如何从sequelizejs模型定义创建数据库表？

const Sequelize = require('sequelize');
const sequelize = new Sequelize('database', 'username', 'password', {
  host: 'localhost',
  dialect: 'mysql' // 或者其他支持的数据库类型
});

const User = sequelize.define('user', {
  // 定义模型字段
  firstName: {
    type: Sequelize.STRING,
    allowNull: false
  },
  lastName: {
    type: Sequelize.STRING,
    allowNull: false
  }
});

sequelize.sync({ force: true }).then(() => {
  console.log('表已创建');
});

const User = sequelize.define('user', {
  id: {
    type: Sequelize.INTEGER,
    primaryKey: true,
    autoIncrement: true
  },
  // 其他字段定义
});

const Post = sequelize.define('post', {
  // 其他字段定义
});

User.hasMany(Post);
Post.belongsTo(User);
