迁移后如何向模式添加新属性？

Question

目前我正在做一个node.js项目，我在构建模式时发现了一个问题，通常，我使用http://docs.sequelizejs.com/manual/tutorial/migrations.html to define my schema, which is $ node_modules/.bin/sequelize model:generate --name User --attributes firstName:string,lastName:string,email:string , and after the $ node_modules/.bin/sequelize db:migrate, I can write these attributes into database. However, I am wondering how to add new attribute to schema after the migration, I searched and found this https://github.com/sequelize/cli/issues/133提供的命令行来讨论这个问题，但是之后我再次尝试了解决方案和运行 $ node_modules/.bin/sequelize db:migrate，它没有将新属性写入原始模式，我不明白问题出在哪里，下面是我的代码，我正在尝试添加两个属性'address'& 'height' 进入用户模式，你们能给我一些建议吗？谢谢！

'use strict';
module.exports = {
  up: (queryInterface, Sequelize) => {
    let migration = [];
    migrations.push(queryInterface.addColumn(
            'address',
            'height',
            {
                type: Sequelize.STRING,
              }
        ));

    return Promise.all(migrations);
    return queryInterface.createTable('Users', {
      id: {
        allowNull: false,
        autoIncrement: true,
        primaryKey: true,
        type: Sequelize.INTEGER,
      },
      firstName: {
        type: Sequelize.STRING,
      },
      lastName: {
        type: Sequelize.STRING,
      },
      email: {
        type: Sequelize.STRING,
      },
      createdAt: {
        allowNull: false,
        type: Sequelize.DATE,
      },
      updatedAt: {
        allowNull: false,
        type: Sequelize.DATE,
      },
    });
  },

  down: (queryInterface, Sequelize) => {
    return queryInterface.dropTable('Users');
  }
};

这个问题已经解决了，你可以用下面的link to solve that issue, also you can check the query part of sequelize to see the documents http://docs.sequelizejs.com/class/lib/query-interface.js~QueryInterface.html，真正的答案应该是

module.exports = {
  up: function (queryInterface, Sequelize) {
    return [
      queryInterface.addColumn(
        'users',
        'height',
        {
          type: Sequelize.STRING,
        }
      ),
      queryInterface.addColumn(
        'users',
        'address',
        {
          type: Sequelize.STRING,
        }
      )
    ];
  },

  down: function (queryInterface, Sequelize) {
    return [
      queryInterface.removeColumn('users', 'height'),
      queryInterface.removeColumn('users', 'address')
    ];
  }
};

然后你可以输入

sequelize migration:create --name add-height-and-address-to-user
sequelize db:migrate

将新属性迁移到您的模型中。
