NoMethodError を解決させたい

NoMethodError in Customers::OrdersController#create
undefined method `cart_items' for #Customer:0x00000000043c4f48 Did you mean? cart_ids
@cart_items = current_customer.cart_items
上記のエラーが発生しております。@cart_items = current_customer.cart_itemsの部分でエラーが発生していると思い、コントローラーを確認したのですが、何が間違っているのかが分かりません。Rails初心者です。よろしくお願いします。
