Release v5.2.1 · CESNET/cesnet_service_path_plugin

[5.2.1] - 2025-11-07

Topology Visualization: Interactive network topology visualization using Cytoscape.js
- Visual representation of segment connections and circuit terminations
- Multi-topology support for service paths with multiple segments
- Automatic topology generation for both segments and service paths
- Clean NetBox Blue styled visualization with gradients and shadows
- Interactive topology viewer with hover tooltips showing node details
- Topology visualization integrated into segment and service path detail views
- Topology visualization added to circuit detail pages showing related segments/service paths
- Toggle between multiple topologies when segment belongs to multiple service paths
Commitment End Date Tracking: Enhanced financial commitment monitoring
- Automatic calculation of commitment end date based on install date and commitment period
- Color-coded commitment status indicators:
  - Red: More than 30 days until end
  - Orange: Within 30 days of end
  - Green: Commitment period has ended
  - Gray: No commitment period set
- Interactive tooltips showing days remaining until commitment end
- Visual feedback for commitment periods that have ended
- Commitment end date displayed in segment detail view with badge styling
- GraphQL API support for commitment end dates with ISO format

Circuit Extensions Refactoring: Improved code organization
- Renamed CircuitKomoraSegmentExtension to CircuitSegmentExtension for better naming consistency
- Enhanced circuit detail view with topology visualization support
- Better separation of concerns in template content extensions
- Circuit pages now show topology visualizations for associated segments
Currency Field Enhancement: Made charge_currency field required
- Removed default currency value to ensure explicit currency selection
- Migration 0031 updates currency field constraints
- Currency must now be explicitly set when creating financial information
- Prevents accidental use of default currency when not intended
Table Improvements: Enhanced data presentation
- Circuit column in SegmentCircuitMappingTable now orders by CID instead of name
- Improved ordering logic for better data organization and searchability
Version Update: Updated to version 5.2.1 in pyproject.toml

Added missing python-dateutil dependency to pyproject.toml for date calculations
Improved commitment end date calculation with proper timezone handling using django.utils.timezone
Enhanced tooltip rendering with proper Bootstrap integration
Fixed tooltip data attributes for proper display of commitment information

New utility module utils_topology.py with TopologyBuilder class for generating network graphs
Cytoscape.js (v3.28.1) integration for advanced graph visualization
Reusable topology visualization templates
Support for multiple topologies on single page with tab switching functionality
Topology data stored as JSON and rendered client-side for performance
Color-coding system for commitment status based on time remaining (30-day threshold)
New GraphQL field resolver for commitment_end_date with ISO format output
Template extensions now check for service path membership to generate appropriate topologies

Migration 0031: Updates charge_currency field to remove default value - requires explicit currency selection
New Dependencies: Added python-dateutil for relativedelta calculations in commitment period tracking
Template Updates: New topology visualization templates require Cytoscape.js CDN (included automatically)
API Changes: GraphQL API now includes commitment_end_date field in SegmentFinancialInfoType

Run migrations: python manage.py migrate cesnet_service_path_plugin
Install new dependency: pip install python-dateutil (or upgrade plugin package)
Update existing financial records to set currency explicitly if using default
Refresh browser cache to load new topology visualization assets
