Body
<p>I have a Customer entity that only has a unique Email field to it. I am trying to edit a customer's email and the validation works fine. However I have this in my controller:</p> <pre><code>public function updateAction(Request $request, $id) { $em = $this->getDoctrine()->getManager(); $entity = $em->getRepository('AcmeDemoBundle:Customer')->find($id); if (!$entity) { throw $this->createNotFoundException('Unable to find Customer entity.'); } $editForm = $this->createForm(new CustomerType(), $entity); $editForm->bind($request); if ($editForm->isValid()) { $em->persist($entity); $em->flush(); return $this->redirect($this->generateUrl('ticket_result')); } var_dump($editForm->getErrors()); return $this->render('AcmeDemoBundle:Customer:edit.html.twig', array( 'entity' => $entity, 'edit_form' => $editForm->createView(), )); } </code></pre> <p>The var_dump returns an empty array but the validator sets a unique error and the <code>$editForm->isValid()</code> returns false. Is there a way to check for that specific error in the controller during validation, also can you explain why it returns an empty error array? Basically, I would like to provide the "merge" option if that error comes up.</p> <p><b>EDIT</b>: here is the formtype:</p> <pre><code>namespace Acme\DemoBundle\Form; use Symfony\Component\Form\AbstractType; use Symfony\Component\Form\FormBuilderInterface; use Symfony\Component\OptionsResolver\OptionsResolverInterface; class CustomerType extends AbstractType { public function buildForm(FormBuilderInterface $builder, array $options) { $builder ->add('email', 'email', array('required'=>true)) ; } public function setDefaultOptions(OptionsResolverInterface $resolver) { $resolver->setDefaults(array( 'data_class' => 'Acme\DemoBundle\Entity\Customer', 'cascade_validation' => true, )); } public function getName() { return 'acme_demobundle_customertype'; } } </code></pre> <p>And the twig template:</p> <pre><code>{% extends 'AcmeDemoBundle::layout.html.twig' %} {% block body -%} <h1>Customer edit</h1> <form action="{{ path('customer_update', { 'id': entity.id }) }}" method="post" {{ form_enctype(edit_form) }}> <input type="hidden" name="_method" value="PUT" /> {{ form_widget(edit_form) }} <p> <button type="submit">Edit</button> </p> </form> {% endblock %} </code></pre> <p>Here is my validation:</p> <pre><code>Acme\DemoBundle\Entity\Customer: constraints: - Symfony\Bridge\Doctrine\Validator\Constraints\UniqueEntity: fields: email message: "A customer under that email address already exists" properties: email: - Email: ~ </code></pre>

Guidance

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
