Sequelize设置相关的值

我有两个模型， 员工和办公室 。 每个员工属于一个办公室，办公室有很多员工。

我很难找出如何使用Sequelize更新员工办公室。

Employee模型如下：

let Employee = sequelize.define("Employee", { id: { field: 'id', type: DataTypes.INTEGER, primaryKey: true, allowNull: false, autoIncrement: false }, name: { field: 'name', type: DataTypes.STRING(255), allowNull: false } }, { freezeTableName: true, timestamps: false, deletedAt: false }) Employee.associate = models => { Employee.belongsTo(models.Office, { foreignKey: 'id' }) } 

Office模型如下：

 let Office = sequelize.define("Office", { id: { field: 'id', type: DataTypes.INTEGER, primaryKey: true, autoIncrement: true }, name: { field: 'name', type: DataTypes.STRING(255), allowNull: false } }, { freezeTableName: true, tableName: 'Lkup_Office', timestamps: false, deletedAt: false }) Office.associate = models => { Office.hasMany( models.Employee, { foreignKey: 'id' }) } 

在数据库中，我有以下员工：

 { "id": "2", "name" : "John", "office": { "id": 2, "name" : "Seattle" } } 

…以及下列办事处：

 [ { "id": 1, "name" : "Chicago" }, { "id": 2, "name" : "Seattle" } ] 

我想把Employee（1）办公室的ID从2 （ 'Seattle' ）改为1 （ 'Chicago' ）; 问题是用下面的查询

 // PUT /2/office/1 router.put('/:employeeId/office/:officeId', (req, res) => { models.Employee.findOne({ where:{id:req.params.employeeId}, include:[{model:models.Office}] }).then( employee => { models.Office.findOne({ where:{id:req.params.officeId}, include:[{model:models.Employee}] }).then( office => { employee.setOffice( office ).then( result => { res.send( result ) }) }) }) }) 

…我的员工办公室没有更新：

 { "id": "2", "name" : "John" "office": { "id": 2 "name" : "Seattle" } } 

事实上，它根本就没有做任何事情：没有错误，数据库没有改变。 我有一个怀疑，有一些我不正确的做法，但Sequelize没有抛出任何错误。

Answer 1

 router.put('/:employeeId/office/:officeId', (req, res) => { /*In this first part, I just separated the two queries into two separate variables*/ let employeeInfo = models.Employee.findOne({ where: { id: req.params.employeeId }, include: [{ model: models.Office }] }); let officeInfo = models.Office.findOne({ where: { id: req.params.officeId }, include: [{ model: models.Employee }] }); /*In this next part, we have to use Promise.all, which comes with bluebird, which is already a part of Sequelize.js. How this next part is executed will depend on how you have your Sequelize.js code structured in your application. This may require some trial and error*/ models.sequelize.Promise.all([employeeInfo, officeInfo]).then(([Employee, Office])=> { return Employee.setOffice(Office); }).catch(err => { console.log(err); }); });
