
{
    return $this->id;
}

public function getCustomer(): Customer
{
    return $this->customer;
}

public function setCustomer(Customer $customer)
{
    $this->customer = $customer;
}

public function getOrderManager(): orderManager
{
    return $this->orderManager;
}

public function setOrderManager(orderManager $orderManager)
{
    $this->orderManager = $orderManager;
}
}

尝试做教义时：迁移：迁移我收到此错误

执行＆＃39; ALTER TABLE命令时发生异常RENAME INDEX fk_e6ab879d9395c3f3 TO IDX_E52FFDEE9395C3F3＆＃39;：

好像你手动添加了这些索引。您需要做的是使用name注释告诉您的索引的@ORM\Index。 http://docs.doctrine-project.org/projects/doctrine-orm/en/latest/reference/annotations-reference.html#annref-index

Doctrine迁移差异不断创建错误的信息
