Body
<p>Here is my solution. It's not that elegant as I was hoping to get, but anyway at least it works. So, in my solution we first check if the emails collection is dirty (meaning that some emails were added and/or deleted). If it's not dirty we still need to check if any changes to the existing emails were made. I was hoping to use some existing API for that, but it seems there are none of them for this case. So, I decided to check my data manually for changes. Code example follows.</p> <pre><code>/** * * @Template() */ public function editAction($id, Request $request) { $repository = $this->getDoctrine()->getRepository('AcmeBundle:Person'); $person = $repository->find($id); if (!$person) { throw $this->createNotFoundException('No person found for id '.$id); } if ($request->isMethod('POST')) { $form->bind($request); if ($form->isValid()) { $em = $this->getDoctrine()->getEntityManager(); // isDirty() will be true if emails were added or deleted if ($person->getEmails()->isDirty()) { $person->setUpdated(new \DateTime(date('Y-m-d H:i:s'))); } else { $uow = $em->getUnitOfWork(); // as no one suggested a working solution, I just decided // to check entity by entity, field by field // if anything is changed, we'll mark $person as updated foreach($person->getEmails() as $item) { $orig = $uow->getOriginalEntityData($item); if ($item->getEmail() != $orig['email']) { $person->setUpdated(new \DateTime(date('Y-m-d H:i:s'))); break; } } } $em->flush(); } } return array('form' => $form->createView(), 'person' => $person); } </code></pre> <p>If anyone has any idea how to avoid one by one entity check, I would greatly appreciate if you share such a solution.</p>

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.
