Symfony best practice: Where to place these constants?

Question

I am wondering where should I place constants, for example. to display status in symfony. I am used to installing them in the controller, but this is not so, and I prefer the essence, but not quite.

What right?

This is not "what do you think?" - the question is, I really want to know best practices and evaluate explanations or related sources. Both work, for now.

the controller or

namespace my\bundle\Controller;

class MyController {
    const STATUS_NEW     = 1;
    const STATUs_PENDING = 2;
    // ...
}

Object ?

namespace my\bundle\Entity;

class MyEntity {
    const STATUS_NEW     = 1;
    const STATUs_PENDING = 2;
    // ...
}

Example in a branch:

{% set statusNew = constant('my\\bundle\\Controller\\MyController::STATUS_NEW')%} {# or \\Entity\\ #}
{% if data.status == statusNew %}
    Hi, I'm new.
{% endif %}

Thanks in advance!

    const STATUS_NEW     = 1;
    const STATUs_PENDING = 2;
    // ...

   // For each const status
   public function isNew(){
     return $this->status == self::STATUS_NEW;
   }
}

{% if data.isNew %}{# more contract form: if data.new  #}
