Symfony多实体管理器未发现错误

我有两个bundle主AppBundle和PrestaShopConnectionBundle从PrestaShop数据库获取信息。当我试图从ProductShop实体获取信息时，我得到了错误:

SQLSTATE[42S02]: Base table or view not found: 1146 Table 'prestashop.ps_product_shop' doesn't exist 

命令

php app/console doctrine:schema:update --dump-sql --em=prestashop

返回"Nothing to update"，所以它可能是从PrestaShop检测到的表。但是为什么控制器不能从中获取日期呢?

    protected $id;
