Sonata/AdminBundle: Selected Option - php

Question

I'm new in Symfony and Sonata/AdminBundle. I would like to know how to mark selected an option when the entity has a field from other entity. For example: I have two entities: Shop and City. The Shop entity has a field called id_city.
My problem is when I'm rendering the edit form Shop because always the first id_city in the option is selected.
This is the piece of code where I'm rendering the configuration form in AdminStores class:
protected function configureFormFields(FormMapper $formMapper)
{
$formMapper
->tab('Tiendas')
->with('Content', array('class' => 'col-md-9'))
->add('nombreTienda', 'text')
->add('cifTienda', 'text')
->add('direccionTienda', 'text')
->add('personaContacto', 'text', array('required' => false,'empty_data' => ''))
->add('cp', 'text', array('label' => 'Código Postal', 'required' => false, 'empty_data' => '00000'))
->add('urlTienda', 'text', array('required' => false, 'empty_data' => ''))
->add('emailTienda', 'text')
->add('telefonoTienda', 'text')
->add('login', 'text')
->add('pass', 'password', array('required' => false))
->add('idMunicipio', 'entity', array(
'class' => 'AppBundle:Municipios',
'choice_label' => 'municipio',
'query_builder' => function (EntityRepository $er) {
$lista = $er->createQueryBuilder('ss')
->orderBy('ss.municipio', 'ASC');
},
'data' => $this->subject->getIdMunicipio()
)) // end array idMunicipio y add()
->add('idProvincia', EntityType::class, array(
'class' => 'AppBundle:Provincias',
'label' => 'Provincia',
'choice_label' => 'provincia',
'choice_value' => 'getId',
'by_reference' => true,
))
->add('descripcionTienda', 'textarea')
->end()
->end()
->tab('Multimedia')
->with('Content', array('class' => 'col-md-3'))
->add('fotoTienda', 'file', array(
'label' => 'Imagenes (puedes subir hasta 6 imágenes)',
'attr' =>array('class' => 'form-control', 'multiple' => 'multiple', 'accept' => 'image/*'),
'data_class' => null,
'required' => false,
'empty_data' => 'noDisponible',
));
}
In this piece of code, I'm recovering all cities in AdminStores class:
->add('idMunicipio', 'entity', array(
'class' => 'AppBundle:Municipios',
'choice_label' => 'municipio',
'query_builder' => function (EntityRepository $er) {
$lista = $er->createQueryBuilder('ss')
->orderBy('ss.municipio', 'ASC');
},
'data' => $this->subject->getIdMunicipio()
)) // end array idMunicipio y add()
I would like to know, please, the logic for " if this->id_city == entity->id_city then, option is selected".
Thanks in advance
I edit this comment because I think that I solved it.
In my AdminController called ShopsAdmin I have created a method called getAllMunicipios which return an array with their name and id:
$allCities = array(
'Tokyo' => 1
'Madrid => 2
);
This is the method:
protected function getAllMunicipios()
{
$municipios = $this->getConfigurationPool()
->getContainer()
->get('doctrine')
->getRepository('AppBundle:Municipios')
->findBy([], ['municipio' => 'ASC']);
$todosmunicipios = array();
foreach ($municipios as $municipio) {
$todosmunicipios[(string)$municipio->getMunicipio()] = (int)$municipio->getId();
}
return $todosmunicipios;
}
Now my AdminStores::configureFormFields method like that this:
->add('idMunicipio', 'choice', array(
'choices' => $this->getAllMunicipios(),
'required' => false,
'by_reference' => false,
'data' => $this->subject->getIdMunicipio()
))
It is a good way to do it? I think that the method that return all, must be placed into the entity and not int the controller but I dont know how do it static

Answer 1

just call setCity(\AppBundle\Entity\City $city) in your Shop entity. and give the right city entity as the first and only parameter. Do this before you render the form
