php - How to set up default value in symfony2 select box with data from database

Question

I have this code

->add('user', 'entity', array(
                            'class' => 'AcmeEntityUser',
                            'query_builder' => function(EntityRepository $er) use ($options)
     {                        return $er->createQueryBuilder('u')
                               ->orderBy('u.name', 'ASC');
                            },
            'data' => $option['id']
            ))

Its not working

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


    {
            $builder
              ->add('description')

              ->add('user', 'entity', array(
                'class' => 'AcmeEntityUser',
                'query_builder' => function(EntityRepository $er) use ($options) {
                    return $er->createQueryBuilder('u');

                },
              'preferred_choices' => array('2')
              ))
        ;
    }

Answer 1

You can use the one of the following:

1. Set a default value in the object

   $cl->setUser($this->getDoctrine()->getEntityManager()->getReference('Acme:User',2));
   

2. Use a preferred choices option in the form builder:

   'preferred_choices' => array('2')
   

3. Or set 'property_path' => false and use a 'data' => YourDefaultEnity
