【问题描述】:
您好,我从 Symfony2 文档中复制了使用两个不同数据库连接的示例:Symfony2 multiple connections documentation 因此,Symfony 没有找到客户实体管理器。 (参数定义正确)
doctrine:
dbal:
default_connection: default
connections:
default:
driver: "%database_driver%"
host: "%database_host%"
port: "%database_port%"
dbname: "%database_name%"
user: "%database_user%"
password: "%database_password%"
charset: UTF8
customer:
driver: "%database_driver%"
host: "%database_host2%"
port: "%database_port2%"
dbname: "%database_name2%"
user: "%database_user2%"
password: "%database_password2%"
charset: UTF8
orm:
default_entity_manager: default
entity_managers:
default:
connection: default
mappings:
AppBundle: ~
customer:
connection: customer
mappings:
AppBundle: ~
控制器看起来像这样:
class DefaultController extends Controller
{
/**
* @Route("/", name="homepage")
*/
public function indexAction(Request $request)
{
$em = $this->get('doctrine')->getManager();
$em = $this->get('doctrine')->getManager('default');
$em = $this->get('doctrine.orm.default_entity_manager');
// Both of these return the "customer" entity manager
$customerEm = $this->get('doctrine')->getManager('customer');
$customerEm = $this->get('doctrine.orm.customer_entity_manager');
return $this->render('default/index.html.twig', array(
'base_dir' => realpath($this->container->getParameter('kernel.root_dir').'/..'),
));
}
我应该得到客户实体管理器,但是 Symfony 会在消息中抛出一个无效参数异常。
[2015-10-19 23:19:18] request.CRITICAL: Uncaught PHP Exception
InvalidArgumentException: "Doctrine ORM Manager named "customer" does
not exist." at /srv/www/htdocs/symfony/my_project_name/app/cache
/prod/classes.php line 7344 {"exception":"[object]
(InvalidArgumentException(code: 0): Doctrine ORM Manager named
\"customer\" does not exist. at /srv/www/htdocs/symfony/my_project_name
/app/cache/prod/classes.php:7344)"} []
我用 php app/console cache:clear 清理了缓存,但这没有帮助。
【问题讨论】:
-
cache:clear默认清除dev环境,但查看错误日志,您会在prod环境中收到错误。要清除生产环境中的缓存,请添加-e prod标志,例如cache:clear -e prod并刷新您的页面。
