Sleeper Bus Ticket Booking System 🚌

A premium Django-based booking platform for intercity sleeper bus travel, featuring real-time seat selection, meal integration, and AI-powered booking predictions.

✨ Defined Features

1. Backend API Implementation: Robust RESTful API using Django REST Framework with ViewSets and Routers.
2. Visual Seat Selection: Interactive map distinguishing Lower (L1-L15) vs. Upper (U1-U15) deck sleeper seats.
3. Smart Prediction Logic: Mock AI algorithm calculating a "Confirmation Probability %" based on user intent signals (meal choice, group size).
4. Concurrency Handling: Prevents double-booking using Atomic Transactions and Row Locking.
5. Integrated Add-ons: Seamless meal booking (Veg/Snack) affecting total fare calculation.

🧪 Test Cases

Functional Tests

• Seat Booking Flow: User selects seat -> Fills Passenger Details -> Booking Creation Success.
• API Validation: Rejects invalid phone numbers (non-10 digits) and names (special characters).
• Race Condition Check: Concurrent requests for the same seat results in one success and one failure.

Edge Cases

• Zero Availability: System gracefully handles full bus scenario.
• Data Integrity: Checks ensuring Seat status updates strictly match Booking records.
