The WMSDoctrineExtendedRepositoriesBundle allows you to use dependency injection within Doctrine Repositories by registering them as services.

This document contains information on how to download, install and use this bundle.

  1. Installing the Bundle

Using Composer

As Symfony uses Composer to manage its dependencies, the recommended way to install this bundle is to use it.

If you don't have Composer yet, download it following the instructions on http://getcomposer.org/ or just run the following command:

curl -s http://getcomposer.org/installer | php

Then, use the require command to download this bundle:

php composer.phar require wms/doctrine-extended-repository-bundle:~1.0@dev

Finally, edit your AppKernel.php file and add the bundle:

  1. Usage

In order to create a repository, simply create a new class using the following template:

use Doctrine\ORM;

class MyCustomRepository extends EntityRepository {
	private $dep;

     * Initializes a new EntityRepository.
     * @param EntityManager         $em    The EntityManager to use.
     * @param Mapping\ClassMetadata $class The class descriptor.
     * @param MyDependency          $dep   The rest of the arguments are yours to choose!
	public function __construct($em, Mapping\ClassMetadata $class, MyDependency $dep) {
		parent::__construct($em, $class);

		$this->dep = $dep;

IMPORTANT: In order to be compatible with Doctrine repositories, the first two arguments of your repository are reserved to the entity manager and the ClassMetadata of your entity. These will be automatically injected.

Then, simply define your service:

**XML: **

<?xml version="1.0" ?>
<container xmlns="http://symfony.com/schema/dic/services"
    xsi:schemaLocation="http://symfony.com/schema/dic/services http://symfony.com/schema/dic/services/services-1.0.xsd">

        <service id="my_super_repository" class="MyCustomRepository">
            <argument type="service" id="my_dependency" />
			<tag name="wms.doctrine_extended_repository" entity="ACMEBundle:SuperEntity" connection="default" />

**YAML: **

		class: MyCustomRepository
		arguments: [ @my_dependency ]
			- { name: wms.doctrine_extended_repository, entity: "ACMEBundle:SuperEntity", connection: default }

You may omit the connection attribute on the tag. If so, it will use the default connection/entity manager.
