Doctrine entity form type onetomany relationship

Question

I have a user class that has a onetomany self-referencing relationship (ancestor and decendents). And I have an invoice class, which references two users based on the ancestor-decendents relationship. Meaning that, a user creates an invoice, so the form's "from" property will have the logged in user, while the form's "to" property should be a selection from the logged in user's decendets. This is the invoice's buildForm method

public function buildForm(FormBuilderInterface $builder, array $options)
{

    $builder
        ->add('createdDate')
        ->add('from')
        ->add('to', 'entity', array('class' => 'Disty\SystemBundle\Entity\User'))
    ;
}

To keep it short, I want to somehow only show options of decendent users. Right now it shows all users registered.

Answer 1

You should take a look at the query_builder parameter that should do the trick.

Answer 2

If you look at the documentation you can find query_builder option of the entity form type. So you just need to modify query builder to retrieve only users which belong to the current logged in user.
