Body
When an entity is saved in my app, I want to add its <code>slug</code> field to a lookup table. To make this as least intrusive as possible, I wrote up an event subscriber. According to <a href="https://stackoverflow.com/questions/10374155/doctrine-inserting-in-postpersist-event">this post</a>, I cannot <code>INSERT</code> on <code>postUpdate</code> events, so I tried <code>postFlush</code>: <pre><code>class SlugsSubscriber implements EventSubscriber { public function getSubscribedEvents() { return array('postFlush'); } public function postFlush(PostFlushEventArgs $args) { $em = $args->getEntityManager(); $needsFlush = false; error_log("postFlush"); foreach ($em->getUnitOfWork()->getScheduledEntityInsertions() as $entity) { // To prevent short-circuit $tmp = $this->registerSlugs($entity, $entityManager); if($tmp) $needsFlush = true; } foreach ($em->getUnitOfWork()->getScheduledEntityUpdates() as $entity) { // To prevent short-circuit $tmp = $this->registerSlugs($entity, $entityManager); if($tmp) $needsFlush = true; } if($needsFlush) { error_log("Flushing"); $em->flush(); } } protected function registerSlugs($entity, EntityManager $entityManager) { error_log("register slugs"); if($entity instanceof Product) { $this->registerProductSlugs($entity, $entityManager); return true; } elseif($entity instanceof Category) { $this->registerCategorySlugs($entity, $entityManager); return true; } return false; } } </code></pre> However, when I try to save an entity now, the method <code>registerSlugs</code> is never called, neither on an update nor a new insertions. Where did I go wrong?

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.
