How to extract the data of the desired locale?

Question

symfony

I managed to implement a record in the database, data in different languages.
Based on the following source.
Writing to the database is as follows

$food = new Category;
$food->setName('Кофе');
$food->addTranslation(new CategoryTranslation('en', 'title', 'Coffee'));
$food->addTranslation(new CategoryTranslation('cn', 'title', '咖啡'));

$food->addTranslation(new CategoryTranslation('en', 'description', 'Description in English'));
$food->addTranslation(new CategoryTranslation('cn', 'description', '英文说明'));

$manager->persist($food);
$manager->flush();

return $message->success("Категория добавлена!");

As a result, I got something


. I guess everything was exactly as it was intended.
Attention to the question, how to correctly get the data and fill in the Entity in accordance with the selected locale?
