javascript - sequelize.js 自定义验证器，检查唯一的用户名/密码

Question

假设我定义了以下自定义验证器函数:

isUnique: function () { // This works as expected
  throw new Error({error:[{message:'Email address already in use!'}]});
}

但是，当我尝试查询数据库时遇到问题:

isUnique: function (email) { // This doesn't work
  var User = seqeulize.import('/path/to/user/model');

  User.find({where:{email: email}})
    .success(function () { // This gets called
      throw new Error({error:[{message:'Email address already in use!'}]});  // But this isn't triggering a validation error.
    });
}

如何在自定义验证器中查询 ORM 并根据 ORM 的响应触发验证错误？

您可以像这样验证电子邮件是否已经存在:

email: {
  type: Sequelize.STRING,
  allowNull: false,
  validate: {
    isEmail:true
  },
  unique: {
      args: true,
      msg: 'Email address already in use!'
  }
}
