How to remove related models in Laravel?

Question

Laravel

Let's say there are Post and Comment models, a one-to-many relationship.
Is there a way to "out of the box" remove all related comments when deleting a post?
Tried

Post::with('comments')->where('id',  '=',  $id)->delete();

deletes only posts.

Answer 1

As answered above, You
can call it conveniently using model events.
In your model:

// ...

public function boot()
{
     Post::deleted(function ($post) {
          $post->comments()->delete();
     });
}
