This is our repository for the CS50 course Final Project
The project's goal is to introduce a way to control your plastic footprint everytime you shop.
Striving for a more conscious World, awareness of our footprint is essential. Getting past last century materials is walking in that direction.
We are developping a tool to track and regulate plastic consumption. This tool shall register individuals or households granting them a free of charge plastic balance. In collaboration with shops and retailers, the plastic weight of products included in one shopping transaction is subtracted from the current balance. For this process to be accurate, every selling item shall be registered in a knowledge base.
We've decided to create a Web App using Django and a PostGres database. The idea is the user to interact with a GUI fetching its data or executing some operations that will represent CRUD operations in the DB.
Running the project from the beggining
-
Create a user postgres if it does not exist
createuser -s postgres -
Create a DB named plastic_tracker
createdb plastic_tracker -
Apply the migrations to your DB
python manage.py migrate
You will need to have installed python libraries django, python-dotenv, django-materializecss-form and psycopg2 -
Run the webserver
python manage.py runserver
The application allows two flows:
- Creating a user & check user details
- Register a user's shopping list
The user creation takes you to a form where one has to introduce user's data, including a unique identifier (per example, a social number) It is possible to check the User Details (where the current plastic balance is displayed) through a search by ID. Each registred client can acces its own page anytime and check the current monthly plastic balance.
There is a shop page that is responsible for registring a client's shopping list. To register a shopping list, one has to introduce a registered User ID. A page to register the shopping items is displayed as well as a "payment" button that will sum all the items plastic weight and subtract it from the User's balance. Each item has a price as well as a plastic weight, which is accumulated with all the monthly shopping and optionally taxed according to a pre-defined table
- Create a more fair initial plastic balance taking in consideration families
- Define fees for different levels of plastic "debt"
