INVOYGER (link - https://invoyger.rohitj.dev/)

Role-based Django online marketplace with separate customer/admin workflows, cart + checkout pipeline, order lifecycle, and downloadable PDF invoices.

Why This Project Stands Out

• Built as a modular multi-app Django architecture, not a single monolith
• Real marketplace flow: browse -> cart -> checkout -> order -> invoice
• Role-based authorization with dedicated dashboards
• Invoice PDFs generated server-side using ReportLab
• Clean foundation for scaling into production (payments, shipping, analytics)

Features

• Authentication + role profiles (Customer, AdminUser)
• Product CRUD with image upload, stock, active/inactive status
• Category filtering (Men, Women, Kids, Accessories, Universal)
• Persistent cart and quantity updates
• Checkout that snapshots product data into order items
• Admin order management and status updates
• PDF invoice download for customer and admin

Tech Stack

• Python, Django 6
• SQLite (dev DB)
• Django Templates + HTML/CSS
• ReportLab (PDF generation)
• Pillow (image support)

Architecture

|-- manage.py
|-- authsys/         # settings, root urls, wsgi/asgi
|-- accounts/        # auth + role models
|-- adminpanel/      # admin dashboard, product/order controls

Data Model (Core)

• Product: catalog item with price, stock, category, image, active status
• cart + cartitem: user cart persistence and quantities
• Order: generated order_id, status, total, timestamps
• OrderItem: immutable snapshot (product_name, price, quantity, line_total)
• Customer / AdminUser: role profiles linked to User

Local Setup

git clone <your-repo-url>
cd authsys
python -m venv .venv

Windows (PowerShell):

.venv\Scripts\Activate.ps1

Install deps and run:

pip install django reportlab pillow
python manage.py migrate
python manage.py runserver

App URL: http://127.0.0.1:8000/

Main Routes

• / public home
• /signup/, /login/, /logout/
• /shop/, /shop/cart/
• /orders/checkout/
• /orders/order-success/<order_id>/
• /orders/invoice/<order_id>/
• /adminpanel/
• /adminpanel/orders/

Production Notes

• DEBUG=True and ALLOWED_HOSTS=['*'] are development settings
• Admin signup code in accounts/views.py is hardcoded; move to env var
• Use PostgreSQL/MySQL + proper secrets management for deployment

Roadmap

• Add requirements.txt with pinned versions
• Add automated tests for checkout + role access
• Add CI pipeline (lint + tests)
• Integrate payment gateway and shipping updates
• Harden security settings and deployment config
