Symfony2 Sonata Admin show attribute only as a readyonly text

Question

I have some immutable attributes on my entity to administrate with sonata-admin bundle.

I want to show them in the edit-view of the entity, but don't want to provide any mechanism to change it (e.g. the value shall not be inside a input field)

I couldn't find anything but this:

$formMapper
    ->add('post', 'entity', 
        array(
            'label' => 'Some post', 
            'attr' => array(
                'readonly' => true,
                'disabled' => true
            ),
            'class' => 'Acme\DemoBundle\Entity\Post'
        )
    )
;

I tried it out with read_only, readonly, disabled etc. all the stuff. It looks ok, it's now inside a dropdown (since it is an entity) and I can not modify it.

But I even don't want that. I really need it as text (the current one).

Especially this is annoying if you use DoctrineExtensions with softdeletable, timestampable, since every "save" saves also the form-data.

Changing the type to 'text' instead of 'entity' replaces the dropdown with a input-field.. So, what's the best approach here?

$formMapper
    ->add('post', 'entity', 
        array(
            'label' => 'Some post',
            'read_only' => true,
            'disabled'  => true,
            'class' => 'Acme\DemoBundle\Entity\Post'
        )
    )
;
