Challenge: Implementing Has Many/Belongs To
Last updated
Last updated
The accompanying repo contains a Vite app that has been built out for you to implement a has many / belongs to relationship between classes.
The app allows users to maintain a list of Authors and Books by those authors.
In the provided repository, you will find a Vite project in the app/ directory. Inside, there is a src/ and src-solution/ folder. Currently, the index.html file links to the src-solution/.
See what the completed app does by doing the following:
Change directories into app
npm i
npm run dev
Play around with the app!
To set up your project, return to index.html and change the script such that it loads the src/main.js file instead of the solution file.
Your task is to complete the Author and Book classes in the src/ folder.
Before you begin, read through the code and understand the structure.
The main.js file is the entry point. It already is making use of the Author and Book classes, even though they are incomplete. Read through the code in this file and make sense of what the file expects of the Author and Book class.
The models folder has two files, Author and Book.js, each defining a class. Book is exclusively used by Author while Author is used exlusively within main.js.
The utils folder has a getId.js file with an id-generating function for the classes above.
The render-functions.js file has functions for rendering the front end components. It doesn't interact with the classes at all. It just receives data from main.js to render. You do not need to touch this file.
Once you've compelted the Author and Book classes, replace the classes in the models folder with classes of your own to demonstrate a new has many / belongs to relationship. You should also update the front-end code to utilize your new classes.
Examples of has many / belongs to classes include:
Doctor and Appointment
Playlist and Song
Class and Student
Team and Player
Have fun!
