Display Many-To-One fields in Symfony2 forms? - symfony

Question

I am having two entity files one as Activite.php and another as Mesurage.php.
Now i want to display an Activite form with 3 fields typeActivite, emplacement and mesurage. the mesurage will be a selection that will fetch data from mesurage table. here is the code that i wrote inside Activite.php to create a many_to_one field for mesurage_id
/**
* #ORM\Id
* #ORM\ManyToOne(targetEntity="GestionEnvironnementale\ISO14001Bundle\Entity\Mesurage")
*/
private $mesurage;
Below is my Form generation Code :
class ActiviteType extends AbstractType {
public function buildForm(FormBuilderInterface $builder, array $options) {
$builder
->add('typeActivite'),
->add('emplacement'),
->add('mesurage', 'entity', array('class' => 'ISO14001Bundle:Mesurage'));
}
}
here is my form code :
<div class="well">
<form method="post" {{ form_enctype(form) }}>
{{ form_widget(form) }}
<br/> <input type="submit" value="Envoyer" class="btn btn-primary" />
</form>
<script src="{{ asset('js/jquery-2.1.1.min.js') }}"></script>
<script type="text/javascript">
$(document).ready(function()
{
var $container3 = $('div#gestionenvironnementale_iso14001bundle_activitetype_activiteMesurage');
var $lienAjout3 = $('Ajouter un mesurage');
$container3.append($lienAjout3);
$lienAjout3.click(function(h) {
ajouterMesurage($container3);
h.preventDefault();
return false;
});
var index3 = $container3.find(':input').length;
if (index3 == 0) {
ajouterMesuragePolluant($container3);
} else {
$container3.children('div').each(function() {
ajouterLienSuppression3($(this));
});
}
function ajouterMesurage($container3) {
var $prototype3 = $($container3.attr('data-prototype').replace(/__name__label__/g, 'Mesurage n°' + (index3+1))
.replace(/__name__/g, index3));
ajouterLienSuppression3($prototype3);
$container3.append($prototype3);
index3++;
}
function ajouterLienSuppression3($prototype3) {
$lienSuppression3 = $('Supprimer');
$prototype3.append($lienSuppression3);
$lienSuppression3.click(function(h) {
$prototype3.remove();
h.preventDefault();
return false;
});
}
});
the code works very well but I dont want to display the list of Mesurage, I want to display the form of Mesurage to add a new !!

Answer 1

If you want to display a form even for mesurage, you have to take a look at embed form
So, basically, you have to create a FormType for mesurage (call it MesurageFormType) and modify your ActiviteType as follows
class ActiviteType extends AbstractType {
public function buildForm(FormBuilderInterface $builder, array $options) {
$builder
->add('typeActivite'),
->add('emplacement'),
->add('mesurage', 'collection', array(
'type' => new MesurageFormType(),
'allow_add' => true,));
}
}
This should be fine but if you want to render in a different way your form you should use prototype and jquery
