如何在树枝i Symfony中访问自定义对象？

Question

Inside a controller I check if user has access to a video if not AccessDeniedHttpException is thrown.

//check if user has access to this asset or not
if(!$this->get("asset.access_manager")->hasAccess($asset)){
   throw new AccessDeniedHttpException($this->get("translator")->trans("exception.asset.access.unauthorized"));
}

how can I pass $asset object which contains all information about the video to the Twig which is used by exception to show message? By accessing $asset object I can print information about video on Exception page.

Thank you

if you want to check the permission (role?) I think the better way is:

{% if app.user.username is defined and is_granted('ROLE_ADMIN') %}
     //some awesome code here
{% else %}
     //without permission here
{% endif %}

First check if the user exist and later check his role.
