Using Symfony2 entity field type one should specify property option: $builder->add('customers', 'entity', array( 'multiple' => true, 'class' => 'AcmeHelloBundle:Customer', 'property' => 'first', )); But sometimes this is not sufficient: think about two customers with the same name, so display the email (unique) would be mandatory. Another possibility is to implement __toString() into the model: class Customer { public $first, $last, $email; public function __toString() { return sprintf('%s %s (%s)', $this->first, $this->last, $this->email); } } The disadvances of the latter is that you are

I check some validation in my controller. And I want to add error to specific element of my form on failure.

My form looks like this: public function buildForm(FormBuilderInterface $builder, array $options) { $factory = $builder->getFormFactory(); $builder->add('name'); $builder->add('description'); $builder->add('manufacturers', null, array( 'required' => false )); $builder->add('departments', 'collection', array( 'type' => new Department )); } I have a class validator on the entity the form represents which calls: if (!$valid) { $this->context->addViolationAtSubPath('departments', $constraint->message); } Which will only add a 'global' error to the form, not an error at the sub path. I assume this

I am making a Symfony2 application which needs to have a multiple image upload option. I have made the single file upload using the cookbook entry: How to handle File Uploads with Doctrine which works fine. I have implemented the lifecyclecallbacks for uploading and removing.
