DynamicDiscriminatorMapBundle simplifies the use of Doctrine Single Table and Class Table Inheritance mapping strategy in Symfony2

With this bundle you can adds dynamically all classes of a hierarchy to the options of DiscriminatorMap using a config file. This way you can apply the methodology of 'decoupling'

Installation

Step 1: Download DynamicDiscriminatorMapBundle using composer

Add DynamicDiscriminatorMapBundle in your composer.json:

{ "require": { "damianociarla/dynamic-discriminator-map-bundle": "dev-master" } } 

Step 2: Enable the bundle

Enable the bundle in the kernel:

<?php // app/AppKernel.php public function registerBundles() { $bundles = array( // ... new DCS\DynamicDiscriminatorMapBundle\DCSDynamicDiscriminatorMapBundle(), ); } 

Configuration

Parent class

This is an example of a parent class

<?php namespace Acme\PersonBundle\Entity; /** * @ORM\Entity * @ORM\Table(name="person") * @ORM\InheritanceType("SINGLE_TABLE") * @ORM\DiscriminatorColumn(name="type", type="string") * @ORM\DiscriminatorMap({"person" = "Person"}) */ class Person { // ... } 

Children classes

This is an example of two children classes

<?php namespace Acme\StudentBundle\Entity; use Acme\PersonBundle\Entity\Person; /** * @ORM\Entity */ class Student extends Person { // ... } <?php namespace Acme\TeacherBundle\Entity; use Acme\PersonBundle\Entity\Person; /** * @ORM\Entity */ class Teacher extends Person { // ... } 

Configuration file

# app/config/config.yml dcs_dynamic_discriminator_map: mapping: person: entity: Acme\PersonBundle\Entity\Person map: student: Acme\StudentBundle\Entity\Student teacher: Acme\TeacherBundle\Entity\Teacher
