    Thank you, I have managed to create an order. Now the issue is when the order is created I need to destroy the cart but doing so caused the cart_item to be nil because 
    cart has many cart_item dependent: :destroy
    So I will not be able to display the total order price in the order index page as shown below
    <strong>Total price </strong> <%= order.cart_items.sum(&:total_price) %>

    But in the orders controller, I need to destroy the cart
    class OrdersController < ApplicationController
  
  def create
    @order = Order.new(order_params)
    current_cart.cart_items.each do |item|
      @order.cart_items << item 
    end

    @order.user = current_user 
    @order.save
    Cart.destroy(session[:cart_id])
    session.delete(:cart_id)
    redirect_to orders_path, notice: "Thank you for your order"
  end

  private
    def set_order
      @order = Order.find(params[:id])
    end
    def order_params
      params.require(:order).permit(:pay_method)
    end
end

    What is the right way to delete the cart?
