Hoe de namen van de id's in mangoest te krijgen?

U moet als volgt invullen:(het is ook een goed idee om gebruikerswachtwoorden uit te sluiten)

 Question.find({})
    .populate("user", "-password")
    .populate("answered.user", "-password");

Ik heb ook een paar codesuggesties:

Over het algemeen gebruiken we namen met een hoofdletter en enkelvoud voor modellen, zoals Gebruiker.

gebruiker.js

const mongoose = require("mongoose");

const UserSchema = new mongoose.Schema({
  name: {
    type: String,
    required: true
  },
  email: {
    type: String,
    required: true,
    unique: true
  },
  password: {
    type: String,
    required: true
  },
  date: {
    type: Date,
    default: Date.now
  }
});

const User = mongoose.model("User", UserSchema);

module.exports = User;

vraag.js

const mongoose = require("mongoose");

const QuestionSchema = new mongoose.Schema({
  user: {
    type: mongoose.Schema.Types.ObjectId,
    ref: "User"
  },
  question: {
    type: String
  },
  name: {
    type: String
  },
  answered: [
    {
      user: {
        type: mongoose.Schema.Types.ObjectId,
        ref: "User"
      }
    }
  ]
});

const Question = mongoose.model("Question", QuestionSchema);

module.exports = Question;

En u kunt de volgende zoekopdracht gebruiken om gebruikers in te vullen:

const Question = require("../models/question");

router.get("/question", async (req, res) => {
  const questions = await Question.find({})
    .populate("user", "-password")
    .populate("answered.user", "-password");

  res.send(questions);
});

Hier is voorbeelduitvoer:

        "_id": "5dc12a6aa875cd0ca8b871eb",

        },
