[TYPO3-dev] EXTBASE :: Domain model inheritance for entities

[Philipp]

Write question as a superclass and define it as superclass via typoscript. Now you can add 3 types to your TCA and set that types field as recordType via TA (extbase config for your question model). Each type is then connected to a model which just extends the question model.

Some more specific chunks:
[TCA]
$TCA['tx_extension_domain_model_question'] = array (
	'ctrl' => array (
		'type' => 'type',
	)
);

That type is a TCA select field which holds your options:
Type 1: multiple
Type 2: text
Type 3: assignment

[Typoscript:]
config.tx_extbase.persistence.classes {

	Vendor\Extension\Domain\Model\Question {
		subclasses {
			Vendor\Extension\Domain\Model\MultipleChoiceQuestion = Vendor\Extension\Domain\Model\MultipleChoiceQuestion
			Vendor\Extension\Domain\Model\TextInputQuestion = Vendor\Extension\Domain\Model\TextInputQuestion
			Vendor\Extension\Domain\Model\AssignmentQuestion = Vendor\Extension\Domain\Model\AssignmentQuestion
		}
	}
	Vendor\Extension\Domain\Model\MultipleChoiceQuestion {
		mapping {
			tableName = tx_extension_domain_model_question
			recordType = multiple
		}
	}
	Vendor\Extension\Domain\Model\TextInputQuestion {
		mapping {
			tableName = tx_extension_domain_model_question
			recordType = text
		}
	}
	Vendor\Extension\Domain\Model\AssignmentQuestion {
		mapping {
			tableName = tx_extension_domain_model_question
			recordType = assignment
		}
	}
}


Now you can request all types of questions via a QuestionRepository or only specifics via a MultipleChoiceQuestionRepository

Your entity property in quiz would be like
/**
 * @var \TYPO3\CMS\Extbase\Persistence\ObjectStorage<\Vendor\Extension\Domain\Model\Question>
* @lazy
* @cascade remove
*/
protected $questions;
