Doctrine custom hydrators with Zend Framework 2 - How to specify in config file?

Question

I've successfully created a custom Doctrine Hydrator, and can use it by calling the

$entityManager->getConfiguration()->addCustomHydrationMode('...', '...')

method.

However, I'm injecting dependencies into constructors via factories, so the entity manager isn't available in the classes themselves - which makes inheritance a bit more annoying (factory inheritance anyone?).

What I would prefer is to be able to configure my custom hydrators in the zf2 config file (where all the routes, services, other doctrine stuff etc is configured) - but I can't find any documentation on how to specify this.

1. Is this even possible?
2. What are the magic incantations necessary?

Cheers

Answer 1

It's possible to register hydrators in doctrine via configuration. For example to register the DoctrineModule\\Stdlib\\Hydrator\\DoctrineObject hydrator, in your module configuration array which is loaded by Application\\Module::getConfig you can add the following code.

'doctrine' => array(
    'configuration' => array(
        'orm_default' => array(
            'customHydrationModes' => array(
                'DoctrineModule' => 'DoctrineModule\Stdlib\Hydrator\DoctrineObject',
            ),
        ),
    ),
),

This registers DoctrineModule\\Stdlib\\Hydrator\\DoctrineObject under an hydration mode called DoctrineModule . Now you can obtain this hydrator from the entity manager.

$entityManager->newHydrator('DoctrineModule');

For more information about the DoctrineModule see https://github.com/doctrine/DoctrineModule/blob/master/docs/hydrator.md .

Found the way to specify custom doctrine hydrators in the config file:

['doctrine']['configuration']['orm_default']['customHydrationModes']

From the class docs (\\DoctrineORMModule\\Options\\Configuration):

Keys must be the name of the custom hydration method and the value must be the class name for the custom hydrator
