如何在Nodejs中使用Sequelize查询深度嵌套的父属性

const { Sequelize, Model, DataTypes } = require('sequelize');

const sequelize = new Sequelize('database', 'username', 'password', {
  host: 'localhost',
  dialect: 'mysql',
});

class User extends Model {}
User.init({
  name: DataTypes.STRING,
}, { sequelize, modelName: 'user' });

class Order extends Model {}
Order.init({
  amount: DataTypes.INTEGER,
}, { sequelize, modelName: 'order' });

User.hasMany(Order);
Order.belongsTo(User);

Order.findAll({
  include: [{
    model: User,
    attributes: ['name'],
  }],
})
  .then((orders) => {
    orders.forEach((order) => {
      console.log(order.user.name);
    });
  })
  .catch((error) => {
    console.error(error);
  });
