在扩展安装TYPO3期间向表添加行

我尝试在安装自己的扩展程序时向表tx_gridelements_backend_layout添加一些数据行。为此,我使用文件" ext_tables_static + adt.sql"在我的扩展目录中。

但这只有在我删除表并在插入数据之前再次创建它时才有效。但是,那些可能已经存在的所有数据都将丢失。多数民众赞成绝对不是我想要的。我想在现有数据之外添加一些行。

我怎样才能实现这一目标?

另一个问题是,如果某人清除了表,他们如何意识到他们必须从sys_registry表中删除我的扩展并再次安装它,那么所有行都会再次添加?

我认为有更好的方式做这样的事情,或者?

因此灵魂是安装后信号扩展管理器正在发出的。为此,在我的ext_localconf.php中,我添加了:

if (TYPO3_MODE === 'BE') {
    $class = 'TYPO3\\CMS\\Extbase\\SignalSlot\\Dispatcher';
    $dispatcher = \TYPO3\CMS\Core\Utility\GeneralUtility::makeInstance($class);
    $dispatcher->connect(
    'TYPO3\\CMS\\Extensionmanager\\Service\\ExtensionManagementService',
        'hasInstalledExtensions',
        'FalkRoeder\\GridelementsFlex\\Setup\\Setup',
        'addBackendLayouts'
    );
}

和我的班级FalkRoeder / gridelements_flex / Classes / Setup / Setup.php:

class Setup
{

    protected $layouts = [
       1 => [
           'title'  => 'Flexbox 50 50',
           'config'  => 'backend_layout {\r\n    colCount = 4\r\n    rowCount = 1\r\n    rows {\r\n        1 {\r\n            columns {\r\n                1 {\r\n                    name = links außen\r\n                    colPos = 1\r\n                }\r\n                2 {\r\n                    name = links innen\r\n                    colPos = 2\r\n                }\r\n                3 {\r\n                    name = rechts innen\r\n                    colPos = 3\r\n                }\r\n                4 {\r\n                    name = rechts außen\r\n                    colPos = 4\r\n                }\r\n            }\r\n        }\r\n    }\r\n}\r\n',
           'pi_flexform_ds_file'  => 'typo3conf/ext/gridelements_flex/Configuration/Flexforms/two_column_flex.xml'
       ]
    ];

    public function addBackendLayouts( $extname = null )
    {
        if( $extname !== 'gridelements_flex' ) {
           return;
        }

        foreach ($this->layouts as $layout) {

            list($row) = $GLOBALS['TYPO3_DB']->exec_SELECTgetRows('COUNT(*) AS t', 'tx_gridelements_backend_layout', "title = '" . $layout['title'] . "'");
            $count = (int)$row['t'];

            if($count == 0) {
                $GLOBALS['TYPO3_DB']->exec_INSERTquery(
                    'tx_gridelements_backend_layout',
                    $layout
                );
            }
        }

    }
}
