node.js - Sequelize - 在验证模型关联时获得正确的路径

Question

我使用 Sequelize 作为我的项目的 ORM。我有这个结构:

const Event = sequelize.define('event', {
    // fields defined
});

const Question = sequelize.define('question', {
    description: {
        type: Sequelize.STRING,
        allowNull: false,
        defaultValue: '',
        validate: {
            notEmpty: { msg: 'Description should be set.' }
       },
    },
    // other fields defined
});

Event.hasMany(Question);
Question.belongsTo(Event);

然后我创建一个 Event 模型的实例，关联，如下所示:

const body = {
    questions: [
        { description: '' } // is obviously invalid
    ],
    // some other fields
}

const newEvent = await Event.create(body, {
    include: [ Question ]
});

如果我有 Event 实例本身的验证错误，它会返回 SequelizeValidationError ，我可以在其中看到每个 path 的 ValidationErrorItem 属性。但是，当我在子模型上出现验证错误时，此验证错误的 path 属性不清楚:

{
    "message": "Description should be set.",
    "type": "Validation error",
    "path": "description",
    "value": "",
    "origin": "FUNCTION",
    "instance": {
        "required": true,
        "id": null,
        "description": "",
        "event_id": 60,
        "updated_at": "2018-06-11T12:25:04.666Z",
        "created_at": "2018-06-11T12:25:04.666Z"
    },
    "validatorKey": "notEmpty",
    "validatorName": "notEmpty",
    "validatorArgs": [
        {
            "msg": "Description should be set."
        }
    ],
    "__raw": {
        "validatorName": "notEmpty",
        "validatorArgs": [
            {
                "msg": "Description should be set."
            }
        ]
    }

问题是，不清楚是什么导致了这个错误以及哪个 child 是无效的。当我使用 Mongoose 作为 ORM 时，如果我也这样做，那么 path 属性将等于 questions.0.description 之类的东西，这样就更清楚了，这样您就可以看到哪个 child 无效。

所以，我的问题是:有没有办法在验证子模型的同时设置 path 属性？

显然它还没有出现，我已经在 Sequelize repo 上提交了一个问题，这里是:https://github.com/sequelize/sequelize/issues/9524
