This tutorial explores the implementation of advanced authorization models, Relationship-Based Access Control (ReBAC) and Attribute-Based Access Control (ABAC), in a blog platform using Strapi and Next.js. It guides users through setting up permissions based on user-resource relationships and dynamic attributes, leveraging Permit.io for scalable authorization. The tutorial details configuring Strapi content types, syncing user data, and assigning roles to implement ReBAC, while ABAC rules are applied to enforce conditions like subscription status and regional content access. The tutorial also covers integrating these controls into both backend and frontend components, enhancing the platform's security and control over content access. The approach ensures a robust, maintainable permission system suitable for content-driven applications.
