级联删除TYPO3内联记录不起作用

Question

I have a TYPO3 extension for some products wich uses inline records to add documentgroups to a product. Deleting the product should also delete the documentgroups (inline records).

The documentation says behaviour.enableCascadingDelete is set to true by default, but the documentgroups are not deleted. Setting this value in the TCA does not make a difference.

'documentgroups' => [
    'exclude' => 1,
    'label' => $ll . ".documentgroups",
    'config' => [
        'type' => 'inline',
        'allowed' => 'tx_product_domain_model_docgroup',
        'behaviour' => [
            'allowLanguageSynchronization' => true,
            'enableCascadingDelete' => true,
        ],
        'foreign_table' => 'tx_product_domain_model_docgroup',
        'MM'            => 'tx_product_mm',
        'MM_match_fields' => [
            'tablenames' => 'tx_product_domain_model_docgroup',
            'fieldname' => 'documentgroups',
            'table_local' => $tableName,
        ],
        'foreign_sortby' => 'sorting',
        'minitems' => 0,
        'maxitems' => 99,
    ]
],

Answer 1

enableCascadingDelete has no effect on MM related tables. In \\TYPO3\\CMS\\Core\\DataHandling\\DataHandler->deleteRecord_procBasedOnFieldType the inline type is checked and only if it's of type field ( foreign_field must be set in the TCA) or list ( MM and foreign_field must not be set in TCA) child entries will be deleted.
