node.js - 我想更新用户个人资料

Question

我只想更新那些字段，我传递的其他数据的键应该保持不变，但在我的情况下，我传递的更改其他数据的键设置为 null

import userModel from '../../models/usermodel'
import {Request,Response} from 'express'
import jwt from 'jsonwebtoken'

const editprofile = (req:Request,res:Response)=>{

    let newData = new userModel(req.body)

    const userObj = {
        email: req.body.email || null,
        first_name: req.body.first_name || null,
        last_name: req.body.last_name || null,
        dob: req.body.dob || null,
        phone: req.body.phone || null,
        gender: req.body.gender || null,
        // profile_img: req.file.filename || null
    };

    userModel.findByIdAndUpdate({'_id':req.body._id}, { $set: userObj }, { upsert: true, new: true })

    .then(result=>{
        res.status(200).json({success:true,message:"Profile Updated",customer:result})
        console.log('result',result)
    })
    .catch(err=>{
        res.status(404).json({success:false,message:"Something went wrong",error_message:err})
    })
}
export default editprofile

您可以使用循环来填充给定字段:

  let newObj = {};
    Object.keys(req.body).forEach(function(prop) {
        newObj[prop] = req.body[prop];
    });

或者

使用 findOne() 来获取记录字段:

  let query = { $set: {} };
  for (let key in req.body) {
    if (customer[key] && customer[key] !== req.body[key])// if the field we have in req.body exists, we're gonna update it
      query.$set[key] = req.body[key];
  }
