SchemaError：没有为属性给出地图架构：播放列表

Question

我正在尝试创建 DynamoDB 架构和用户模型。但每当我调用我的 User 模型时，我的 api 总是会抛出这个错误：

SchemaError: No map schema given for attribute: playlist

。代码如下：

/models/v2/schema.js

const dynamoose = require('dynamoose');

const schemaOpt = { saveUnknown: true, timestamps: true };

const playlistSchema = new dynamoose.Schema({
    "description": String,
    "id": String,
    "name": String,
    "image": String
}, schemaOpt);

const userSchema = new dynamoose.Schema({
    "pk": {
        type: String,
        hashKey: true
    },
    "sk": {
        type: String,
        rangeKey: true
    },
    "playlist": {
        type: Object,
        schema: playlistSchema
    }
}, schemaOpt);

module.exports = userSchema;

/模型/v2/用户

'use strict';

const dynamoose = require('dynamoose');
const userSchema = require('./schema');

const UserModel = dynamoose.model("User", userSchema);


exports.User = UserModel;

使用示例

'use strict';
const rfr = require('rfr');
const { User } = rfr('/models/v2/user')

以上使用代码导致我的API抛出错误

No map schema given for attribute: playlist

Answer 1

saveUnknown

opt 将允许您存储具有 1 级未知属性的属性

playlist

const schemaOpt = { saveUnknown: ["playlist.*"], timestamps: true };

const userSchema = new dynamoose.Schema({
    "pk": {
        type: String,
        hashKey: true
    },
    "sk": {
        type: String,
        rangeKey: true
    },
    "playlist": Object
}, schemaOpt);
