Django Authorization: An Implementation Guide

Django, a versatile framework for web application development, has a default role-based permission system that may not suffice for complex applications requiring fine-grained access control. To address this, the guide details implementing Relationship-Based Access Control (ReBAC) and Attribute-Based Access Control (ABAC) in Django using Permit.io for a more nuanced authorization approach. ReBAC enhances traditional role-based models by factoring in user-resource relationships, while ABAC evaluates user, resource, and environmental attributes to make authorization decisions. The guide demonstrates these advanced models through an E-Learning demo application, where access to courses is determined by relationships (such as instructor or student roles) and dynamic attributes like course level, enrollment status, and geographic restrictions. By setting up ReBAC and ABAC policies, the demo application facilitates comprehensive access control, ensuring permissions align with user roles and attributes in real time, without requiring code redeployment. This integration allows for sophisticated permission management, suitable for modern educational platforms demanding precise access control.
