Extbase TypeConverter to fetch hidden records from persistence (Using this will *always* fetch hidden models of the specified type)

ext_localconf.php

<?php

\TYPO3\CMS\Extbase\Utility\ExtensionUtility::registerTypeConverter('MyVendor\\MyExtension\\Property\\TypeConverters\\MyPersistentObjectConverter');

PersistentObjectConverter.php

<?php
namespace MyVendor\MyExtension\Property\TypeConverters

use TYPO3\CMS\Extbase\Property\TypeConverter\PersistentObjectConverter

class MyPersistentObjectConverter extends PersistentObjectConverter {

	/**
	 * @var string
	 */
	protected $targetType = 'MyVendor\\MyExtension\\Domain\\Model\\MyModel';

	/**
	 * @var int
	 */
	protected $priority = 2;
  
	/**
	 * Fetch an object from persistence layer.
	 *
	 * @param mixed $identity
	 * @param string $targetType
	 * @throws \TYPO3\CMS\Extbase\Property\Exception\TargetNotFoundException
	 * @throws \TYPO3\CMS\Extbase\Property\Exception\InvalidSourceException
	 * @return object
	 */
	protected function fetchObjectFromPersistence($identity, $targetType) {
		if (ctype_digit((string)$identity)) {
			$query = $this->persistenceManager->createQueryForType($targetType);
			$query->getQuerySettings()->setIgnoreEnableFields(TRUE);
			$constraints = $query->equals('uid', $identity);
			$object = $query->matching($constraints)->execute()->getFirst();
		} else {
			throw new \TYPO3\CMS\Extbase\Property\Exception\InvalidSourceException('The identity property "' . $identity . '" is no UID.', 1297931020);
		}

		if ($object === NULL) {
			throw new \TYPO3\CMS\Extbase\Property\Exception\TargetNotFoundException('Object with identity "' . print_r($identity, TRUE) . '" not found.', 1297933823);
		}

		return $object;
	}
  
}

Thanks a lot! Very helpful.

Is there any way to add this only for specific routes (e.g. controller & actions)?

Actually yes! :-) An approach I found quite useful if you have scenarios where the type converter shall depend on the action or argument and not on source and target type. That can be done by not registering the typeConverter but instead to configure property mapper in your specific ation to use that specific type converter for a specific argument. You can do so in the initalize(Foo)Action methods.

Example:
$this->arguments->getArgument('myargument')->getPropertyMappingConfiguration()->setTypeConverter($this->objectManager->get(MyTypeConverter::class));
