Provides the possibility to extend DiscriminatorMap on an Inheritance Mapped class with Class Table Inheritance in Symfony2 with Doctrine ORM 2.

This bundle was intended to extend an existing DiscriminatorMap (comes from any mapping) through the config file, if you can't do it by hand (ie: the bundle you want to extend is developed outside your project).

Installation

1, Using composer

1.1 Add netpositive/discriminatormapbundle to your composer.json

// composer.json
{
"require": {
    ...
    "netpositive/discriminatormap-bundle": "dev-master"

1.2 Enable it at your kernel

// app/AppKernel.php
class AppKernel extends Kernel
{
    public function registerBundles()
    {
        $bundles = array(
            ...
            new Netpositive\DiscriminatorMapBundle\NetpositiveDiscriminatorMapBundle(),

2, Using vendors

2.1 Add to the deps file

[NetpositiveDiscriminatorMapBundle]
    git=git://github.com/Netpositive/NetpositiveDiscriminatorMapBundle.git
    target=bundles/Netpositive/DiscriminatorMapBundle

2.2 Register the namespace in your autoload.php

// app/autoload.php
$loader->registerNamespaces(array(
    ...
    'Netpositive'      => __DIR__.'/../vendor/bundles',

2.3 Enable it at your kernel

// app/AppKernel.php
class AppKernel extends Kernel
{
    public function registerBundles()
    {
        $bundles = array(
            ...
            new Netpositive\DiscriminatorMapBundle\NetpositiveDiscriminatorMapBundle(),

Configuration

# app/config/config.yml
netpositive_discriminator_map:
    discriminator_map:
        content:
            entity: Netpositive\CmsBundle\Entity\Content
            children:
                course: University\CmsBundle\Entity\Content\Course
                phonebook_entry: University\CmsBundle\Entity\Content\PhonebookEntry
                ...

Parent class:

/**
 * Netpositive\CmsBundle\Entity\Content
 *
 * @ORM\Table(name="content")
 * @ORM\Entity()
 * @ORM\InheritanceType("JOINED")
 * @ORM\DiscriminatorColumn(name="content_type", type="string", length="20")
 * @ORM\DiscriminatorMap({"content" = "Content", "article" = "Article", ... })
 *
