Laravel event when deleting by foreign key?

Question

Laravel

Let's say there are Category and Product models. They are connected one to many.
The provider has event Product::deleted().
But it only works if you delete the product.
How to call it if the product is automatically deleted when the category is deleted?

Answer 1

class Category extends Eloquent
{
    public function products()
    {
        return $this->has_many('Product');
    }
    protected static function boot() {
        parent::boot();
        static::deleting(function($Category) {
             $Category->products()->delete();
        });
    }
}

Thus, before deleting a category, we first delete all products, then delete the category.
