Symfony 2 Embedded Forms
I am embedding a form type into another form type like so
$builder->add('parent', new \Company\Bundle\Form\UserObjects\AParentType);
However when I try and bind the request to the form
if($request->getMethod() == 'POST') {
$form->bindRequest($request);
}
I get the error
Catchable Fatal Error: Argument 1 passed to Company\Bundle\Entity\UserObjects\User::setParent() must be an instance of Company\Bundle\Entity\UserObjects\AParent, array given, called in /Volumes/Media/Symfony/vendor/symfony/src/Symfony/Component/Form/Util/PropertyPath.php on line 346 and defined in /Volumes/Media/Symfony/src/Company/Bundle/Entity/UserObjects/User.php line 771
It seems like the form is passing the "AParent" object as an array instead of as an entity. Any ideas?

Answer
You haven't set the data class in your AParentType form. You do that like this:
public function getDefaultOptions(array $options)
{
return array(
'data_class' => 'Project\MyBundle\Entity\AParent',
);
}
For later versions of Symfony, you'll need to use this instead:
use Symfony\Component\OptionsResolver\OptionsResolverInterface;
//...
public function setDefaultOptions(OptionsResolverInterface $resolver)
{
$resolver->setDefaults(array(
'data_class' => 'Project\MyBundle\Entity\AParent',
));
}
Replace this:
->add('parent', new \Company\Bundle\Form\UserObjects\AParentType);
With this:
->add('parent', new AParentType());
because you've already included the namespace.
And if it's one-to-one, which it is, in your form template, you do:
{{ form_row(form.parent.zipCode) }}
Hopefully that should work. Your entity definitions look fine :-)
