Legacy System Removal Summary

Overview

Successfully removed the legacy station/pump configuration system and fully integrated the tag-based metadata system throughout the Calejo Control application.

Changes Made

1. Configuration Manager (src/dashboard/configuration_manager.py)

  • Removed legacy classes: PumpStationConfig, PumpConfig, SafetyLimitsConfig
  • Updated ProtocolMapping model: Added validators to check station_id, equipment_id, and data_type_id against the tag metadata system
  • Updated HardwareDiscoveryResult: Changed from legacy class references to generic dictionaries
  • Cleaned up configuration methods: Removed legacy configuration export/import methods

2. API Endpoints (src/dashboard/api.py)

  • Removed legacy endpoints: /configure/station, /configure/pump, /configure/safety-limits
  • Added tag metadata endpoints: /metadata/stations, /metadata/equipment, /metadata/data-types
  • Updated protocol mapping endpoints: Now validate against tag metadata system

3. UI Templates (src/dashboard/templates.py)

  • Replaced text inputs with dropdowns: For station_id, equipment_id, and data_type_id fields
  • Added dynamic loading: Dropdowns are populated from tag metadata API endpoints
  • Updated form validation: Now validates against available tag metadata
  • Enhanced table display: Shows human-readable names with IDs in protocol mappings table
  • Updated headers: Descriptive column headers indicate "Name & ID" format

4. JavaScript (static/protocol_mapping.js)

  • Added tag metadata loading functions: loadTagMetadata(), populateStationDropdown(), populateEquipmentDropdown(), populateDataTypeDropdown()
  • Updated form handling: Now validates against tag metadata before submission
  • Enhanced user experience: Dropdowns provide selection from available tag metadata
  • Improved table display: displayProtocolMappings shows human-readable names from tag metadata
  • Ensured metadata loading: loadProtocolMappings ensures tag metadata is loaded before display

5. Security Module (src/core/security.py)

  • Removed legacy permissions: configure_safety_limits permission removed from ENGINEER and ADMINISTRATOR roles

Technical Details

Validation System

  • Station Validation: station_id must exist in tag metadata stations
  • Equipment Validation: equipment_id must exist in tag metadata equipment
  • Data Type Validation: data_type_id must exist in tag metadata data types

API Integration

  • Metadata Endpoints: Provide real-time access to tag metadata
  • Protocol Mapping: All mappings now reference tag metadata IDs
  • Error Handling: Clear validation errors when tag metadata doesn't exist

User Interface

  • Dropdown Selection: Users select from available tag metadata instead of manual entry
  • Dynamic Loading: Dropdowns populated from API endpoints on page load
  • Validation Feedback: Clear error messages when invalid selections are made
  • Human-Readable Display: Protocol mappings table shows descriptive names with IDs
  • Enhanced Usability: Users can easily identify stations, equipment, and data types by name

Benefits

  1. Single Source of Truth: All stations, equipment, and data types are defined in the tag metadata system
  2. Data Consistency: Eliminates manual entry errors and ensures valid references
  3. Improved User Experience: Dropdown selection is faster and more reliable than manual entry
  4. System Integrity: Validators prevent invalid configurations from being saved
  5. Maintainability: Simplified codebase with unified metadata approach

Testing

All integration tests passed:

  • ✅ Configuration manager imports without legacy classes
  • ✅ ProtocolMapping validators check against tag metadata system
  • ✅ API endpoints use tag metadata system
  • ✅ UI templates use dropdowns instead of text inputs
  • ✅ Legacy endpoints and classes completely removed

Migration Notes

  • Existing protocol mappings will need to be updated to use valid tag metadata IDs
  • Tag metadata must be populated before creating new protocol mappings
  • The system now requires all stations, equipment, and data types to be defined in the tag metadata system before use
