.. _deprecation-94377:
|
|
|
|
===========================================================
|
|
Deprecation: #94377 - Extbase ObjectManager->getEmptyObject
|
|
===========================================================
|
|
|
|
See :issue:`94377`
|
|
|
|
Description
|
|
===========
|
|
|
|
Extbase has the odd behavior that
|
|
:php:`\TYPO3\CMS\Extbase\DomainObject\DomainObjectInterface` objects -
|
|
typically classes in :file:`Classes/Domain/Model` of Extbase enabled
|
|
extensions - don't call :php:`__construct` when the persistence layer
|
|
"thaws" a model from database - typically when an Extbase
|
|
:php:`Domain/Repository` uses a :php:`->findBy*` method.
|
|
|
|
As a side-effect of switching away from Extbase :php:`ObjectManager` towards
|
|
symfony based dependency injection, this behavior will change in TYPO3 v12:
|
|
Method :php:`__construct()` will be called in v12 when the :php:`DataMapper`
|
|
creates model instances from database rows.
|
|
|
|
|
|
Impact
|
|
======
|
|
|
|
There is no impact in TYPO3 v11 and no deprecation log entry is raised.
|
|
However, extension developers *should* prepare toward this change in v11
|
|
to avoid any impact of a breaking change in v12.
|
|
|
|
|
|
Affected Installations
|
|
======================
|
|
|
|
Extbase extensions having domain models that implement :php:`__construct()`
|
|
are affected. It is rather unlikely this has any impact on the behavior
|
|
of the extension, though.
|
|
|
|
Additionally, calls to API method
|
|
:php:`TYPO3\CMS\Extbase\Object\ObjectManager->getEmptyObject()` should be
|
|
avoided since it will vanish in v12. The vast majority of extensions will
|
|
not do this, though. The extension scanner will find candidates.
|
|
|
|
|
|
Migration
|
|
=========
|
|
|
|
No migration possible. Simply expect that :php:`__construct()` of a domain
|
|
model will be called in v12 when a domain repository :php:`findBy` method
|
|
directly or indirectly reconstitutes a model object from a database row.
