Migrate post to joomla

[joomlablr]

If we migrate post and articles to joomla, in admin parts we don`t see any articles, while in DB (phpmyadmin) we see all of this. We need add this article to table #__workflow_associations - near 993 rows in Wordpress.php in plugins

           //old parts with article
           $article->language = '*';
           $article->note = "";

           //new part code for  workflow
           $workflow = new stdClass();
           $workflow->item_id = $articleid;
           $workflow->stage_id = 1;
           $workflow->extension = "com_content.article"; 

           $jdb = Factory::getDbo()->insertObject($tablePrefix . 'content', $article);

//new code for write worklow tables
           $jdb = Factory::getDbo()->insertObject($tablePrefix . 'workflow_associations', $workflow);

And i think we need create the same for asset table

    ```
        $asset = Table::getInstance('Asset', 'JTable', array('dbo' => $db));
        $assets = new stdClass();
        $assets->parent_id = $parentAssetId; // ID parent element
        $assets->name = "com_content.article".$articleid;
        $assets->title = $row['post_title']; // this must be article title
        $assets->rules = '{}';

if (!$asset->store()) {
throw new Exception($asset->getError());
}
$jdb = Factory::getDbo()->insertObject($tablePrefix . 'assets', $assets);

And next one - this is error with migrates users. Now we need come back and do it again - than  we migrate user. And in articles created_by  user is wrong. Can we something do with it?
