Extra goodies included with DoctrineModule

The items listed below are entirely optional and are intended to enhance integration between Zend Framework 2 and Doctrine 2 .

ObjectExists and NoObjectExists Validators

The ObjectExists and NoObjectExists are validators similar to Zend\Validator\Db validators. You can pass a variety of options to determine validity. The most basic use case requires an entity manager (em), an entity, and a field. You also have the option of specifying a query_builder Closure to use if you want to fine tune the results.

<?php
$validator = new \DoctrineModule\Validator\NoObjectExists(array(
    // object repository to lookup
    'object_repository' => $serviceLocator->get('Doctrine\ORM\EntityManager')->getRepository('My\Entity\User'),

    // fields to match
    'fields' => array('username'),
));

// following works also with simple values if the number of fields to be matched is 1
echo $validator->isValid(array('username' => 'test')) ? 'Valid' : 'Invalid! Duplicate found!';

Authentication adapter for Zend\Authentication

The authentication adapter is intended to provide an adapter for Zend\Authentication. It works much like the DbTable adapter in the core framework. You must provide the entity manager instance, entity name, identity field, and credential field. You can optionally provide a callable method to perform hashing on the password prior to checking for validation.

<?php
$adapter = new \DoctrineModule\Authentication\Adapter\DoctrineObject(
    $this->getLocator()->get('Doctrine\ORM\EntityManager'),
    'Application\Test\Entity',
    'username', // optional, default shown
    'password',  // optional, default shown,
    function($identity, $credential) { // optional callable
        return \My\Service\User::hashCredential(
            $credential,
            $identity->getSalt(),
            $identity->getAlgorithm()
        );
    }
);

$adapter->setIdentityValue('admin');
$adapter->setCredentialValue('pa55w0rd');
$result = $adapter->authenticate();

echo $result->isValid() ? 'Authenticated!' : 'Could not authenticate';

Custom DBAL Types

To register custom Doctrine DBAL types, simply add them to the doctrine.configuration.my_dbal_default.types key in you configuration file:

<?php
return array(
    'doctrine' => array(
        'configuration' => array(
            'my_dbal_default' => array(
                'types' => array(
                    // You can override a default type
                    'date' => 'My\DBAL\Types\DateType',

                    // And set new ones
                    'tinyint' => 'My\DBAL\Types\TinyIntType',
                ),
            ),
        ),
    ),
);

You are now able to use them, for example, in your ORM entities:

<?php

class User
{
    /**
     * @ORM\Column(type="date")
     */
    protected $birthdate;

    /**
     * @ORM\Column(type="tinyint")
     */
    protected $houses;
}

To have Schema-Tool convert the underlying database type of your new "tinyint" directly into an instance of TinyIntType you have to additionally register this mapping with your database platform.

<?php
return array(
    'doctrine' => array(
        'connection' => array(
            'orm_default' => array(
                'doctrine_type_mappings' => array(
                    'tinyint' => 'tinyint',
                ),
            ),
        ),
    ),
);

Now using Schema-Tool, whenever it detects a column having the "tinyint" it will convert it into a "tinyint" Doctrine Type instance for Schema representation. Keep in mind that you can easily produce clashes this way, each database type can only map to exactly one Doctrine mapping type.

Something went wrong with that request. Please try again.
