将应用程序部署到heroku时，我遇到了一个奇怪的问题。
因此，有两种方法可以创建订单。首先，无论何时付款，都会自动创建订单。这完全是通过Rails完成的。其次，Orders索引视图包含一个显示所有订单的表，以及一个用于创建新订单的表单，该表使用Angular。实际上，它更像是使用Angular进行练习的实验。
所以，整个过程在开发中运行良好。所有订单（通过两种方法创建）都显示正常，以及相应的用户ID，产品ID和总数（订单将花费的金额）。
但是，当我部署应用程序时，我遇到了一个奇怪的错误。一切正常，但通过付款创建的订单总数不会显示。这意味着，对于所有订单，用户ID和产品ID都会显示，而对于使用Angular创建的订单，订单总数会显示出来。仅对于没有Angular创建的订单，订单总数不会出现。
非常感谢一些帮助!!
