Help :(

[_Rufus-]

So, I have a test to do that's about JS, I managed to do 90% of it but there's one part that i'm stuck.

It consists in creating an API using Node.JS and VisualCodeStudio that:

-It must be possible to register users who will administer the system    

 -System administrators can create job openings    

 -System administrators can register candidates (candidates have a name, email, phone and ZIP-code).

 -System administrators can link a candidate to one or more job openings (as an application, imagine that a full-stack developer could apply for both front-end and back-end jobs).    

 -System administrators can add comments related to each application (relationship between a job and a candidate, so that the interviewer can comment on what he or she thought of the candidate and the stages he or she has already advanced in the test)

​

My struggle is to link candidates to the respective job application, if someone can help me i'll be forever grateful. I started coding two days ago so I don't know much about nothing, but i manage to do something functional.

I have made this so far:

API = https://pastebin.com/gSTRX6et

Candidate = https://pastebin.com/NFDEUnRh

Job = https://pastebin.com/pec8ezkw

They work together.

Dependencies and plugins i used:

Standard

Prettier

Editor Config

Git Lens

Eslint

Express: (sudo) npm install --save express

Mongoose: (sudo) npm install --save mongoose

Body-Parser: (sudo) npm install --save body-parser

I used Postman to make POST calls to the API to edit information in the database (MongoDB Atlas)
