如何通过sequelize在mysql数据库上使用关联别名

npm install sequelize mysql2

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

const User = sequelize.define('User', {
  name: Sequelize.STRING
});

const Post = sequelize.define('Post', {
  title: Sequelize.STRING
});

User.hasMany(Post, { as: 'Posts', foreignKey: 'userId' });

User.findAll({
  include: [
    { model: Post, as: 'Posts' }
  ]
}).then(users => {
  console.log(users);
});
