About This Architecture

Django-based course assignment notification flow triggered by post_save signals when admins assign courses or learning paths to employees. The system validates user opt-in preferences and course details before routing through email_service.py to an SMTP mail server, with comprehensive error handling and admin alerting for critical failures. This architecture demonstrates event-driven notification patterns with preference validation and graceful degradation. Fork this diagram on Diagrams.so to customize SMTP configuration, add queue-based delivery, or integrate alternative notification channels like SMS or Slack. The signal-based trigger ensures notifications fire automatically without polling, reducing latency and database load.
