MongoDb and Mongoose - Create a model

Backend Development

require('dotenv').config();
const mongoose = require('mongoose');

mongoose.connect(process.env.MONGO_URI, { useNewUrlParser: true, useUnifiedTopology: true });

const Schema = mongoose.Schema;
const personSchema = new Schema({
  name: {
    type: String,
    required: true
  },
  age: Number,
  favortieFoods: [String]
});

const Person = mongoose.model('Person', personSchema);


const createAndSavePerson = (done) => {
  done(null /*, data*/);
};

const createManyPeople = (arrayOfPeople, done) => {
  done(null /*, data*/);
};

const findPeopleByName = (personName, done) => {
  done(null /*, data*/);
};

const findOneByFood = (food, done) => {
  done(null /*, data*/);
};

const findPersonById = (personId, done) => {
  done(null /*, data*/);
};

const findEditThenSave = (personId, done) => {
  const foodToAdd = "hamburger";

  done(null /*, data*/);
};

const findAndUpdate = (personName, done) => {
  const ageToSet = 20;

  done(null /*, data*/);
};

const removeById = (personId, done) => {
  done(null /*, data*/);
};

const removeManyPeople = (done) => {
  const nameToRemove = "Mary";

  done(null /*, data*/);
};

const queryChain = (done) => {
  const foodToSearch = "burrito";

  done(null /*, data*/);
};

/** **Well Done !!**

//----- **DO NOT EDIT BELOW THIS LINE** ----------------------------------

exports.PersonModel = Person;
exports.createAndSavePerson = createAndSavePerson;
exports.findPeopleByName = findPeopleByName;
exports.findOneByFood = findOneByFood;
exports.findPersonById = findPersonById;
exports.findEditThenSave = findEditThenSave;
exports.findAndUpdate = findAndUpdate;
exports.createManyPeople = createManyPeople;

exports.removeManyPeople = removeManyPeople;
exports.queryChain = queryChain;

  1. Here is all my code, with this code ‘npm start’ and then I just copy and paste the URL of localhost, but challenge is not passed. What is wrong with this code? or anything I have to check?

  2. A message in terminal:
    (node:42528) [DEP0170] DeprecationWarning: The Url mongodb://~~~~~~~~~is invalid.Future versions of Node.js will throw an error.
    (Use node --trace-deprecation ... to show where the warning was created)

  3. A message in challenge:
    x: Creating an instance from a mongoose schema should succeed

please help me~

I couldn’t get the code to pass either, so I took help of chatgpt.
I figured it was my .env file.

My initial mongo_uri: (default MongoDB format URI)

mongodb+srv://<db_username>:<db_password>@cluster0.6ohpp.mongodb.net/?retryWrites=true&w=majority&appName=Cluster0

Corrected:

MONGO_URI=mongodb://yourUsername:yourPassword@localhost:27017/yourDatabase

This is all that I changed.
maybe the error is in .env for you too?

I even destructured the Schema variable:

const { Schema } = mongoose;

is equivalent to

const Schema = mongoose.Schema;

TYPO.
