为FOSUserBundle动态更改服务参数值

Question

我之前询问过为FOSUserBundle使用多个实体管理器,事实证明FOSUserBundle已经(部分)支持了它.所有我需要做的是指定连接/经理,我想在使用model_manager_name参数,如解释在这里

fos_user:
# ........
    model_manager_name: account1

示例app/config/config.yml

使用此FOSUserBundle将使用account1连接,并在该连接的数据库中使用用户信息.

doctrine:
dbal:
    default_connection:       default
    connections:
    account2:
        dbname:           account2
        user:             account2
        password:         password2
        driver:   pdo_mysql
        host:     localhost
        port:     ~
        charset:  UTF8
    account1:
        dbname:           account1
        user:             account1
        password:         password1
        driver:   pdo_mysql
        host:     localhost
        port:     ~
        charset:  UTF8
    default:
        dbname:           account
        user:             account
        password:         password
        driver:   pdo_mysql
        host:     localhost
        port:     ~
        charset:  UTF8

我的应用程序要求当用户访问(例如)http://myapp.com/a/account1时,应用程序将使用account1连接,并且转到http://myapp.com/a/account2将使用account2的连接.对于我的应用程序的逻辑,这可以通过我的控制器轻松完成,因为我可以使用类似下面的内容;

$em = $this->get('doctrine')->getManager('account2');
$repository = $this->get('doctrine')->getRepository($class, 'account2')

对于登录部分,它并不那么容易.FOSUserBundle作为服务容器运行,我不知道在何处/如何动态更改其model_manager_name值.我知道虽然FOS\UserBundle\DependencyInjection\FOSUserExtension我可以通过以下方式手动更改其值;

class FOSUserExtension extends Extension
{
public function load(array $configs, ContainerBuilder $container)
{
    $processor = new Processor();
    $configuration = new Configuration();

    $config = $processor->processConfiguration($configuration, $configs);

    $config['model_manager_name'] = 'account2';
    // .................

有什么想法吗？

配置存储在容器内,fos_user.model_manager_name确切地说.

您可以编写编译器传递.这将在冻结容器之前执行,它是您可以更改容器的最后一个位置,它是根据其他服务更改容器的位置.

您的编译器传递将如下所示:

// src/Acme/DemoBundle/DependencyInjection/Compiler/ChangeModelManagerPass.php
namespace Acme\DemoBundle\DependencyInjection\Compiler;

use Symfony\Component\DependencyInjection\Compiler\CompilerPassInterface;
use Symfony\Component\DependencyInjection\ContainerBuilder;

class ChangeModelManagerPass implements CompilerPassInterface
{
    public function process(ContainerBuilder $container)
    {
        $request = $container->get('request');
        $uri = $request->getUri();

        // check if the uri matches some pattern which will cause a change in the
        // `model_manager_name` setting
        if (...) {
            // ... do some stuff to get the correct model manager name

            // set the setting
            $container->setParameter('fos_user.model_manager_name', ...);
        }
    }
}
