[英]How to extend config of different bundle in Symfony2?
I know I can overwrite templates or extend classes of other bundles. 我知道我可以覆盖模板或扩展其他包的类。 But can I extend also configs?
但我可以延长配置吗? I was hoping to be able to load other namespaces from config in
DependenyInjection/AcmeExtension.php
's load method, but I haven't found anything about it anywhere. 我希望能够在
DependenyInjection/AcmeExtension.php
的加载方法中从config加载其他命名空间,但我在任何地方都没有找到任何关于它的信息。
Example: 例:
I have AcmeBundle which defines following in config: 我有AcmeBundle,它在config中定义了以下内容:
acme:
a: 1
I want to extend this bundle (in new bundle called AwesomeAcmeBundle) and be able to define another variables either by adding them to original namespace: 我想扩展这个包(在名为AwesomeAcmeBundle的新包中)并能够通过将它们添加到原始命名空间来定义另一个变量:
acme:
a: 1
b: 2
or by wrapping original namespace to new one and adding new variables there: 或者通过将原始名称空间包装到新名称空间并在其中添加新变量
awesome_acme:
a: 1
b: 2
I had similar needs and I have solved them in the following way: 我有类似的需求,我已通过以下方式解决了这些问题:
1) Extend the parent's Configuration class 1)扩展父的Configuration类
//FooBundle\DependencyInjection\Configuration.php
use DerpBundle\DependencyInjection\Configuration as BaseConfiguration;
class Configuration extends BaseConfiguration
{
public function getConfigTreeBuilder()
{
$treeBuilder = parent::getConfigTreeBuilder();
//protected attribute access workaround
$reflectedClass = new \ReflectionObject($treeBuilder);
$property = $reflectedClass->getProperty("root");
$property->setAccessible(true);
$rootNode = $property->getValue($treeBuilder);
$rootNode
->children()
...
return $treeBuilder;
}
}
2) Create own extension that actually can handle the new configuration entries 2)创建实际可以处理新配置条目的自己的扩展
class FooExtension extends Extension
{
public function load(array $configs, ContainerBuilder $container)
{
$configuration = new Configuration();
$config = $this->processConfiguration($configuration, $configs);
//custom parameters
$container->setParameter('new_param_container_name', $config['new_param_name']);
...
}
}
3) in the app\\config\\config.yml
you can use in your new foo
attribute-set all the parameters that derp
(as a parent bundle) has plus any of your new params that you have defined in the Configuration.php
. 3)在
app\\config\\config.yml
你可以在你的新foo
属性中使用 - 设置derp
(作为父包)的所有参数以及你在Configuration.php
定义的任何新参数。
imports:
- { resource: @YourBundle/Resources/config/services.yml }
If you're talking about the .yml
s, you can import the AcmeBundle
s confing in the AwesomeAcmeBundle
config with 如果你在谈论
.yml
,你可以在AwesomeAcmeBundle
配置中导入AcmeBundle
s confing
imports:
- { resource: path/to/AcmeBundles/config.yml }
and then overwrite the parameters you want. 然后覆盖您想要的参数。
Symfony is doing the same in the config_dev.yml
with the framework/router
parameter. Symfony在
config_dev.yml
使用framework/router
参数执行相同的操作。
