Mongoose Modeling – Embedded & Referenced Documents

Introduction

Note: This can be a pair programming activity or done independently.

To practice using Mongoose, we will design a small data persisting application to keep track of airport data with different models: Airport, Terminal, Flight, and Passenger. You will have to write the models and then hard code data in your app.js file according to the requirements below. Since we're not worried about Express or views in this activity, log the results of your data persistence in the console when the file is executed - with node app.js - so we know what's being saved.

Exercise

Requirements

  • Create an Express application with four models: Airport, Terminal, Flight, and Passenger

  • Include Mongoose and create embedded and referenced models:

    • Airport
      • Name(String)
      • country(String)
      • terminals(Array of embedded Terminal Objects)
      • opened(Date)
    • Terminal
      • name(String)
      • flights(Array of referenced Flight Objects)
      • capacity(Number)
    • Flight
      • from(String)
      • to(String)
      • airline(String)
      • passengers(Array of referenced Passenger Objects)
    • Passenger
      • firstName(String)
      • lastName (String)
      • dob (Date)

  • Create the following data in app.js:

    • A flight from CDG France to JFK New-York, USA on American Airlines with no passengers. Assign this object to variable "flight1"
    • A second flight from Heathrow UK to JFK New-York, USA on British Airways with no passengers. Assign this object to variable "flight2"
    • An airport called JFK in the USA opened on a random date in 1990. Assign this object to variable "airport1"
    • A terminal called Terminal 1 that is pushed to airport1 with a capacity of 234324 and two flights: flight1 and flight2

  • Save and console.log all the objects and their children in the console - you should see all objects when node app.js is executed.

Starter code

No starter code for this app, create it from scratch !

Deliverable

The app's folder structure should look like this:

├── app.js
├── models
│   ├── airport.js
│   ├── flight.js
│   ├── passenger.js
│   └── terminal.js
├── node_modules
└── package.json

You should see all your objects when logged in the console when node app.js is executed.
