MongoDB and Mongoose - Create Many Records with model.create()

Backend Development

Hello fellow campers,

I would like to ask for your help with this challenge, I feel that my code is fine, I did everything according to the documentation, but nevertheless it does not pass the test, this is my code…

require('dotenv').config();
/*Metodo para llamar la Variable de entorno*/
var mongoose = require('mongoose');
mongoose.connect(process.env.MONGO_URI);

/*let validator = require('validator')*/
/*Mongoose Schema*/
let personSchema = new mongoose.Schema({
  name: {
    type: String,
    required: true,
    unique: true
  },
  age: {
    type: Number,
    required: false
  },
  favoriteFoods: {
    type: [String], 
    required: true
  }/*,
  email:{
    type: String,
    required: true,
    unique: true,
    lowercase: true,
    validate: (value) => {
      return validator.isEmail(value) /*Función que valida que sea un formato correo hay que crear la variable al inicio 'validator'
    }
  }*/
});
let Person = mongoose.model('Person', personSchema);
/*Nuevo registro del Schema*/
var createAndSavePerson = (done) => {
  let personTest = new Person({
    name: 'Person Test',
    age: 25,
    favoriteFoods: ['Hamburger', 'Hot Dog', 'Ice cream']/*,
    email: 'persontest@mail.com'*/
  });
  personTest.save(function(err, data) {
    if (err) return console.error(err);
    done(null, data)
  });
};
/*Crear varios registros*/
  /* Primero se crea una variable con una matriz de objetos, segun el Schema*/
let arrayOfPeople = [
{name: "Frank Rocha", age: 74, favoriteFoods: ["Del Taco"]/*, email: "email1@mail.com"*/},
{name: "Sol Zolano", age: 76, favoriteFoods: ["roast chicken"]/*, email: "email2@mail.com"*/},
{name: "Robert Deniro", age: 78, favoriteFoods: ["wine"]/*, email: "email3@mail.com"*/}
];
/* Mediante esta función se hace el llamado del array-string creado anteriormente */
var createManyPeople = (arrayOfPeople, done) => {
  Person.create(arrayOfPeople, (err, people) => {
    if (err) return console.error(err);
    done(null, people);
  });
};

And this is the response from the console…

}

If anyone has any idea what might be going on, I’d be very grateful.

I think you should give the past challenges a check. When connecting to the database using Mongoose, mongoose.connect(process.env.MONGO_URI), you should pass a second argument with the following object: { useNewUrlParser: true, useUnifiedTopology: true }.

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

Thanks for your valuable contribution friend, I had not noticed that missing item, but additionally that error was appearing because in mongoose atlas, a collection had already been created with the name that I was registering, so I had to delete it from Atlas and return to pass the test and there if I pass,

Thank you for supporting those of us who are learning…

No problem
I’m also a learner too. So good luck with your future projects and freeCodeCamp challenges :smiley:
