[TYPO3-mvc] How do I set up sys_language_uid in controller?

[Jakub Zembala]

Hello Dmitry,
if You want set sys_language_uid to "-1" for all new portfolio, maybe good  solution for You will be set this value as default in SQL? 
Btw. as i learned You should create new object like this :
$newPortfolio = $this->objectManager->create("TYPO3\\Gcmodels\\Domain\Model\\Portfolio");
