# Change: Improve File Display in Chat and Fix Timezone Issues
|
|
|
|
## Why
|
|
Currently, uploaded files and images only appear in the "file drawer" sidebar, making it difficult to understand the context of when and why a file was uploaded. This also impacts AI report generation, as the AI cannot associate files with the conversation context. Additionally, some parts of the application still display times in GMT+0 instead of GMT+8.
|
|
|
|
## What Changes
|
|
- **BREAKING**: Message creation when uploading files - files now generate a linked message in chat
|
|
- Display uploaded files and images inline in the chat conversation
|
|
- Add image preview functionality with lightbox
|
|
- Show image thumbnails in chat messages (expandable to full size)
|
|
- Non-image files display with file type icons
|
|
- Update upload interface to show preview before sending
|
|
- Update AI report data collection to include file context (associated messages)
|
|
- Fix remaining GMT+0 timestamp displays to use GMT+8
|
|
|
|
## Impact
|
|
- Affected specs: file-storage, realtime-messaging, ai-report-generation
|
|
- Affected code:
|
|
- Backend: `app/modules/file_storage/router.py`, `app/modules/realtime/` (message creation on upload)
|
|
- Backend: `app/modules/report_generation/services/report_data_service.py`
|
|
- Frontend: `frontend/src/pages/RoomDetail.tsx`
|
|
- Frontend: New components `FileMessage.tsx`, `ImagePreview.tsx`
|
|
- Database: May need migration to add `message_id` FK to `tr_room_files`
