sequelize 获取查询结果(result)后， 如何在 result 上添加一个字段 ？

Question

let result = await user.findOne({

    where: post

  })

const friends = await sequelize.query(

      `SElECT DISTINCT * FROM user WHERE id IN 

      (SELECT targetId FROM friends WHERE sourceId = "${result.id}")`

    )

// 下面这行代码，未成功    

result.list = friends[0]
