Question

因此，当我执行findByIdAndUpdate时，它没有按预期执行诺言，而是陷入困境。我使用res.json(req.user.id)和res.json(profileFields)向邮递员发送了回复。这是我使用时得到的回应 profileFields

{
    "user": "5b3134a0e2543b06d130a5d7",
    "handle": "wadeaston1",
    "status": "Developer",
    "skills": [
        "HTML",
        " CSS",
        " Javascipt"
    ],
    "social": {}
}

我不知所措，因为我所有的字段都按预期方式将值传递到user和$ set中。我不明白为什么它会吸引我

 Profile.findByIdAndUpdate(
      { user: req.user.id },
      { $set: profileFields },
      { new: true }
    )
      .then(profile => res.json(profile))
      .catch(err => {
        res.json("Timeout");
        console.log("HI");
      });

这是我的个人资料架构

const mongoose = require("mongoose");
const Schema = mongoose.Schema;

//Create Scheme
const ProfileSchema = new Schema({
  user: {
    //this will associate user by their ID
    type: Schema.Types.ObjectId,
    ref: "users"
  },
  handle: {
    type: String,
    required: true,
    max: 40
  },
  company: {
    type: String
  },
  website: {
    type: String

  location: {

    required: true

      from: {

        required: true
      },
      to: {
        type: Date,
        required: true
      },
      current: {
        type: Boolean,
        default: false

  date: {

});

module.exports = Profile = mongoose.model("profile", ProfileSchema);

Answer 1

根据您给出的错误，您似乎需要将req.user.id从string转到ObjectId：

Profile.findByIdAndUpdate(
  { user: new mongoose.Types.ObjectId(req.user.id) },
  { $set: profileFields },
  { new: true }
).then( /* rest of code */

这假设您进行了const mongoose = require('mongoose')或类似的操作。

Answer 2

findByIdAndUpdate用于通过_id值查找要更新的文档，但是您需要通过其user字段来查找文档，因此您应该使用findOneAndUpdate代替：

Profile.findOneAndUpdate(
      { user: req.user.id },
      { $set: profileFields },
      { new: true }
    )
    .then(...

无需手动将req.user.id强制转换为ObjectId，因为Mongoose会根据您在架构中定义user的方式为您完成此操作。

findByIdAndUpdate一直被.catch捕获
