sails-mysql无数据库选择

Question

我在googled上搜索了相当多的内容，并查看了堆栈溢出的其他解决方案，但没有发现任何解决方案可以解决我的问题。当定义一个使用mysql而不是磁盘的模型时，我会得到以下错误

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' },
  globalId: 'users',

我在其他地方读到，新版本的sails.js (0.9.16)有一个已知的错误，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所示

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

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

我还是会犯同样的错误。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": ""
}

以及我的sails版本的package.json文件-mysql

{
  "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？

Answer 1

将默认的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。

Answer 2

在v0.10中，可以在connections.js上配置的models.js上定义连接名称

models.js

 connection: 'someMysqlServer'

connections.js

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