Hi guys! I just wanted to you to know that I fixed that i just had to add to my backend controller those lines:
protected function getDetailQuery($id) {
$builder = parent::getDetailQuery($id);
$builder->leftJoin('shop_comments.shop','shop');
$builder->addSelect(['shop']);
return $builder;
}
protected function getListQuery() {
$builder = parent::getListQuery();
$builder->leftJoin('shop_comments.shop','shop');
$builder->addSelect([('shop')]);
return $builder;
}
I just missed them in documentation ! :)
