javascript - findByIdAndUpdate 不断被捕获在 .catch 中

Question

因此，当我执行 findByIdAndUpdate 时，它​​不会按预期执行我的 promise 并进入我的捕获。我使用 res.json(req.user.id) 和 res.json(profileFields) 向 postman 发送了回复。这是我使用时得到的响应 个人资料字段

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

我在这里不知所措，因为我的所有字段都按预期将值传递到 user 和 $set 中。我不明白为什么它会成为我的目标

 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,

      from: {

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

    }
  ],

        required: true
      },
      fieldofstudy: {

      to: {
        type: Date,
        required: true
      },
      current: {
        type: Boolean,
        default: false
      },
      description: {
        type: String
      }
    }
  ],
  social: {
    youtube: {
      type: String
    },
    twitter: {
      type: String
    },
    facebook: {
      type: String
    },
    linkedin: {
      type: String
    },
    instagram: {
      type: String
    }
  },
  date: {
    type: Date,
    default: Date.now
  }
});

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

Answer 1

findByIdAndUpdate 用于通过其 _id 值查找要更新的文档，但您需要通过其 user 字段查找文档，因此你应该使用findOneAndUpdate相反:

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

无需手动将 req.user.id 转换为 ObjectId，因为 Mongoose 会根据您的架构中定义 user 的方式为您执行此操作。
