如何在laravel 5.2中克隆具有所有关系的雄辩的对象

Question

I want to make a clone from existing eloquent model with all its relations without using loops on relations because i may extend relations in future. For now i have an order model:

$table->bigIncrements('id');
$table->unsignedBigInteger('customer_id');
$table->timestamps();

and order has many items:

$table->bigIncrements('id');
$table->unsignedBigInteger('order_id');
$table->unsignedInteger('quantity');

there is another relations 'sell_orders:

$table->bigIncrements('id');
$table->unsignedBigInteger('order_id');

but i know it should be more than these in future. How can i make a clone from an order and all its relations? I found this code:

$order = Order::find(1);
$clone = $order->replicate();
$clone->push();
$clone->save();

This make a new model without any relations.
