FastAPI RBAC - Full Implementation Tutorial

This guide explains how to implement role-based access control (RBAC) in a FastAPI application to manage user permissions and access. The tutorial covers setting up a contact management app where administrators and regular users have different capabilities. It integrates with Permit.io for fine-grained access control and defines user roles, permissions, and secure routes using the FastAPI framework, supported by technologies like PostgreSQL, SQLAlchemy, and Uvicorn.
