如何从控制器以编程方式添加学说实体管理器？

Question

我有一个控制器方法，我在其中以编程方式向 config.yml 添加了学说连接和学说实体管理器。

当我尝试获取刚刚通过 $doctrine->getManager('newManagerNameAdded') 添加的实体管理器时，Doctrine 告诉我该实体管理器不存在。

我认为有必要指定 doctrine 来重新加载它的配置，但我找不到这样做的方法。

有人做过吗？

在 config.yml 中将实体管理器添加到学说配置后，我尝试创建一个 cache:clear，但没有成功。

另一方面，如果我执行两次我的控制器方法，第二次 doctrine 知道如何恢复第一次在配置中添加的实体管理器。

$configArray = Yaml::parseFile($this->configFilePath);

// Si la connection n'existe pas, on l'ajoute
if (!array_key_exists($entityManagerName, $configArray["doctrine"]["orm"]["entity_managers"])) {
    $configArray["doctrine"]["orm"]["entity_managers"][$entityManagerName] = array(
                "connection" => $entityManagerName,
                "mappings" => array("AppBundle" => null),
            );
        }

$yamlUpdated = Yaml::dump($configArray);

file_put_contents($this->configFilePath, $yamlUpdated);

$this->doctrine->getManager($entityManagerName); // This throw an exception 'Doctrine entity manager named $connectionName does not exist'

这是 doctrine.yaml 文件：

doctrine:
  dbal:
    default_connection: core
    connections:
      core:
        driver: pdo_pgsql
        host: '%core_database_host%'
        port: '%core_database_port%'
        dbname: '%core_database_name%'

        mappings:

        dql:

      customer2:

        mappings:
          AppBundle: null

我创建了解决方案。

我将新的连接和实体管理器添加到 doctrine.yml 配置文件，并在我的控制器操作中通过学说 API 创建了一个实体管理器。

这是解决我问题的代码。

// STEP 1: Update doctrine.yml for add connection and entity manager
$configArray = Yaml::parseFile($this->configFilePath.'doctrine.yml');
$configArray["doctrine"]["dbal"]["connections"][$connectionName] = array(
            "driver" => "pdo_pgsql",
            "host" => '127.0.0.1',
            "port" => '5432',
            "dbname" => $databaseName,
            "user" => $databaseUsername,
            "password" => $databaseUserPassword,
            "charset" => "utf8"
        );
$configArray["doctrine"]["orm"]["entity_managers"][$connectionName] = array(
                "connection" => $connectionName,
                "mappings" => array("AppBundle" => null),
                "dql" => array("datetime_functions" => array("date_format" => "DoctrineExtensions\Query\Postgresql\DateFormat"))
            );
$yamlUpdated = Yaml::dump($configArray);
file_put_contents($this->configFilePath.'doctrine.yml', $yamlUpdated);

// STEP 2 : Create new entity manager via Doctrine APIs
$config = Setup::createAnnotationMetadataConfiguration(array($this->getParameter('kernel.project_dir'). DIRECTORY_SEPARATOR ."/src/AppBundle/Entity"), false, null, null, false);

$em = EntityManager::create(array(
            "driver" => "pdo_pgsql",
            "host" => '127.0.0.1',
            "port" => '5432',
            "dbname" => $databaseName,
            "user" => $databaseUsername,
            "password" => $databaseUserPassword,
            "charset" => "utf8"
        ), $config);

// STEP 3 : Create database schema
$metadata = $em->getMetadataFactory()->getAllMetadata();
$tool = new SchemaTool($em);
$tool->createSchema($metadata);

// STEP 4 : Make what do you want with the new entitymanager
