Catalyst Doctrine Discriminator Map Bundle

Catalyst Discriminator Map Bundle

Symfony bundle that allows the specification of Doctrine discriminator maps in bundle configuration files instead of under the parent entity., _(*1)

This bundle removes the dependency of the parent entity on the children entities., _(*2)

Configuration

Minimum requirement is to have a dmap.yml file under the Resources/config directory of the bundle with the parent entity., _(*3)

Sample dmap.yml file:, _(*4)

entities:
    - parent: MyBundle\Entity\Person
      children:
        - id: person
          class: MyBundle\Entity\Person
        - id: employee
          class: MyBundle\Entity\Employee

You can have other dmap.yml files with the same parent entity in other bundles like so:, _(*5)

entities:
    - parent: MyBundle\Entity\Person
      children:
        - id: customer
          class: AnotherBundle\Entity\Customer

Discriminator Mapping Example

How discriminator mapping is normally done:

Entity:, _(*6)

<?php
namespace MyProject\Entity;

/**
 * @Entity
 * @InheritanceType("SINGLE_TABLE")
 * @DiscriminatorColumn(name="discr", type="string")
 * @DiscriminatorMap({"person" = "Person", "employee" = "Employee"})
 */
class Person
{
    // ...
}

/**
 * @Entity
 */
class Employee extends Person
{
    // ...
}

How to do it with this bundle:

Entity:, _(*7)

<?php
namespace MyProject\Entity;

/**
 * @Entity
 * @InheritanceType("SINGLE_TABLE")
 * @DiscriminatorColumn(name="discr", type="string")
 */
class Person
{
    // ...
}

/**
 * @Entity
 */
class Employee extends Person
{
    // ...
}

Configuration File (dmap.yml):, _(*8)

entities:
    - parent: MyProject\Entity\Person
      children:
        - id: person
          class: MyProject\Entity\Person
        - id: employee
          class: MyProject\Entity\Employee
