如果我要在 api-server 应用程序的 loopbackjs 中定义一个名为 User 的模型，我该怎么办？

Question

我创建了一个 api-server loopbackjs 应用程序，我想定义一个名为 User 的模型，它具有 与内置的完全不同的属性一个。所以当我运行 slc loopback:model 时，它会抛出如下错误。

events.js:163
      throw er; // Unhandled 'error' event
      ^
ValidationError: The `ModelDefinition` instance is not valid. Details: `name` is not unique (value: "User").

如果我真的需要在我的应用程序中调用一个名为 User 的模型，我真的很感激任何人都可以阐明这个问题。

Answer 1

loopback 带有一些内置模型；-) User 就是其中之一。以小写字母（用户）命名您的模型。

您的用户模型最好继承回环的用户模型，因为您可能需要许多已实现的功能。
