Question

我有两个架构

地址
雇员

每位员工都有一个地址，因此我的架构如下

employee.js

const address = conn.define('address', {
    street: Sequelize.TEXT,
    city: Sequelize.STRING,
    postalCode: Sequelize.STRING,
});

const employee = conn.define('employee', {
    empId: {
        type: Sequelize.INTEGER,
    },
    name: {
        type: Sequelize.STRING,
    },
    joinDateTime: {
        type: Sequelize.DATE,
    },
});

address.belongsTo(employee);

employee.sync();
address.sync();
module.exports = employee;

下面是插入逻辑，它不起作用，我如何执行关联插入

Item是数组中的一个对象，我执行了forEach

const obj = {
    empId: item.empId,
    name: item.name,
    joinDateTime: item.joinDateTime,
};
const address = {
    street: item.street,
    city: item.city,
    postalCode: item.postalCode,
};
Employee.build(obj).save().then((resp) => {
    /* here how can i perform the insertion in associated address schema
obj.address(address) won't work */
    obj.address(address).then(() => console.log('created')).catch(err => 
    console.log(err));
}).catch(err => console.log(err));

Answer 1

您必须添加两段代码。

在您的第一个代码段中，添加

employee.hasOne(address);

在你的第二个中，改变

Employee.build(obj).save().then((resp) => {
    /* here how can i perform the insertion in associated address schema
obj.address(address) won't work */
    obj.address(address).then(() => console.log('created')).catch(err => 
    console.log(err));
}).catch(err => console.log(err));

到

Employee.build(obj).save().then((employee) => {
    employee.setAddress(address).then(() => console.log('created')).catch(err => 
    console.log(err));
}).catch(err => console.log(err));

注意：obj.address（地址）变为obj.setAddress（地址）。

如果有效，请告诉我们！

以一对一的关系插入数据属于Sequelize
