Doctrine lifecycle callbacks not working with EasyAdminBundle - php

Question

I am using Symfony 4 with EasyAdminBundle to create a simple administrative interface. I'm having a few problems trying to automatically set the value for createdAt and updatedAt columns. When creating/updating an entity within EasyAdmin, the configured Doctrine lifecycle callbacks are not called. For example, here's a simple entity that is managed with EasyAdmin, note the lifecycle callback hooks:
<?php
namespace App\Entity;
/**
* #ORM\Entity(repositoryClass="App\Repository\ProductRepository")
* #ORM\HasLifecycleCallbacks
*/
class Product
{
/**
* #ORM\Id()
* #ORM\GeneratedValue()
* #ORM\Column(type="integer")
*/
private $id;
// Additional column configuration removed for brevity
/**
* #ORM\Column(type="datetime")
*/
private $createdAt;
/**
* #ORM\Column(type="datetime", nullable=true)
*/
private $updatedAt;
// Additional getters/setters removed for brevity
public function getCreatedAt(): ?\DateTimeInterface
{
return $this->createdAt;
}
public function setCreatedAt(?\DateTimeInterface $createdAt): self
{
$this->createdAt = $createdAt;
return $this;
}
public function getUpdatedAt(): ?\DateTimeInterface
{
return $this->updatedAt;
}
public function setUpdatedAt(?\DateTimeInterface $updatedAt): self
{
$this->updatedAt = $updatedAt;
return $this;
}
/**
* #ORM\PrePersist
*/
public function onPrePersist(): void
{
$this->createdAt = new \DateTime();
}
/**
* #ORM\PreUpdate
*/
public function onPreUpdate(): void
{
$this->updatedAt = new \DateTime();
}
}
When I create a new product within EasyAdmin, onPrePersist() is not called, and when I edit an existing product with EasyAdmin, onPreUpdate() is not called.
If I create a new product the "traditional" way, the lifecycle callbacks work exactly as expected. For example:
<?php
$product = new Product();
$product->setTitle('Test Product');
$product->setDescription('Test description');
// Doctrine lifecycle callbacks work as expected
$this->getDoctrine()->getManager()->persist($product);
Is EasyAdminBundle bypassing Doctrine lifecycle callbacks? If so, why? How do I utilize Doctrine lifecycle callbacks within Doctrine entities managed by EasyAdminBundle?
I understand there is documentation to do something similar with an AdminController:
https://symfony.com/doc/master/bundles/EasyAdminBundle/book/complex-dynamic-backends.html#update-some-properties-for-all-entities
But again, why do I need to do this when we already have Doctrine lifecycle callbacks. My other problem with using an AdminController and extending various methods, persistEntity() within AdminController is never called either.
What am I missing?
Any help would be greatly appreciated! Cheers!
