Symfony2在表单类型中使用doctrine

I would like to create an optgroup in symfony2 like this:

$category_choices = array(
    array('Category 1' => array(
        '1' => 'Option 1...',
        '2' => 'Option 2...',
        '3' => 'Option 3...'
    )),
    array('Category 2' => array(
        '4' => 'Option 4...',
        '5' => 'Option 5...'
    ))
);

$builder->add('category_list', 'choice', array(
    'label' => 'Category',
    'choices' => $category_choices
));

But I want to get the category choices from the database and I need to execute some actions on them and add them to an array. How can I do this in the same form type? (use doctrine in form type)
