如何解决“关联的子对象不作为子数组嵌套到父对象中”

Question

我在做什么？

我试图同时获得所有testset对象及其所有方案。

父模型

'use strict';
module.exports = (sequelize, DataTypes) => {
  const Testset = sequelize.define('testset', {
    name: DataTypes.STRING
  }, {});
  Testset.associate = function(models) {
  };
  return Testset;
};

模型孩子

'use strict';
module.exports = (sequelize, DataTypes) => {
  const Scenario = sequelize.define('scenario', {
    name: DataTypes.STRING,
    mode: DataTypes.STRING,
    route: DataTypes.STRING,
    runQuantity: DataTypes.INTEGER,
    isTextOnly: DataTypes.BOOLEAN,
    testsetId: DataTypes.INTEGER
  }, {});
  Scenario.associate = function(models) {
  };
  return Scenario;
};

服务

const Promise = require('promise');
Scenario.belongsTo(Testset);
Testset.hasMany(Scenario);

    readAllTestsets () {
        return fromPromise(Testset.findAll({
            raw: true,
            include: [{
                model: Scenario,
                where: {
                    //testsetId: Testset.id
                }
            }]
        }));
    }

    readTestsetById (testsetId: number) {
        return fromPromise(Testset.findByPk(testsetId, {
            include: [{
                model: Scenario,
                where: {
                    testsetId: testsetId
                }
            }]
        }));
    }

我期望发生什么？

我希望在请求所有可用测试集的同时，将所有方案作为数组附加到引用的测试集（外键：testsetId）。它通过readTestsetById方法适用于单个测试集。我不明白为什么它会针对数据库中可用的场景数量复制testset对象，并将场景属性附加为case.attribute。

实际上发生了什么？

SELECT `testset`.`id`, `testset`.`name`, `testset`.`createdAt`, `testset`.`updatedAt`, `scenarios`.`id` AS `scenarios.id`, `scenarios`.`name` AS `scenarios.name`, `scenarios`.`mode` AS `scenarios.mode`, `scenarios`.`route` AS `scenarios.route`, `scenarios`.`runQuantity` AS `scenarios.runQuantity`, `scenarios`.`isTextOnly` AS `scenarios.isTextOnly`, `scenarios`.`testsetId` AS `scenarios.testsetId`, `scenarios`.`createdAt` AS `scenarios.createdAt`, `scenarios`.`updatedAt` AS `scenarios.updatedAt` 
FROM `testsets` AS `testset` 
INNER JOIN `scenarios` AS `scenarios` ON `testset`.`id` = `scenarios`.`testsetId`;

输出：
