dcsdynamicdiscriminatormapbundle's Introduction

DynamicDiscriminatorMapBundle

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
