Sails.js Sails API获取错误（500）ER\u错误\u字段\u错误

我是sails的初学者，我正在尝试使用sails和mysql创建我的第一个API。我尝试在mysql控制台中创建表，并对configuration.js文件进行配置，并尝试在chrome浏览器中从POSTMAN访问API。我从sails服务器得到以下错误。我的查询没有字段，也不确定这些字段是否是标准字段，是否会追加到查询中，也不确定如何自动创建这些字段作为表的一部分

Details:  Error: ER_BAD_FIELD_ERROR: Unknown column 'message.createdAt' in 'fiel
d list'

我在model message.js中有以下代码

module.exports = {
connection: 'someMysqlServer',
  attributes: {
        name: { type: 'string',
                 required: true}

  }
};

看起来您可能在该连接上设置了

migrate:safe

，这意味着Sails无法更改您创建的MySQL表。这很好，只是Sails查询包含迁移器通常添加的

createdAt

和

updatedAt

字段。您可以手动（使用

datetime

类型）将这些列添加到表中，也可以将以下内容添加到模型配置中：

autoCreatedAt: false,
autoUpdatedAt: false

---

有关这些字段的更多信息。

当liftng航行时，它会提示输入数字1，以便安全2进行类似的实验。.选择2它会起作用。.对我有效。

非常感谢您的回答，我解决了问题，将这些列添加到表中。是的，你是对的，我在扬帆的时候就有过这样的经历。

autoCreatedAt: false,
autoUpdatedAt: false
