(find, findbyid, create) 方法尚未设置环回

Question

我正在尝试设置环回，到目前为止，我已经创建了一个到模型 mysql 的数据库连接，现在我正在使用 api 资源管理器对其进行测试，但我一直在获取任何调用都会出现此错误：

"The find method has not been setup loopback. The PersistedModel has not been correctly attached to a DataSource!

完整回复如下：

{
  "error": {
    "name": "Error",
    "status": 500,
    "message": "Cannot call EaAssets.find(). The find method has not been setup. The PersistedModel has not been correctly attached to a DataSource!",
    "stack": "Error: Cannot call EaAssets.find(). The find method has not been setup.

  }
}

这是我的模型-config.json

Answer 1

您的 EaAssets 模型具有 null 的数据源，因此未附加内置远程方法

(find, findbyid, create) 方法尚未设置环回

the (find, findbyid, create) method has not been setup loopback

loopbackjs

strongloop
