The alert_processor service was crashing with:
ImportError: cannot import name 'get_db' from 'shared.database.base'
Root cause: alerts.py was using Depends(get_db) pattern which doesn't exist
in shared.database.base.
Fix: Refactored alerts.py to follow the same pattern as analytics.py:
- Removed Depends(get_db) dependency injection
- Each endpoint now creates a DatabaseManager instance
- Uses db_manager.get_session() context manager for database access
This matches the alert_processor service's existing architecture in analytics.py.
Implemented missing alert endpoints that the dashboard requires for
health status and action queue functionality.
Alert Processor Service Changes:
- Created alerts_repository.py:
* get_alerts() - Filter alerts by severity/status/resolved with pagination
* get_alerts_summary() - Count alerts by severity and status
* get_alert_by_id() - Get specific alert
- Created alerts.py API endpoints:
* GET /api/v1/tenants/{tenant_id}/alerts/summary - Alert counts
* GET /api/v1/tenants/{tenant_id}/alerts - Filtered alert list
* GET /api/v1/tenants/{tenant_id}/alerts/{alert_id} - Single alert
- Severity mapping: "critical" (dashboard) maps to "urgent" (alert_processor)
- Status enum: active, resolved, acknowledged, ignored
- Severity enum: low, medium, high, urgent
API Server Changes:
- Registered alerts_router in api_server.py
- Exported alerts_router in __init__.py
Procurement Client Changes:
- Updated get_critical_alerts() to use /alerts path
- Updated get_alerts_summary() to use /alerts/summary path
- Added severity mapping (critical → urgent)
- Added documentation about gateway routing
This fixes the 404 errors for alert endpoints in the dashboard.
