从另一个包修改包配置 [英] Modify bundle configuration from another bundle

问题描述

我想知道是否可以从另一个包修改包配置.比方说，例如，我正在使用具有以下配置的 FOSUserBundle:

I was wondering whether there's a possible to modify a bundles configuration from another bundle. Let's say, for example, I'm using the FOSUserBundle with the following configuration:

fos_user:
    db_driver: orm
    firewall_name: main
    user_class: AcmeUserBundleEntityUser

现在，我想在加载特定扩展(AcmeFoobarExtension)时更改用户类.加载时是否可以更改配置AcmeFoobarExtension?例如:

And now, I want to change the user class when loading a specific extension (the AcmeFoobarExtension). Is it possible to change the configuration when loading the AcmeFoobarExtension? For example:

<?php
namespace AcmeFoobarBundleDependencyInjection;

// use statements for dependency injection

class FoobarExtension extends Extension
{
    public function load(array $configs, ContainerBuilder $container)
    {
        $container->setConfiguration(
            'fos_user.user_class',
            'AcmeFoobarBundleEntityUser'
        );
    }
}

这样的事情可能吗?还是破坏了依赖注入的目的?

Is something like this possible? Or defeats it the purpose of dependency injection?

显然 Symfony 2.2 有一个 pull request 解决了这个想法/问题.

Apparently there's a pull request for Symfony 2.2 which addresses this idea/issue.

编辑 2:现在在 Symfony 2.2 中可用(在 文章中食谱).

EDIT 2: This is now available in Symfony 2.2 (with an article in the cookbook).

推荐答案

需要注意的是，现在这是 Symfony 的官方功能:

It should be noted that this is now an official feature of Symfony:

http://symfony.com/doc/current/cookbook/bundles/prepend_extension.html

bundle 可以将配置值添加到全局配置参数中.为此，捆绑扩展必须实现 PrependExtensionInterface.prepend() 方法然后可以添加全局配置值.

A bundle can prepend configuration values to the global config parameters. To do that, the bundle extension must implement PrependExtensionInterface. The prepend() method can then add global configuration values.

但是请注意，这些值可能会被其他包和配置文件本身覆盖.

Note, however, that the values may be overwritten by other bundles and in the config file itself.
