如何将服务注入Symfony 2 Data Fixtures？ [英] How to inject service into Symfony 2 Data Fixtures?

问题描述

如何将服务注入 Symfony2 / Doctrine2数据夹具 ？我想创建虚拟用户，并需要 security.encoder_factory 服务来对我的密码进行编码。

How can I inject a service into Symfony2/Doctrine2 Data Fixtures? I want to create dummy users and need the security.encoder_factory service to encode my passwords.

我尝试将数据夹具定义为服务

I tried defining my Data Fixture as a service

myapp.loadDataFixture:
    class: myapp\SomeBundle\DataFixtures\ORM\LoadDataFixtures
    arguments:
        - '@security.encoder_factory'

然后在我的数据夹具中

class LoadDataFixtures implements FixtureInterface {

    protected $passwordEncoder;

    public function __construct($encoderFactory) {
        $this->passwordEncoder = $encoderFactory->getEncoder(new User());
    }

    public function load($em) {

但是得到了类似的东西

警告：
缺少参数1 ... \DataFixtures\ORM\LoadDataFixtures :: __construct（），在...中调用。

Warning: Missing argument 1 for ...\DataFixtures\ORM\LoadDataFixtures::__construct(), called in ...

推荐答案

在灯具中使用容器部分确切说明了您的需求。

The Using the Container in the Fixtures section describes exactly what you need.

您需要做的就是在灯具中实现 ContainerAwareInterface 。这将导致Symfony通过Setter-Injection注入容器。示例实体看起来像这样：

All you need to do is to implement the ContainerAwareInterface in your fixture. This will cause the Symfony to inject the container via Setter-Injection. An example entity would look like this:

class LoadDataFixtures implements FixtureInterface, ContainerAwareInterface {

     /**
     * @var ContainerInterface
     */
    private $container;

    public function setContainer(ContainerInterface $container = null)
    {
        $this->container = $container;
    }

    public function load($em) {

您不需要将灯具注册为服务。确保通过 use 导入使用的类。

You don't need to register the fixture as a service. Make sure to import the used classes via use.
