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

[Steffen Wickham]

Hi Philipp,

many thanks for your help! I really appreciate it! :)
As far as I can tell, everything is looking good for now. But I can't
select what kind of question I add for this Quiz.

I'd devided the whole thing in two packages. The first package
(lg_quizbase) contains all base functionallity like the FE plugins and
base classes and the second package (lg_quizbasetypes) add the most
basic question types like multiple choice,  text input, sorting and so
on. Here are my snippets:

[TCA snippet of my "Question" model]:
=====================================================================================
$TCA['tx_lgquizbase_domain_model_question'] = array(
    //'ctrl' => $TCA['tx_lgquizbase_domain_model_question']['ctrl'],
    'ctrl' => array('type' => 'type'),
    ...
);


[TypoScript of lg_quizbasetypes]:
=====================================================================================
config.tx_extbase{
    persistence{
        classes{
            LinkGroup\LgQuizbase\Domain\Model\Question {
                subclasses {
                    Tx_LgQuizbasetypes_TextInputQuestion =
LinkGroup\LgQuizbasetypes\Domain\Model\TextInputQuestion
                    Tx_LgQuizbasetypes_MultipleChoiceQuestion =
LinkGroup\LgQuizbasetypes\Domain\Model\MultipleChoiceQuestion
                    Tx_LgQuizbasetypes_SortingQuestion =
LinkGroup\LgQuizbasetypes\Domain\Model\SortingQuestion
                  }
            }
            LinkGroup\LgQuizbasetypes\Domain\Model\TextInputQuestion {
                mapping {
                    tableName = tx_lgquizbase_domain_model_question
                    recordType = Tx_LgQuizbasetypes_TextInputQuestion
                }
            }
            LinkGroup\LgQuizbasetypes\Domain\Model\MultipleChoiceQuestion {
                mapping {
                    tableName = tx_lgquizbase_domain_model_question
                    recordType = Tx_LgQuizbasetypes_MultipleChoiceQuestion
                }
            }
            LinkGroup\LgQuizbasetypes\Domain\Model\SortingQuestion {
                mapping {
                    tableName = tx_lgquizbase_domain_model_question
                    recordType = Tx_LgQuizbasetypes_SortingQuestion
                }
            }
        }
    }
}


In the list view I can add a new quiz and be able to add Questions to
it. But there are only the fields of the base type available and no
select box for the question type :(
What can be wrong with it?

Best regards,
Steffen
