Sails.js中的模型验证失败

Question

我在Sails.js中测试了以下Employee.js模型,我发现了一些我觉得难以理解的东西.

当发布用于创建新Employee的表单时,我在Employee.js模型的第一个定义中遇到以下错误,但Employee.js的第二个定义有效.那么Employee.js的两个定义之间的区别是什么？

错误:

Error (E_VALIDATION) :: 3 attributes are invalid

Invalid attributes sent to Employee:
 • name
   • `undefined` should be a string (instead of "null", which is a object)
   • "required" validation rule failed for input: null
 • email
   • `undefined` should be a email (instead of "null", which is a object)

   • "required" validation rule failed for input: null
 • password
   • `undefined` should be a string (instead of "null", which is a object)
   • "required" validation rule failed for input: null

定义1:Employee.js

module.exports = {
  attributes: {

    name: {
      type: 'STRING',
    },

    email: {
      type: 'STRING',
      email: true,
    },

    password: {
      type: 'STRING',
    },

    toJSON: function() {
      var obj = this.toObject();

      return {
        name: obj.name,
        email: obj.email,
        password: obj.password
      }
    }

  }
};

定义2:Employee.js

module.exports = {
  attributes: {

    name: 'STRING',
    email: 'STRING',
    password: 'STRING',

    toJSON: function() {
      var obj = this.toObject();

      return {
        name: obj.name,
        email: obj.email,
        password: obj.password
      }
    }

  }
};

创建新员工的表单如下:

<form action="/signupemployee" method="POST">
  <table>
    <tr><td>Name</td><td><input type=”text” name=”name”></td></tr>
    <tr><td>Password</td><td><input type=”password” name=”password”></td></tr>
    <tr><td>Email</td><td><input type=”email” name=”email”></td></tr>
    <tr><td></td><td><input type="submit"></td>
  </table>
</form>

Answer 1

应该只存在一处差异。在您的第二个模型中，电子邮件属性不需要包含有效电子邮件格式的字符串。据我所知，定义如下：

name: {
    type: "STRING"
}

和

name: "STRING"

目的是等效的，因此这可能是 Waterline 中的一个错误。

尽管这个问题是不久前提出的，但仍然值得提出一个问题以确保它得到解决。
