node.js - Mongoose save() 实际上并没有保存

Question

我正在尝试查找我的记录、更新并保存它。我可以看到数据已更新，并且仍然可以在 save() 回调中显示更新后的数据。但是，当我访问数据库时，它实际上未更新:

Skills.findOne({ skillsCat: req.body.skillsCat }, (err, gets)=> {
  if (err) {
      res.send(err)
      return
  }

  if (gets && gets.skillName.indexOf(req.body.skillName) !== -1) {
    // Here I update my data
    gets.percent[gets.skillName.indexOf(req.body.skillName)] = req.body.percent
    Console.log(gets);   // Here I can see the data is updated

    return gets.save((err, updated)=> {
      Console.log(updated);   // Here I can see the data is updated
      if (err) { return }
      res.json({
        message: 'Skill updated successfully',
        data: updated
      })
    })

  } else {
    return
  }
})

有没有人遇到过类似的问题并帮助我解决这个问题？谢谢。

尝试下面的代码:

gets.percent[gets.skillName.indexOf(req.body.skillName)] = req.body.percent
Console.log(gets);   // Here I can see the data is updated

//Notice that 'fieldname' is the name of actual field in database
 gets.markModified('fieldname');

return gets.save((err, updated)=> {
  Console.log(updated);   // Here I can see the data is updated
  if (err) { return }
  res.json({
    message: 'Skill updated successfully',
    data: updated
  })
})
