我正在通过设计构建一个拥有一个“主用户”的应用程序。此主用户创建我们正在跟踪的员工和项目的记录。当用户想要“结账”时，他会向 twilio 电话号码发送一条文本，这将为该项目创建一个新的“交易”，要么签入要么签出。所以我有三个表——“员工”、“项目”和“交易”。计划是拦截这些传入的文本，解析它来自的电话号码，他们发短信的项目，以及他们给出的代码，即“CI 12345”将“签入项目 12345”等。无论如何，我我正在搭建这些东西，只是为了确保在我开始使用 API 来创建交易记录之前，我可以在 Web 应用程序中手动进行这些交易，但我很难将交易与项目（和/或用户）关联起来。交易需要有一个布尔“输入/输出”值、一个电话号码以将其与执行该操作的员工相匹配，然后是一个项目编号以将其与被跟踪的项目相关联。我不断收到错误消息，说我在尝试加载“交易显示视图”时没有为“交易”定义方法，可以这么说。我不确定这里发生了什么。这一切有点新，这只是我的第二个应用程序。然后是一个项目编号，将其与被跟踪的项目相关联。我不断收到错误消息，说我在尝试加载“交易显示视图”时没有为“交易”定义方法，可以这么说。我不确定这里发生了什么。这一切有点新，这只是我的第二个应用程序。然后是一个项目编号，将其与被跟踪的项目相关联。我不断收到错误消息，说我在尝试加载“交易显示视图”时没有为“交易”定义方法，可以这么说。我不确定这里发生了什么。这一切有点新，这只是我的第二个应用程序。
