Doctrine Mappings for Value Objects and Enumerations

Provides a basic set of mapping information for the somnambulist/value-objects library for use with Doctrine. Mappings are available for Doctrine (.dcm.yml) and Symfony (.orm.yml). The mappings are symlinked from symfony to doctrine.

A Bootstrapper is included for automatically registering the value-object enumerations as Doctrine types.

Requirements

• PHP 7+
• Doctrine ORM 2.5+

Installation

Install using composer, or checkout / pull the files from github.com.

• composer require somnambulist/value-object-doctrine-mappings

Usage

Copy or link the mapping files to your project in the Doctrine configuration. These are needed per entity manager. It is highly recommended to extend the value-objects to your own and then copy and adapt the mappings as you need.

Remember: value-objects are part of your domain model and should be treated with care.

Note: enumerations are used in these mappings.

Register Enumeration Handlers

To register the enumeration handlers add the following to your applications bootstrap code (e.g.: AppBundle::boot or AppServiceProvider::register|boot):

Somnambulist\Doctrine\Bootstrapper::registerEnumerations();

This will pre-register the following enumerations:

• Geography\CountryCode
• Geography\Srid
• Measure\AreaUnit
• Measure\DistanceUnit
• Money\CurrencyCode

In addition extra helpers are registered to allow the Country and Currency value objects to be used as enumerations. These are stored using the CountryCode and CurrencyCode values and restored using the ::create() method.

Register Custom Types

Custom types are included for:

• datetime
• datetimetz
• date
• time
• json
• jsonb
• json_collection

The date types override the default Doctrine types and uses the VO DateTime that is an extended DateTimeImmutable object.

json, jsonb and json_collection are equivalent and allow JSON data to be converted to and from a Collection object instead of a plain array.

To register the types add the following to your application bootstrap:

Somnambulist\Doctrine\Bootstrapper::registerTypes();

Mapping Files

To use the types and enumerations, in your mapping files set the type appropriately:

To use the value-objects:

Or in XML format:

When using embeddables, be sure to have added the necessary mapping files.

Configuring Types for Symfony

Within a Symfony project, add a new mapping area to your orm configuration within the doctrine section:

Then either copy or symlink the appropriate config files from vendor config folder to your projects mapping config section. If you have different requirements for field type, copy and update as appropriate. It is recommended to copy and not link the mapping files to avoid issues with this library changing.
