Sails API 获取错误 (500) ER_BAD_FIELD_ERROR

Question

我是帆船初学者，我正在尝试使用帆船和 mysql 创建我的第一个 API。我尝试在我的 mysql 控制台中创建 table 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 服务器收到以下错误。我的查询没有该字段，不确定这些字段是否是标准字段并附加在查询中，也不确定如何将这些字段自动创建为 table 的一部分。

error: Sending 500 ("Server Error") response:

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

但我收到上述错误，下面是我的 table.

mysql> desc message
    -> ;
+-------+-------------+------+-----+---------+----------------+
| Field | Type        | Null | Key | Default | Extra          |
+-------+-------------+------+-----+---------+----------------+
| name  | varchar(20) | YES  |     | NULL    |                |
| id    | int(4)      | NO   | PRI | NULL    | auto_increment |
+-------+-------------+------+-----+---------+----------------+
2 rows in set (0.03 sec)

我在模型 message.js

中有以下代码

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

  }
};

Answer 1

您似乎在该连接上设置了 migrate: safe，这意味着 Sails 无法更改您创建的 MySQL table。这很好，除了 Sails 查询包括迁移器通常添加的 createdAt 和 updatedAt 字段。您可以手动将这些列添加到 table（使用 datetime 类型）或将以下内容添加到您的模型配置中：

autoCreatedAt: false,
autoUpdatedAt: false

有关这些字段的更多信息in the docs。

当 liftng 航行时，它会提示输入数字 1 表示安全 2 用于类似的实验..选择 2 它会起作用..对我有用..
