How to configure 'entities' for a 'reusable bundle' in Symfony 4.x?

Question

I'm on symfony 4.x, I created a reusable bundle for an easyadmin add-on. I create an entity that is well known but when submitting data, I have a method _prePersist for HasLifecycleCallbacks that is not detected.

/**
 * @ORM\HasLifecycleCallbacks()
 * @ORM\Table
 * @ORM\Entity
 */
class Post
{}

/**
 * @ORM\PrePersist
 */
public function _prePersist()
{
  dump($this);die;
}

You will need to update your Bundle's configuration to register both the folder where you keep your entities and probably the lifecycle events as well. When placing them in src/Entity this is not necessary, because the DoctrineBundle already provides default configuration for that. This is why in your config/packages/doctrine.yaml you have the following:

doctrine:
    orm:
        mappings:
            App:
                is_bundle: false
                type: annotation
                dir: '%kernel.project_dir%/src/Entity'
                prefix: 'App\Entity'
                alias: App

You should track how the DoctrineBundle reads & processes this configuration from the Configuration.php and then how the Service Container is configured from these config values by looking at DoctrineExtension.php . You can probably omit the Configuration file, but your MyBundleExtension needs to update the Doctrine-services with your entity classes from inside the bundle.

Alternatively you can look at Recipes and instead of keeping the Entity in your bundle copy it into the src/ directory whenever your bundle is installed. Due to how recipes work, your bundle will need to be open source for this and you will have to provide a contrib-recipe for this bundle .

edit: Another option could be to provide a full skeleton for your basic setup, so that you don't need to worry about bundles and independent configuration and instead just provide a basic starter application with a default setup you deem useful.
