Question

我正在使用Sequelize作为我项目的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);

然后我创建了一个Event模型的实例，带有关联，就像那样：

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

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

如果我对Event实例本身有验证错误，则返回SequelizeValidationError，我可以在其中看到每个path的{{1}}属性。但是，当我在子模型上遇到验证错误时，此验证错误的ValidationErrorItem属性不明确：

path

问题是，目前还不清楚导致此错误的原因以及哪个孩子无效。当我使用Mongoose作为ORM时，如果我这样做，{ "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." } ] }属性将等同于path，这样就更清楚了，这样你就可以看到孩子无效。

所以，我的问题是：有没有办法在验证子模型时设置questions.0.description属性？

显然它还没有出现，我在Sequelize回购中提出了一个问题，这里是：https://github.com/sequelize/sequelize/issues/9524
