Show value form choices field (formtype) in list view twig (Symfony2)

I have a issue with choices and formtype. Short description of my problem :

I have formtype with field that has choices 

->add('fieldName2', 'choice', array(
        'label' => 'Some label',
        'choices' => array(
            0 => 'Option 1',
            1 => 'Option 2',
            ...,
            n => 'Option n'
        ),
    ))

In database that field is int (must be a number). Now comes the problem : I want to list all the records for that table. Result is like :

fieldName1|fieldName2
----------|----------
somevalue | 0
somevalue | 1
somevalue | 2

but I wont to look like this:

fieldName1|fieldName2
----------|----------
somevalue | Option 1
somevalue | Option 2
somevalue | Option 3

How to combine formtype field choices and actual values in template. Do I have to create custom twig function for that or there is a built in solution?

Assuming $data contains your fields from a database in a controller, create the "choices" array:

$choices = array();
foreach ($data as $elem)
{
  $choices[$elem] = "Option {$elem}";
}

Then, create your form and pass your choices array in constructor.

$form = $this->createForm(new YourFormType($choices), new YourFormData());

In your form, add a constructor:

private $choices;

// (...)

public function __construct(array $choices)
{
  $this->choices = $choices;
}

Finally, create your field with your previously prepared array of choices.

(...)
->add('fieldName2', 'choice', array(
        'label' => 'Some label',
        'choices' => $this->choices,
))

Note: replace the property name "choices" by a less confusing name; will be easier to read if you have several choices that looks like this.
