README: A multi-tenant SaaS school management system built with Django, providing comprehensive tools for managing academic operations, student records, and assessments across multiple schools. The platform features PostgreSQL schema-based multi-tenancy for complete data isolation, RESTful APIs with OpenAPI documentation, and bilingual support for Arabic and English interfaces. Architected a PostgreSQL schema-based multi-tenancy system using django-tenants with automatic tenant routing via subdomain detection and custom middleware, ensuring complete data isolation at the database level. Engineered a tenant-aware JWT authentication system with custom middleware that validates tokens against the current tenant schema, preventing cross-tenant data access across all API endpoints. Implemented complex academic year rollover functionality with atomic transactions, automatically cloning grades, sections, and subject configurations while preserving data integrity and referential consistency. Built a sophisticated exam scheduling system with comprehensive validation logic, including conflict detection, date range validation, school hours verification, and max marks constraint checking with dry-run validation endpoints. Designed nested RESTful API architecture with hierarchical routes and bulk upsert operations for marks and attendance, enabling efficient atomic transactions that process hundreds of records in single requests. Containerized the application with multi-stage Docker builds and Docker Compose orchestration, deploying to a Linux VPS with automated deployment scripts, Gunicorn production server configuration, and Makefile commands for migrations, backups, and service management.
