【问题描述】：

我已经用谷歌搜索了很多，并查看了有关堆栈溢出的其他解决方案，但没有发现任何可以解决我的问题的方法。定义模型以使用 mysql 而不是磁盘时，出现以下错误

verbose: Registering model `users` in Waterline (ORM) with definition :: 
 { identity: 'users',
  tableName: 'users',
  connections: 
       [ { pool: true,
       connectionLimit: 10,
       waitForConnections: true,
       adapter: 'sails-mysql' } ],
  config: 
   { host: 'localhost',
     port: 3306,
     user: 'root',
     password: 'password',
     database: 'sailsapp' },
  attributes: { name: 'string', email: 'string', phone: 'string' },

我在其他地方读到，新版本的sails.js (0.9.16) 存在一个已知错误，必须为每个模型指定适配器和配置。正如您从错误日志中看到的那样，我已经这样做了，但是我的模型的代码如下

module.exports = {
    adapter: 'mysql',
    config: {
        host: 'localhost',
        port: 3306,
        user: 'root',
        password: 'password',
        database: 'sailsapp'
    },

    attributes: {
        name: 'string',
        email: 'string',
        phone: 'string'
    }
};

我仍然遇到同样的错误。这是我的应用程序的 package.json 文件

{
    "name": "sailsjs",
    "private": true,
    "version": "0.0.0",
    "description": "a Sails application",
    "dependencies": {
        "sails": "0.9.16",
        "grunt": "0.4.1",
        "sails-disk": "~0.9.0",
        "ejs": "0.8.4",
        "optimist": "0.3.4"
    },
    "scripts": {
        "start": "node app.js",
        "debug": "node debug app.js"
    },
    "main": "app.js",
    "repository": "",
    "author": "",
    "license": ""
}

还有我的sails-mysql 版本的package.json 文件

{
  "name": "sails-mysql",
  "version": "0.9.9",
  "description": "MySQL adapter for Sails.js",
  "main": "lib/adapter.js",
  "scripts": {
    "test": "make test"
  }, ...

对于如何解决这个问题有什么建议吗？

【问题讨论】：

  • 此处重复问题：stackoverflow.com/questions/22548976/…
  • 正如我的问题中所解释的，这个答案对我不起作用，我只是遇到了同样的问题。为了让它工作，我必须将适配器配置信息添加到我的模型中，例如/api/models/User.js：我已经这样做了，我已经在我的问题中记录了这一事实
  • 使用 v0.9.16 中的新应用程序，我无法复制它。收到套接字事件后，错误似乎发生在lift上；您是否打开了一个网页，可能会在 Sails 提升时尝试重新连接您的服务器并写入数据？
  • 我会在早上试着调查一下。我确实为 on socket connect 添加了一些逻辑，所以这可能会导致问题。我会让你知道我想出什么

【解决方案1】：

在 v0.10 中，可以在 models.js 上定义连接名称，该名称是在 connections.js

上配置的

models.js 

 connection: 'someMysqlServer'

connections.js

 someMysqlServer: {
    adapter : 'sails-mysql',
    host    : 'localhost',
    user    : '',
    password: '', 
    database: ''
  }

【讨论】：

    【解决方案2】：

    将默认 adapters.js 文件 mysql 适配器对象从 myLocalMySQLDatabase 更改为简单的 mysql 似乎可以修复它。不知道他们为什么要更改 mysql 适配器对象的名称，但我们现在可以开始了。
