Tell us what’s happening:
it is timing out
/** 1) Install & Set up mongoose */
let mongoose = require('mongoose');
mongoose.connect("mongodb+srv://Brian:<password>@cluster0-i4hoz.mongodb.net/test?retryWrites=true&w=majority", { useNewUrlParser: true, useUnifiedTopology: true });
// Add mongodb and mongoose to the project's package.json. Then require
// mongoose. Store your Mongo Atlas database URI in the private .env file
// as MONGO_URI. Connect to the database using the following syntax:
//
// mongoose.connect(<Your URI>, { useNewUrlParser: true, useUnifiedTopology: true });
/** # SCHEMAS and MODELS #
/* ====================== */
const Schema = mongoose.Schema;
const personSchema = new Schema({
name: { type: String, required: true },
age: Number,
favoriteFoods: [String]
});
/** 2) Create a 'Person' Model */
// First of all we need a **Schema**. Each schema maps to a MongoDB collection
// and defines the shape of the documents within that collection. Schemas are
// building block for Models. They can be nested to create complex models,
// but in this case we'll keep things simple. A model allows you to create
// instances of your objects, called **documents**.
// Create a person having this prototype :
// - Person Prototype -
// --------------------
// name : string [required]
// age : number
// favoriteFoods : array of strings (*)
// Use the mongoose basic *schema types*. If you want you can also add more
// fields, use simple validators like `required` or `unique`, and set
// `default` values. See the [mongoose docs](http://mongoosejs.com/docs/guide.html).
// <Your code here >
const Person = mongoose.model("Person", personSchema);
// **Note**: Glitch is a real server, and in real servers interactions with
// the db are placed in handler functions, to be called when some event happens
// (e.g. someone hits an endpoint on your API). We'll follow the same approach
// in these exercises. The `done()` function is a callback that tells us that
// we can proceed after completing an asynchronous operation such as inserting,
// searching, updating or deleting. It's following the Node convention and
// should be called as `done(null, data)` on success, or `done(err)` on error.
// **Warning** - When interacting with remote services, **errors may occur** !
// - Example -
// var someFunc = function(done) {
// ... do something (risky) ...
// if(error) return done(error);
// done(null, result);
// };
/** # [C]RUD part I - CREATE #
/* ========================== */
/** 3) Create and Save a Person */
// Create a `document` instance using the `Person` constructor you build before.
// Pass to the constructor an object having the fields `name`, `age`,
// and `favoriteFoods`. Their types must be conformant to the ones in
// the Person `Schema`. Then call the method `document.save()` on the returned
// document instance, passing to it a callback using the Node convention.
// This is a common pattern, all the **CRUD** methods take a callback
// function like this as the last argument.
// - Example -
// ...
var p = new Person;
p.name = "Brian ";
p.age = 18;
p.favoriteFoods = ["eggs", "pizza"];
var createAndSavePerson = function(done){
p.save(function(err, data){
if (err){
return done(err);
}
return done(null, data);
});
};
