actually i've wrote like this, to be consistent with the title above which is Supplying the Choices with a Callback Function

--------------------------------------------

You can also directly provide a constant containing an array to the ``choices`` option in the annotation::

// src/AppBundle/Entity/Author.php
namespace AppBundle\Entity;

use Symfony\Component\Validator\Constraints as Assert;

class Author
{
const GENRES = ['action', 'comedy'];

/**
* @Assert\Choice(choices=Author::GENRES)
*/
protected $genre;
}

.. warning::

The constant in the option is used without quotes.
