CodeIgniter 2 + HMVC + Doctrine 2

Setup ready to use CodeIgniter framework with:

• CodeIgniter 2.1
• Modular Extensions - HMVC
• Doctrine 2.0
• DoctrineExtensions (partial support)

How to use?

Configuration

Set up application/config/config.php and application/config/database.php for your network.

Load Doctrine library adding it on autoload.php, example:

$autoload['libraries'] = array('doctrine');

Or load Doctrine library in any controller, example:

$this->load->library('doctrine');

Creating models

This setup uses docblock annotations mapping driver and models namespace, you can change it in application/libraries/Doctrine.php.

Example of root model (not in a module), it should be inside application/models:

namespace models;

/**
 * @Entity
 * @Table(name="users")
 */
class User {
	/**
	 * @Id
	 * @Column(type="integer")
	 * @GeneratedValue
	 */
	private $id;

	/**
	 * @Column(type="string", length=32, nullable=false)
	 */
	private $username;
	
	// ...
}

Example of model in a module, it should be inside application/[module_name]/models. Note the difference in namespace:

// Prototype:
// namespace [module_name]\models;
// Example:
namespace auth\models;

class User {
	/**
	 * @Id
	 * @Column(type="integer")
	 * @GeneratedValue
	 */
	private $id;

	/**
	 * @Column(type="string", length=32, nullable=false)
	 */
	private $username;
	
	// ...
}

Creating schemas

To generate automatically schemas for your models you can use the Doctrine console or the schema tool from library:

$this->doctrine->tool->createSchema('auth\models\User');

Other useful methods:

$this->doctrine->tool->dropSchema('auth\models\User');

$this->doctrine->tool->updateSchema('auth\models\User');

Using models

Loading from controllers it's easy, example:

$user = new auth\models\User;
// ...
$this->doctrine->em->persist($user);

You can also shorten the instantiation with the use operator (before class definition):

use auth\models\User;

class Test extends CI_Controller {
	// ...
	
	public function index()
	{
		$user = new User;
		// ...
	}
}

Doctrine console

Doctrine console can be used in terminal from application/third_party/doctrine-orm/bin/doctrine, examples:

php doctrine list

php doctrine orm:schema-tool:create

php doctrine orm:schema-tool:update

php doctrine orm:schema-tool:drop
