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.
updated missing lazy text keywords for django messages in related models
updated .po file and translate the empty values in it
add a unfold translations file to keep the unfold messages whenever we run makemasseges.
models updated with lock values , course model has two group lock and professor lock options
serializers updated with new fields
admin panel updated for this new fields
signals configured to automatically lock/unlock the chatrooms related to courses based on the boolean values of course
to chat room page navigation shortcut is updated with unfold action buttons instead of html files
- add recorded_file FileField to CourseLiveSession with migration
- add serializers for recording upload and metadata
- add PATCH endpoint to create a recording for latest session:
/<int:course_id>/live-sessions/recorded-file/
- enforce can_manage_course permission and return recording metadata
- update urls and views; use FileFieldSerializer for file handling
- add CourseLiveSession.room_id field with unique index
- introduce LiveSessionRoomCreateSerializer and LiveSessionTokenSerializer
- add URLs for room creation and token:
- <slug>/online/room/create
- online/room/token
- enhance token validation metadata with:
- can_create_live_session, can_join_live_session flags
- live session context (active_room_id, timings, details)
- improve logging and token error handling in validation flow
- add PlugNMeet configuration settings (URL, API key/secret, timeout)
This introduces the endpoints and data structures needed to create and
join live sessions, and surfaces richer metadata for frontend usage. A
database migration is required for the new model field and index.
- create CourseLiveSession, LiveSessionUser, LiveSessionRecording with
indexes and unique constraints
- register new models in admin and add UNFOLD navigation entries
- update token validation to derive is_online and include
livesession_started_at, livesession_ended_at, and can_start_online_class
- extend online class entry flow documentation with new fields
- add migration for new live session tables
- Altered the thumbnail field in the Course model to remove null and blank options, making it mandatory.
- Added a migration to reflect this change in the database schema.
