Configuring Doctrine ORM

Nice features a simplistic Doctrine ORM bridge that integrates the two, exposing a few useful services. Usage is straightforward: install the Doctrine ORM package and then configuration the extension.

First, add the Nice Doctrine ORM extension to your project. You can do this by updating your composer.json or running composer require at the command line.

• Example composer.json:

  {
      "require": {
          "nice/framework": "~1.0",
          "nice/doctrine-orm": "~1.0"
      }
  }

  Then run composer update at the command line.

• Using the composer command line tool

  composer require nice/doctrine-orm:~1.0

Once Doctrine ORM and the Nice extension are installed, open your front controller (usually web/index.php) and add the following:

use Nice\Extension\DoctrineOrmExtension;

// ...

$app = new Application();
$app->appendExtension(new DoctrineOrmExtension(array(
    'database' => array(
        'driver' => 'pdo_sqlite',
        'path' => '%app.root_dir%/sqlite.db'
    ),
    'mapping' => array(
        'default' => array(
            'driver' => 'annotation',        // Or xml, yml, or php
            'paths' => '%app.root_dir%/src', // Path to your entities or mapping files
            'namespace' => 'Example'
        ),
    ),
)));

Note: You will need to modify the namespace option in the above example to match your project.

You can specify multiple mapping drivers. Ensure each has a unique name and namespace prefix.

// ...
    'mapping' => array(
        'default' => array(
            'driver' => 'annotation',
            'paths' => '%app.root_dir%/src',
            'namespace' => 'Example\\Entity'
        ),
        'secondary' => array(
            'driver' => 'yml',
            'paths' => '%app.root_dir%/mapping',
            'namespace' => 'Awesome\\Entity'
        ),
    ),
)));

Two services are made available by the extension:

• doctrine.orm.entity_manager is the EntityManager. It is an instance of Doctrine\ORM\EntityManager.
• doctrine.orm.configuration is the Configuration instance for the database.
