CartLine model should touch Cart parent timestamps

[adevade]

When adding a CartLine to the cart I think that the updated_at timestamp of the Cart should be automatically "touched". The same goes for other closely coupled relationships as well imo.

Or do you think that is up to the developer to implement?

https://laravel.com/docs/10.x/eloquent-relationships#touching-parent-timestamps

class CartLine extends BaseModel
{
+   protected $touches = ['cart'];

    public function cart()
    {
        return $this->belongsTo(Cart::class);
    }
}
