Question

我试图设置环回，到目前为止，我已经创建了一个与mysql，模型的数据库连接，现在我正在使用api explorer来测试它，但我在任何调用时都会遇到这个错误：

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

以下是完整回复：

{
  "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. The PersistedModel has not been correctly attached to a DataSource!\n    at throwNotAttached (C:\\cmdb\\node_modules\\loopback\\lib\\persisted-model.js:62:11)\n    at Function.find (C:\\cmdb\\node_modules\\loopback\\lib\\persisted-model.js:210:5)\n    at SharedMethod.invoke (C:\\cmdb\\node_modules\\strong-remoting\\lib\\shared-method.js:252:25)\n    at HttpContext.invoke (C:\\cmdb\\node_modules\\strong-remoting\\lib\\http-context.js:384:12)\n    at phaseInvoke (C:\\cmdb\\node_modules\\strong-remoting\\lib\\remote-objects.js:645:9)\n    at runHandler (C:\\cmdb\\node_modules\\loopback-phase\\lib\\phase.js:135:5)\n    at iterate (C:\\cmdb\\node_modules\\async\\lib\\async.js:146:13)\n    at Object.async.eachSeries (C:\\cmdb\\node_modules\\async\\lib\\async.js:162:9)\n    at runHandlers (C:\\cmdb\\node_modules\\loopback-phase\\lib\\phase.js:144:13)\n    at iterate (C:\\cmdb\\node_modules\\async\\lib\\async.js:146:13)"
  }
}

这是我的model-config.json

Answer 1

您的EaAssets模型的数据源为null，因此内置的远程方法无法附加

（find，findbyid，create）方法尚未设置环回
