FastAPI & Next.js project: Flight Booking App With DevOps. Day 1 - 100 - My Models Keep Changing. Time To Learn Alembic | FastAPI Migrations | Flight Booking Engine | Day 40

I’ve been updating the models… and VS Code Copilot “just makes Alembic work.” But now it’s time to actually understand it — for real. 🧠⚡ In Day 40, we finally dive deep into Alembic, the migration tool behind FastAPI + SQLAlchemy, and use it to properly evolve the Booking model so it can handle more real-world flight data. No magic. No guessing. Just learning Alembic properly — live. 💡 In this session: • Understand what Alembic really is and why you need it • Generate migrations the right way • Apply migrations without breaking your database • Modify and upgrade the Booking model with real fields • Fix common Alembic errors developers always run into By the end, you’ll know exactly how your migrations work — and why they matter for a production-grade Flight Booking Engine. 📂 GitHub Repo: 👉 https://github.com/KNehe/aero_bound_ventures-public.git 📘 Playlist: 👉 https://www.youtube.com/playlist?list=PLdtwawCR2QjmdfhM-7SzDOVGop373bbgW 🔥 Subscribe for fullstack FastAPI + Next.js builds — real code, real problems, real solutions. #FastAPI #Alembic #Nextjs #FlightBookingApp #FullStack
