|
|
|
|
**Date Completed:** 2025-01-08 (Evening - 7:24 PM)
|
|
**Status:** 100% Complete - Production Ready
|
|
|
|
---
|
|
|
|
## What Was Accomplished
|
|
|
|
### Queue Template Consolidation ✅
|
|
|
|
**Problem Identified:**
|
|
- Two duplicate queue display templates existed:
|
|
- `queue_display.html` - Integrated with base.html, grid layout
|
|
- `queue_monitor.html` - Standalone HTML, list layout, WebSocket support
|
|
|
|
**Solution Implemented:**
|
|
- Created enhanced `queue_monitor.html` combining best features from both
|
|
- Removed duplicate `queue_display.html` template
|
|
- Backed up old `queue_monitor.html` as `queue_monitor_old.html`
|
|
|

## Migration Notes
|
|
|
|
### For Existing Deployments
|
|
|
|
**If using queue_display.html:**
|
|
1. Update URL to point to queue_monitor view
|
|
2. No code changes needed (same view function)
|
|
3. Enhanced features automatically available
|
|
|
|
**If using queue_monitor.html:**
|
|
1. No changes needed
|
|
2. Enhanced features automatically available
|
|
3. Old template backed up as queue_monitor_old.html
|
|
|
|
### URL Patterns
|
|
- No URL changes required
|
|
- Both views use same endpoint: `/queue/<pk>/monitor/`
|
|
- View function: `queue_monitor_view(request, pk)`
|
|
