This commit refactors the LMS architecture from a flat 2-tier structure to a granular 3-tier structure to support better course organization, while ensuring zero downtime or breaking changes for existing frontend clients.
Introduced `CourseChapter` model as the new grouping layer
2 endpoints (`/v2/.../lessons/`): Introduced new `LessonListV2APIView` and `CourseChapterSerializer` to return the new nested JSON schema (Chapters -> Lessons) for the upcoming accordion UI.
Created robust `migrate_lessons_to_chapters` management command.
Registered `CourseChapter` and added `CourseChapterInline` to `CourseAdmin` for seamless content management.
- Enhanced session handling by checking for active sessions before creating a new room in PlugNMeet, reducing unnecessary API calls.
- Implemented logic to reactivate ended sessions and log relevant actions for better traceability.
- Added conditional room creation to avoid duplicate rooms, improving overall efficiency and user experience.
- Updated CourseLiveSessionRoomCreateAPIView to filter out ended sessions by adding `ended_at__isnull=True` in the session creation logic.
- Introduced a new method in CourseLiveSessionTokenAPIView to build centralized metadata for room settings, ensuring client overrides are not permitted and enhancing session configuration consistency.
- Updated CourseLiveSessionRoomCreateAPIView to filter out ended sessions by adding `ended_at__isnull=True` in the session creation logic.
- Introduced a new method in CourseLiveSessionTokenAPIView to build centralized metadata for room settings, ensuring client overrides are not permitted and defining default lock settings and room features.
- Improved room verification logic in CourseLiveSessionTokenAPIView to handle both boolean and string responses for room activity status.
- Added functionality to automatically recreate inactive rooms for professors while denying token issuance for students if the room is inactive.
- Enhanced logging for better traceability of room status and actions taken during token requests.
- Introduced a new method to handle room recreation in PlugNMeet, ensuring sessions can be reactivated when necessary.
- Added TokenAuthentication to allow users to authenticate with a token while still permitting access without authentication.
- Removed redundant debug print statements related to token validation to streamline the code and improve readability.
- Added checks in get_saved_location method to ensure user is authenticated and has location_history attribute before attempting to access it.
- Improved robustness of location retrieval logic to prevent errors for unauthenticated users.
- Updated permission classes to allow any user for GET requests, enhancing accessibility.
- Added detailed logging for both GET and POST requests to track request data and processing steps.
- Improved handling of user authentication status in log messages for better traceability.
- Added detailed logging for GET and POST requests in CourseOnlineClassTokenValidateAPIView to track user actions and course validation.
- Improved logging in OnlineClassTokenManager for token generation, storage, retrieval, and deletion processes, including error handling for Redis interactions.
- Commented out the entire class and method definitions for the PlugNMeetWebhookAPIView to facilitate debugging and future modifications.
- Retained the structure and docstrings for clarity on event handling and signature verification.
- Enhanced debug logging for signature verification to assist in identifying issues during development.
- Updated permission logic for course management.
- Simplified room ID setup and metadata handling.
- Enhanced PlugNMeetClient integration for room creation and token generation.
- Improved error handling and logging for API interactions.
- Adjusted response structure to include the generated access token for frontend use.
- Updated the _verify_webhook_signature method to include detailed debug logging for better traceability of signature verification issues.
- Improved error messages for missing headers and configuration settings.
- Added checks for empty request bodies to assist in identifying middleware issues.
- Adjusted logging to prevent sensitive information exposure while still providing useful debugging information.
- Implemented validation and permission checks for course management.
- Updated room ID generation to comply with NATS rules by prefixing with 'room-'.
- Integrated JWT token generation for user access to live sessions.
- Improved error handling for PlugNMeet API interactions.
- Enhanced response structure to include access token for frontend connectivity.
