(Sonata) Impossible to create a OneToOne relation without having an Admin linked to it

Question

I would like to create my application around Sonata but I'm encountering some problems ...

I extended the BaseUser to create my own User and I did the same for the UserAdmin. I created an other entity on which the User has a relation OneToOne BUT I don't want this entity to be manageable by the user with an Admin linked to this entity.

The only way I want the user to fill those entities will be by the UserAdmin, I tried something like this :

protected function configureFormFields(FormMapper $formMapper){
    parent::configureFormFields($formMapper);
    $formMapper
        ->tab('Client details')
            ->with('Client Identity', array('class' => 'col-md-6'))
                ->add("test", EntityType::class, array(
                   "class" => "AppBundle:PersonDetails",
                   "property_path" => "details.test"
                ))
            ->end()
        ->end();
}

Here is my User class :

/**
 * @ORM\Entity
 * @ORM\Table(name="fos_user")
 */
class User extends BaseUser
{
    /**
     * @ORM\Id
     * @ORM\Column(type="integer")
     * @ORM\GeneratedValue(strategy="AUTO")
     */
    protected $id;

    /**
     * @ORM\OneToOne(targetEntity="PersonDetails")
     * @ORM\JoinColumn(name="details_id", referencedColumnName="id")
     */
    private $details;

    public function __construct()
    {
        parent::__construct();
        $this->details = new PersonDetails();
    }

    /**
     * @return PersonDetails
     */
    public function getDetails()
    {
        return $this->details;
    }

    /**
     * @param PersonDetails $details
     */
    public function setDetails($details)
    {
        $this->details = $details;
    }
}

The only thing I'm getting there is a select which wants me to pick an existing PersonDetails (I suppose).

How can I achieve this ? And, if it can be easily achieved, why doesn't it appeared in the documentation ? I think this case is not really uncommon ..

Thanks for your help

Sonata will try to parse the string passed to add("test"), so we can access our entity not driven by any Sonata administration by a simple add("details.test").

We do not need any additional configuration for the relation to work. Just don't forget Doctrine configuration for Cascade Persist and Deletion :

In the class User :

public class User extends BaseUser{
    /**
     * @ORM\Id
     * @ORM\Column(type="integer")
     * @ORM\GeneratedValue(strategy="AUTO")
     */
    protected $id;

    /**
     * @ORM\OneToOne(targetEntity="PersonDetails", cascade={"persist", "remove"})
     * @ORM\JoinColumn(name="details_id", referencedColumnName="id")
     */
    private $details;

    // The rest of the class
}

and in the UserAdmin class :

protected function configureFormFields(FormMapper $formMapper)
{
    parent::configureFormFields($formMapper);

    $formMapper
        ->tab('Client details')
            ->with('Client Identity', array('class' => 'col-md-6'))
                ->add("details.test")
            ->end()
        ->end();
}
