Create and Save a Record of a Model

Curriculum Help
1

I read the “Create Record” section in the second link I included but I am still confused about how to go about doing this. I understand I need to basically:

  1. Create a model of a person, using the schema from exercise 2
  2. Create a new person, including their attributes
  3. Save the new person you created
  4. Put your new person inside the createAndSavePerson function

But I just feel stuck on how to do it. I see the format in the example the problem gave and I also see the example in the second link, but I am still confused. Can someone help me?

require('dotenv').config();


let mongoose = require('mongoose');

const mySecret = process.env['MONGO_URI']

mongoose.connect(mySecret, { useNewUrlParser: true, useUnifiedTopology: true });

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

  • are you saying you are not sure where exactly “those implementations” should go into?
  • its supposed to be in “createAndSavePerson” and not outside
  • there is a typo of two semicolon

lets refer to instructions

Then, call the method document.save() on the returned document instance

  • as you have “Person” document at hand now you need to call “save” method on it, which is an “async” method, so its expected that you would handle it that way
  • look exercise “save” function call method and use it that way

is there something specific you need help with, please ask away, happy learning :slight_smile:

Thanks for the response! Gave it try but I am still doing something wrong

second attempt didn’t work either, this problem got me so confused, I don’t want to just look at the answer though

  • why are you using “createAndSavePerson” in this way, rather use “Person” schema into this given “handler function”
  • see there is another “handler function” with that same name, simply move your “schema and save” into that "handler function
  • once you moved you codes to that handler function, then make use of “done” when its a successful save action

see if that helps, happy learning :slight_smile:
