Elevator System

!(https://github.com/SolomonNewCentury/Elevator)

A elevator system which goes up, down and stops built with Django(Django Rest Framework including Viewsets, Serializers and etc.)

Architecture

• When a user logs in, the frontend downloads the elevator list set already. In first case, there will be no elevator set in elevator list
• So, users can set the number of elevators by clicking format button bellow login button. Then this elevator system is initialized. While using this system, users can initialize system like this.
• After that, elevators are displayed in interface.
• Each elevator is divided into two status: opened or closed
• Each elevator contains follow things: . floor that elevator is located . floor to go up or down based on request of user . status to mark whether elevator is in maintenance or not . status to mark whether elevator is operational or not . status to mark whether elevator has to go up or down . status to mark whether elevator is running or not
• Users can change all of these things by clicking Edit button
• Users can use only elevator that is operational and not in maintenance, not in running and set clear destination

Requests

update 04/06/19

• using pipenv for package management
• move to Channels 2
• use redis as the channel layer backing store. for more information, please check channels_redis

Database

For this system, I have used postgreSQL. In using of this, you has to consider about version of postgreSQL and django. I used django 5.0 and postgreSQL 16.1

Assumptions

Because of time constraints this project lacks of:

• User Sign-Up / Forgot Password
• Good Test Coverage
• Better Comments / Documentation Strings
• Frontend & Backend Tests
• Modern Frontend Framework (like React)
• Proper UX / UI design (looks plain bootstrap)
