我有这个错误

Name 'Order' is not defined

在以下条款中：

            try:
                order = Order.objects.from_request(request)
                cart = OrderCart(order)
            except Order.DoesNotExist:
                pass

Order在同一个文件中完全定义并且是model.Model

更具体地说，这是我正在使用的文件： https : //bitbucket.org/chris1610/satchmo/src/a04c87a539f3/satchmo/apps/satchmo_store/shop/models.py，第242行出现异常

为什么会这样？

更新：

这是回溯：

也许我只是遗漏了一些东西，但您指的是 CartManager 在定义之前的 Order 类。直到第 642 行才定义订单。我不太了解 Django 的内部工作原理，但我会尝试将 Order 类移到 CartManager 上方，看看它是否能让你克服这个错误。

备查。

我想你忘了导入订单类
