以一对一关系插入数据属于To Sequelize

Question

I have two schema

• address
• employee

Each employee will have one address so, mine schema is as below

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;

Below is the Insertation Logic, It doesn't work, how can i perform association insertion

Item is an object from the array, where i have performed the 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

You will have to add two pieces of code.

In your first snippet, add

employee.hasOne(address);

In your second one, change

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));

to

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

Note: obj.address(address) becomes obj.setAddress(address).

Please let us know if this works!
