This PR was merged into the 4.3-dev branch. Discussion ---------- [DependencyInjection] Add ability to define an index for service in an injected service locator argument | Q | A | ------------- | --- | Branch? | master | Bug fix? | no | New feature? | yes | BC breaks? | no | Deprecations? | no | Tests pass? | yes | Fixed tickets | n/a | License | MIT | Doc PR | in progress / symfony/symfony-docs#... It's more or less the same thing then the PR #30257 but for a service locator argument Add a simple way to specify an index based on a tag attribute to simplify retrieving a specific service when injecting a service locator as argument into services, but also a way to fallback to a static method on the service class. Yaml: ```yaml services: foo_service: class: Foo tags: - {name: foo_tag, key: foo_service} foo_service_tagged: class: Bar arguments: - !tagged_locator tag: 'foo_tag' index_by: 'key' default_index_method: 'static_method' ``` XML: ```xml <?xml version="1.0" ?> <container xmlns="http://symfony.com/schema/dic/services" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://symfony.com/schema/dic/services http://symfony.com/schema/dic/services/services-1.0.xsd"> <services> <service id="foo" class="Foo"> <tag name="foo_tag" key="foo_service" /> </service> <service id="foo_tagged_iterator" class="Bar" public="true"> <argument type="tagged_locator" tag="foo_tag" index-by="key" default-index-method="static_method" /> </service> </services> </container> ``` PHP: ```php // config/services.php use Symfony\Component\DependencyInjection\Argument\TaggedIteratorArgument; use Symfony\Component\DependencyInjection\Argument\ServiceLocatorArgument; $container->register(Foo::class) ->addTag('foo_tag', ['key' => 'foo_service']); $container->register(App\Handler\HandlerCollection::class) // inject all services tagged with app.handler as first argument ->addArgument(new ServiceLocatorArgument(new TaggedIteratorArgument('app.handler', 'key'))); ``` Usage: ```php // src/Handler/HandlerCollection.php namespace App\Handler; use Symfony\Component\DependencyInjection\ServiceLocator; class HandlerCollection { public function __construct(ServiceLocator $serviceLocator) { $foo = $serviceLocator->get('foo_service'): } } ``` Tasks * [x] Support PHP loader/dumper * [x] Support YAML loader/dumper * [x] Support XML loader/dumper (and update XSD too) * [x] Add tests * [x] Documentation Commits ------- |
