README

This is a replacement for the default repository structure of Doctrine ORM. This replacement implements a plugin architecture for extensisons to repositories.

For instance, if you need access to an encryption/decryption resource inside your repository you could implement it as a plugin accessible as

$this->plugin('encryption')->encrypt($value);

Why use this repository structure?

The default repository for Doctrine ORM gives no access to resources outside Doctrine. And the Doctrine ORM Object Manager does not give access to a dependency injection container. So when your applications require more from their repositories the only option is to write your own dependency injection enabled repository factory. To create a standard way to organize this dependency injection repository factory: this is an acceptable solution.

Installation

Installation of this module uses composer. For composer documentation, please refer to getcomposer.org.

$ composer require api-skeletons/zf-doctrine-repository

Once installed, add ZF\Doctrine\Repository to your list of modules inside config/application.config.php or config/modules.config.php.

zf-component-installer

If you use zf-component-installer, that plugin will install zf-doctrine-repository as a module for you.

Configuration

No manual configuration is required to use this module.

This module makes these changes to your doctrine.entitymanager.orm_default configuration:

namespace ZF\Doctrine\Repository;
...
    'doctrine' => [
        'configuration' => [
            'orm_default' => [
                'repository_factory' => RepositoryFactory::class,
                'default_repository_class_name' => ObjectRepository::class,
            ],
        ],
    ],

If your application already has a default repository class you can edit it to implement ZF\Doctrine\Repository\ObjectRepositoryInterface and the RepositoryFactory can use it.

Creating a Plugin

The config key for the repository plugin service locator is zf-doctrine-repository-plugin. Your plugin must implement ZF\Doctrine\Repository\Plugin\PluginInterface

The __construct of your Plugin will take an array including the repository and any other parameters. Access to the repository gives you access to the ObjectManager.

Use the testing boolean plugin and testing boolean plugin configuration as a template.

Available Plugins

zf-doctrine-repository-query-provider - zfcampus/zf-apigility-doctrine includes Query Providers which may take the current authenticated user and add complex filters to a a QueryBuilder object in order to filter whether the user has access to a given entity. This filtering mechanism can be used across a whole application whenever authorized access is needed to an entity.

use Database\Entity\User;

// Return a single User entity fetched by applying the User Query Provider to a given `$id`
$objectManager->getRepository(User::class)->plugin('queryProvider')->find($id);

Future Plugin Plans

This repository is forward-looking and architected to support the needs today and into the future. Here are examples of repository plugins to be developed:

zf-doctrine-repository-audit - A trigger-happy application will create a structure of triggers on all tables accessible as Doctrine entities. Data would be accessible directly or to access the audit data with a plugin:

use Database\Entity\User;

// Return the date an entity was created using the audit trail.
$objectManager->getRepository(User::class)->plugin('audit')->getCreatedAt(User $userEntity);

// Return the date an entity was last modified using the audit trail.
$objectManager->getRepository(User::class)->plugin('audit')->getUpdatedAt(User $userEntity);

// Return the complete audit trail for an entity
$objectManager->getRepository(User::class)->plugin('audit')->getAuditTrail(User $userEntity);
