Simple Doctrine Mapping for Symfony2

KISS, Remember?

This project provides you an amazing way of adding your entities mapping data in any Symfony project, without the need of taking part of the auto_mapping doctrine process.

With a simple compiler pass in your bundle, make sure your entities are mapped properly into database, and provider your bundle users a unique way of overwriting and customization of these entities.

To work with a higher abstraction level of this bundle, use the mapping part of http://github.com/mmoreram/BaseBundle. This bundle makes the best possible integration of SimpleDoctrineMapping in your bundles.

Repeat with me, Keep it simple.

CompilerPass

For those of you who still do not know what is a CompilerPass, try to visualize it as your last chance to configure your container. At this point you can retrieve all your parameter configuration, but you cannot build any service, this is the point where you can dynamically build and complete services.

Once compiled, this container will be read-only.

This CompilerPass let each bundle be responsible for its own entities, defining per each one, the class to be mapped, the path of the mapping file and the manager that will manage it.

You should create your own compiler pass

<?php

/**
 * SimpleDoctrineMapping for Symfony2
 */

namespace TestBundle\CompilerPass;

use Symfony\Component\DependencyInjection\ContainerBuilder;

use Mmoreram\SimpleDoctrineMapping\CompilerPass\Abstracts\AbstractMappingCompilerPass;

/**
 * Class MappingCompilerPass
 */
class MappingCompilerPass extends AbstractMappingCompilerPass
{
    /**
     * You can modify the container here before it is dumped to PHP code.
     *
     * @param ContainerBuilder $container
     *
     * @api
     */
    public function process(ContainerBuilder $container)
    {
        $this
            ->addEntityMapping(
                $container,
                'default',
                'TestBundle\Entity\User',
                '@TestBundle/Mapping/User.orm.yml',
                true
            )
        ;
    }
}

and add it into the Container. Like this:

    <?php

    /**
     * SimpleDoctrineMapping for Symfony2
     */

    namespace Mmoreram\SimpleDoctrineMapping\Tests\Functional\TestBundle;

    use Symfony\Component\DependencyInjection\ContainerBuilder;
    use Symfony\Component\HttpKernel\Bundle\Bundle;

    use Mmoreram\SimpleDoctrineMapping\Tests\Functional\TestBundle\CompilerPass\MappingCompilerPass;

    /**
     * Class TestBundle
     */
    class TestBundle extends Bundle
    {
        /**
         * @param ContainerBuilder $container
         */
        public function build(ContainerBuilder $container)
        {
            $container->addCompilerPass(new MappingCompilerPass());
        }
    }

And that's it. After the container compilation it will add our mapping information. No magic.

addEntityMapping()

The method addEntityMapping() does not offer us many options, but the necessary to be able to define the entity map in most cases.

    /**
     * Add mapping entity
     *
     * This method adds a new Driver into global MappingDriverChain with single
     * entity mapping information.
     *
     * $entityManagerName must be an existing entityManager. By default doctrine
     * creates just one common EntityManager called default, but many can be
     * defined with different connection information
     *
     * p.e. default
     * p.e. anotherEntityManager
     *
     * $entityNamespace must be an existing namespace of Entity. This value also
     * can be a valid and existing container parameter, with an existing
     * namespace of an Entity as value.
     *
     * p.e. MyBundle\Entity\User
     * p.e. mybundle.entity.user.class
     *
     * $entityMappingFilePath must be a path of an existing yml or xml file with
     * mapping information about $entityNamespace. This bundle uses Short Bundle
     * notation, with "@" symbol. This value also can be a valid and existing
     * container parameter, with a path to an existing yml or xml file as value.
     *
     * p.e. @MyBundle/Resources/config/doctrine/User.orm.yml
     * p.e. @MyBundle/Resources/config/doctrine/User.orm.xml
     * p.e. mybundle.entity.user.mapping_file_path
     *
     * Finally, $enable flag just allow you to add current mapping definition
     * into all Doctrine Map table, or just dismiss it. This is useful when you
     * want to give possibility to final user to enable or disable a mapping
     * class.
     *
     * @param ContainerBuilder $container             Container
     * @param string           $entityManagerName     EntityManager name
     * @param string           $entityNamespace       Entity namespace
     * @param string           $entityMappingFilePath Entity Mapping file path
     * @param boolean          $enable                Entity mapping must be included
     *
     * @return $this self Object
     *
     * @throws EntityManagerNotFound Entity Manager not found
     */
    protected function addEntityMapping(
        ContainerBuilder $container,
        $entityManagerName,
        $entityNamespace,
        $entityMappingFilePath,
        $enable = true
    )

Of course, all values are required but the last one.

Parameters

So, imagine that you are working in a public Bundle, I mean, your bundle will be installed by other projects in their vendor folder, but you want to expose your own entity model.

You could think that by using this bundle you force the final user to use your model implementation in all cases, but is not.

If you want to give this power to your users, if you want to expose overridable entities, you can define your model using container parameters.

parameters:

    #
    # Mapping information
    #
    test_bundle.entity.user.class: "TestBundle\Entity\User"
    test_bundle.entity.user.mapping_file_path: "@TestBundle/Mapping/Class.orm.yml"
    test_bundle.entity.user.entity_manager: default
    test_bundle.entity.user.enable: true

In that case your bundle will put at users mercy the ability to override all the required parameters by just overriding specific configuration items.

You must finally create these params with your default values.
