我在更新DiscriminatorColumn名称
时遇到问题实体：
/**
*@ORM\Entity
*@ORM\Table(name="item")
*@ORM\InheritanceType("JOINED")
*@ORM\DiscriminatorColumn(name="item_type", type="string")
*/
abstract class Item
{
}
/**
*@ORM\Entity
*@ORM\Table(name="product")
*@ORM\InheritanceType("JOINED")
*/
abstract class Product extends Item
{
}
/**
*@ORM\Entity
*@ORM\Table(name="vehicle")
*@ORM\InheritanceType("JOINED")
*/
abstract class Vehicle extends ItemBundle\Product
{
}
/**
*@ORM\Entity(repositoryClass="Aussiito\Bundles\VehicleBundle\Entity\Repository\CarRepository")
*@ORM\Table(name="car")
*/
class Car extends Vehicle
{
}
class CarRepository extends EntityRepository
{
public function getListCars(){
return $this->findAll();
}
}
在我没有添加注释之前：@ORM \ DiscriminatorColumn（name =＆＃34; item_type＆＃34;，type =＆＃34; string＆＃34;）on＆＃34; Item＆＃34; ，所以默认我有列dType。我想用＆＃34;重命名这些字段。 item_type＆＃34;所以我添加了注释并执行以下命令：
php bin/console doctrine:schema:update
数据库的修改已成功执行但当我调用函数getListCars（）时，出现以下错误：
执行＆＃39; SELECT t3.id AS id_4时发生异常，t3.created_at AS created_at_5，t3.updated_at AS updated_at_6，t2.id AS id_7，t1.id AS id_8，t0.id AS id_9，t3 .dtype FROM car t0 INNER JOIN vehicle t1 ON t0.id = t1.id INNER JOIN product t2 ON t0.id = t2.id INNER JOIN item t3 ON t0.id = t3.id＆＃39;：
SQLSTATE [42S22]：未找到列：1054未知列＆t 39.dtype＆＃39;在＆＃39;字段列表＆＃39;
所以我认为这是缓存，我执行了以下命令：
php bin/console cache:clear --env=prod
php bin/console cache:clear --env=dev
php bin/console doctrine:cache:clear-query
php bin/console doctrine:cache:clear-result
php bin/console doctrine:cache:clear-metadata
但我有同样的错误。
任何人都有解决方案吗？
