|
|
|
|
**Discussion service with 9 async CRUD operations for discussions, rounds, and messages using selectinload eager loading**
|
|
|
|

|
|
|
|
- **Duration:** 2 min
|
|
- **Started:** 2026-01-16T19:24:14Z
|
|
- **Completed:** 2026-01-16T19:26:56Z

## Accomplishments
|
|
|
|
- Created discussion service following established service layer pattern
|
|
- Implemented 5 discussion operations: create, get (with eager loading), get_active, list, complete
|
|
- Added 4 round/message operations: create_round, get_current_round, create_message, get_round_messages
|
|
- Used selectinload for eager loading rounds→messages to avoid N+1 queries
|
|

|
## Task Commits
|
|
|
|
Each task was committed atomically:
|
|
|
|
1. **Task 1: Create discussion service with CRUD operations** - `3258c3a` (feat)
|
|
2. **Task 2: Add round and message operations** - `baf02bb` (feat)
|
|
|
|
## Files Created/Modified
|
|
|
|
- `src/moai/core/services/discussion.py` - Discussion, Round, Message CRUD operations (9 async functions)
|
|
- `src/moai/core/services/__init__.py` - Updated exports
|
|
|
|
## Decisions Made
|
|
|
|
- Used selectinload for eager loading rounds→messages→consensus to prevent N+1 queries
|
|
- get_discussion includes consensus in eager loading for future phase 6
|
|
- get_current_round orders by round_number desc with limit 1 for efficiency
|
|
|
|
## Deviations from Plan
|
|
|
|
None - plan executed exactly as written.
|
|
|
|
## Issues Encountered

|
## Next Phase Readiness

|
|
|
- Discussion service ready for /open and /discuss command handlers
|
|
- Round/message operations available for multi-model discussion flow
|
|
- Ready for 05-02-PLAN.md (open mode handler)
