Hi all, I would like if someone could clarify some points to me regarding the dependency container. I've successfully modified some stuff of the security component just adding a config.xml to my Resources/config dir. I've changed some parameters of the security component there. Then, in my app/config/config.yml I've imported my Resources/config/config.xml and everything went fine.
Now, I want to create a service of my own on one of my bundles. But I don't want to make the user import the config.xml from his/her app/config/config.yml. What I see everyone does is create a MyBundle/DependencyInjection/WhateverExtension.php, and automatically load the config there. So, with my new service, what I did es create again a simple Resources/config/config.xml that looks like this: <?xml version="1.0" encoding="UTF-8" ?> <container xmlns="http://www.symfony-project.org/schema/dic/services"; xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"; xsi:schemaLocation="http://www.symfony-project.org/schema/dic/services http://www.symfony-project.org/schema/dic/services/services-1.0.xsd";> <parameters> <parameter key="my_service.class">Bundle\MyBundle\ModuleManager\ModuleManager</parameter> </parameters> <services> <service id="my_service" class="%my_service.class%" /> </services> </container> Then, I create DependencyInjection/WhateverExtension.php class WhateverExtension extends Extension { public function configLoad( $config, ContainerBuilder $container ) { $loader = new XmlFileLoader( $container, __DIR__.'/../Resources/config' ); $loader->load( 'config.xml' ); } public function getXsdValidationBasePath() { return __DIR__.'/../Resources/config/schema'; } public function getNamespace() { return 'http://www.symfony-project.org/schema/dic/my_service'; } public function getAlias() { return 'my_service'; } } Finally, to get it work I had to add this to my app/config/config.yml my_service.config: ~ Then, my questions: 1) Is this the way to create a service that needs to get autoloaded, without import the xml file from the app/config/config.yml? If that's the case, Is this the shortest way to create a new service that gets autoloaded? 2) The getAlias method is the alias to get the service with $this->container->get( $myAlias ) ? 3) Which are the other uses the Extension class has, besides the fact that it gets autoloaded? For example, I saw a lot of other extensions (from some symfony bundles too) and it seems to provide a way to handle defaults for certain configs. 4) Any other point that you can tell me about this topic would be of great help. I saw the Dependency Injection docs (I'll have to see it again to refresh my knowledge :P), and I saw the part of this topic on the symfony 2 docs, but there're a few points that still don't know about it. I know that the documentation will be more and more complete within the next months, but if you can give me a few hints regarding this topic, I'd be very grateful :) Thanks and sorry for the long post. -- If you want to report a vulnerability issue on symfony, please send it to security at symfony-project.com You received this message because you are subscribed to the Google Groups "symfony developers" group.
