I'm a big begginer in Symfony, coming from Ruby on Rails world and trying to get same behaviours.
I have a simple application with 2 entities : Product and Category, with the relation Product belongs to Category and Category has many Products.
class Category {
[ ... ]
/**
* @ORM\OneToMany(targetEntity="Product", mappedBy="category", cascade={"all"})
*/
protected $products;
}
class Product {
[ ... ]
/**
* @ORM\ManyToOne(targetEntity="Category", inversedBy="products", cascade={"all"})
*/
protected $category;
}
What I'm trying to do is to delete every nested products when I'm deleting a Category.
My current action looks like
public function deleteAction($id, Request $request)
{
$repository = $this->getDoctrine()->getRepository('AppBundle:Category');
$category = $repository->find($id);
$em = $this->getDoctrine()->getManager();
$em->remove($category);
$em->flush();
return $this->redirect('/categories/');
}
A simple method could be remove all the products in the controller, but it's not very maintainable and not very object oriented. I'm looking about a practice to remove all the products of the deleted category directly in the model. A method, in RoR, is the callbacks (named after_destroy), automatically called when the object is destroyed. Is there any looking-like method in Symfony ?
