Question

我正在使用StrongLoop和Loopback来创建API。我已将内置的User模型扩展为我自己的名为people的模型。我不希望User模型在默认情况下要求提供类似的电子邮件，因此我关注了this work around，现在当我使用默认的User模型创建用户时，电子邮件就是'需要。但是当我使用我的people模型时，仍然需要它。我在这里缺少什么？

此外，当我将people模型连接到MySQL数据库时出现奇怪错误。如果我有默认的内存连接器，即使用db数据源，我可以创建用户就好了，但当我将它连接到MySQL数据库时，我得到：

{
  "error": {
    "name": "ValidationError",
    "status": 422,
    "message": "The `people` instance is not valid. Details: `username` is     invalid (value: \"username123\"); `email` is invalid (value: \"testing@email.com\").",
"statusCode": 422,
"details": {
  "context": "people",
  "codes": {
    "username": [
      "uniqueness.Error: ER_BAD_FIELD_ERROR: Unknown column 'realm' in 'field list'"
    ],
    "email": [
      "uniqueness.Error: ER_BAD_FIELD_ERROR: Unknown column 'realm' in 'field list'"
    ]
  },
  "messages": {
    "username": [
      "is invalid"
    ],
    "email": [
      "is invalid"
    ]
  }
},
"stack": "ValidationError: The `people` instance is not valid.

  }
}

以下是该模型的样子：

"name": "people",
  "base": "User",
  "idInjection": true,
  "options": {
    "validateUpsert": true
  },
  "properties": {
    "id": {
      "type": "number",
      "required": true
    },
    "username": {
      "type": "string",
      "required": true
   },
    "email": {
      "type": "string"
    },
    "password": {
      "type": "string",
      "required": true
    },
    "created": {
      "type": "string"
    }
  },
  "validations": [],
  "relations": {},
  "acls": [],
  "methods": {}
}
