Question

这是我第一次将sails.js与mySQL数据库一起使用，我对这个错误感到很困惑。

我有一个控制器＆amp;模型叫做公司＆＃39;。它涉及表＆＃39;公司＆＃39;在mySQL数据库中。该表本身与两个名为＆＃39; module＆＃39;模块的表有一对多关联。和＆＃39;用户＆＃39; （每个用户/模块必须与一个公司ID连接）。我在MySQL数据库中设置了外键。

问题是..每次我从这个控制器打开任何页面/动作时，都会出现这个错误：

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

这是我的公司型号：

    module.exports = {
  attributes: {
      name:{
        type:"string",
        required:true,
        unique:true,
        minLength: 2
      },
      type:{
        type:"string",
        enum: ['hq','sub'],
        defaultsTo: 'hq'
      },     
      desc:{
        type:"text",
        required:true
      },
      logo: {
        type: 'string'
      },
      address: {
        type: 'text'
      },
      city: {
        type: 'string'
      },
      region: {
        type: 'string'
      },
      country: {
        type: 'string'
      },
      zipcode: {
        type: 'string'
      },
      phone_number: {
        type: 'string'
      },
      website: {
        type: 'string'
      }
  },
};

我尝试使用＆＃39; autoPK：false＆＃39;，＆＃39; schema：true＆＃39;，添加＆＃39; columnName / fieldName＆＃39;，但它们都没有工作。

错误是什么意思？我该如何解决？

非常感谢。

Oppening localhost：1337 / company / index是你的问题，不是任何mysql或其他orm问题！

这是一个路由配置探测器。当您打开此URL时，默认的sails行为是您尝试通过默认的REST api访问特定的公司记录。检查默认休息routes behavior。

为了在您的案例中更加明确，sails会解释您正在使用id＆＃34; index＆＃34;查询特定公司。这不是数字NaN因此您会收到此错误。

RESTful路线，路径始终为/：modelIdentity或 /：modelIdentity /：id。
