psr-container-doctrine: Doctrine Factories for PSR-11 Containers

Doctrine factories for PSR-11 containers.

This package provides a set of factories to be used with containers using the PSR-11 standard for an easy Doctrine integration in a project. This project was originally written by @DASPRiD but maintenance has been taken over by Roave.

Installation

The easiest way to install this package is through composer:

$ composer require roave/psr-container-doctrine

Configuration

In the general case where you are only using a single connection, it's enough to define the entity manager factory:

return [
    'dependencies' => [
        'factories' => [
            'doctrine.entity_manager.orm_default' => \Roave\PsrContainerDoctrine\EntityManagerFactory::class,
        ],
    ],
];

If you want to add a second connection, or use another name than "orm_default", you can do so by using the static variants of the factories:

return [
    'dependencies' => [
        'factories' => [
            'doctrine.entity_manager.orm_other' => [\Roave\PsrContainerDoctrine\EntityManagerFactory::class, 'orm_other'],
        ],
    ],
];

You can also define an alias to retrieve an entity manager instance using ::class capability:

return [
    'aliases' => [
        'doctrine.entity_manager.orm_default' => Doctrine\ORM\EntityManagerInterface::class,
    ],
];

Each factory supplied by this package will by default look for a registered factory in the container. If it cannot find one, it will automatically pull its dependencies from on-the-fly created factories. This saves you the hassle of registering factories in your container which you may not need at all. Of course, you can always register those factories when required. The following additional factories are available:

\Roave\PsrContainerDoctrine\CacheFactory (doctrine.cache.*)
\Roave\PsrContainerDoctrine\ConnectionFactory (doctrine.connection.*)
\Roave\PsrContainerDoctrine\ConfigurationFactory (doctrine.configuration.*)
\Roave\PsrContainerDoctrine\DriverFactory (doctrine.driver.*)
\Roave\PsrContainerDoctrine\EventManagerFactory (doctrine.event_manager.*)

Each of those factories supports the same static behavior as the entity manager factory. For container specific configurations, there are a few examples provided in the example directory:

Example configuration

A complete example configuration can be found in example/full-config.php. Please note that the values in there are the defaults, and don't have to be supplied when you are not changing them. Keep your own configuration as minimal as possible. A minimal configuration can be found in example/minimal-config.php

Migrations

If you want to expose the migration commands, you have to map the command name to CommandFactory. This factory needs migrations config setup. For ExecuteCommand example:

return [
    'dependencies' => [
        'factories' => [
            \Doctrine\Migrations\Tools\Console\Command\ExecuteCommand::class => \Roave\PsrContainerDoctrine\Migrations\CommandFactory::class,

            // Optionally, you could make your container aware of additional factories as of migrations release v3.0:
            \Doctrine\Migrations\Configuration\Migration\ConfigurationLoader::class => \Roave\PsrContainerDoctrine\Migrations\ConfigurationLoaderFactory::class,
            \Doctrine\Migrations\DependencyFactory::class => \Roave\PsrContainerDoctrine\Migrations\DependencyFactoryFactory::class,
        ],
    ],
];

You can find a full list of available commands in example/full-config.php.

Using the Doctrine CLI

In order to be able to use the CLI tool of Doctrine, you need to set-up a cli-config.php file in your project directory. That file is generally quite short, and should look something like this for you:

<?php
$container = require 'config/container.php';

return \Doctrine\ORM\Tools\Console\ConsoleRunner::createHelperSet(
    $container->get('doctrine.entity_manager.orm_default')
);

After that, you can simply invoke php vendor/bin/doctrine.

Multiple connections

It gets a little trickier when you have multiple entity managers. Doctrine itself has no way to handle that itself, so a possible way would be to have two separate directories with two unique cli-config.php files. You then invoke the doctrine CLI from each respective directory. Since the CLI is looking for the config file in the current working directory, it will then always use the one from the directory you are currently in.

The following code can be used for multiple connections, but it got the drawback, that you won't see the --em=... option within the help section of each command.

<?php
$container = require 'config/container.php';

$input = new \Symfony\Component\Console\Input\ArgvInput();

/** @var string $em */
$em = $input->getParameterOption('--em', 'orm_default');

// hack to remove the --em option, cause it's not supported by the original ConsoleRunner.
foreach ($_SERVER['argv'] as $i => $arg) {
    if (0 === strpos($arg, '--em=')) {
        unset($_SERVER['argv'][$i]);
    }
}

try {
    $entityManager = $this->container->get('doctrine.entity_manager.'.$em);
} catch (\Psr\Container\NotFoundExceptionInterface $serviceNotFoundException) {
    throw new \InvalidArgumentException(sprintf('Missing entity manager with name "%s"', $entityManagerName));
}

return \Doctrine\ORM\Tools\Console\ConsoleRunner::createHelperSet($entityManager);
