Shot Project ID Soft Deletion Service Update

Overview

This document describes the updates made to the soft deletion services to ensure project_id is properly preserved during soft deletion and recovery operations for shots.

Changes Made

1. Shot Soft Deletion Service (backend/services/shot_soft_deletion.py)

DeletionInfo Class Updates

  • Added project_id field: The DeletionInfo class now includes a project_id field to store the project ID of the shot being deleted.
  • Updated initialization: The get_deletion_info method now populates project_id directly from shot.project_id instead of deriving it from the episode relationship.

Activity Logging Updates

  • Direct project_id usage: The _log_shot_deletion method now uses shot.project_id directly for the activity's project_id field.
  • Enhanced metadata: Added project_id and project_name to the activity metadata for better tracking.

2. Recovery Service (backend/services/recovery_service.py)

DeletedShot Class Updates

  • Added project_id field: The DeletedShot class now includes a project_id field for consistency.

RecoveryInfo Class Updates

  • Added project_id field: The RecoveryInfo class now includes a project_id field to track project information during recovery operations.

Service Method Updates

  • Updated get_deleted_shots: Now populates project_id directly from shot.project_id.
  • Updated preview_shot_recovery: Now includes project_id in the recovery information.
  • Updated _log_shot_recovery: Uses shot.project_id directly and includes project information in activity metadata.

3. Admin Router (backend/routers/admin.py)

API Response Updates

  • Enhanced deleted shots endpoint: The /admin/deleted-shots/ endpoint now includes project_id in the response.
  • Enhanced recovery preview endpoint: The /admin/shots/{shot_id}/recovery-preview endpoint now includes project_id in the response.

Key Benefits

1. Data Integrity

  • Direct relationship: Using shot.project_id directly ensures data integrity and eliminates dependency on episode relationships for project identification.
  • Consistent tracking: Project information is consistently preserved throughout the soft deletion and recovery lifecycle.

2. Performance Improvement

  • Reduced joins: Direct access to project_id reduces the need for complex joins through episode relationships.
  • Faster queries: Project filtering can now use direct project_id comparisons.

3. API Enhancement

  • Complete information: API responses now include both project_id and project_name for better frontend integration.
  • Filtering support: The existing project filtering functionality now works more efficiently with direct project_id access.

Backward Compatibility

All changes maintain backward compatibility:

  • Existing API endpoints continue to work as before
  • Additional fields are added without removing existing functionality
  • Episode relationships are still maintained and used where appropriate

Testing

Test Coverage

  • Unit tests: Existing soft deletion service tests continue to pass
  • Integration tests: New tests verify project_id preservation throughout the deletion/recovery cycle
  • API tests: Tests verify that API endpoints return project_id information correctly

Test Files Created

  1. test_project_id_preservation_simple.py - Tests core project_id preservation functionality
  2. test_admin_api_project_id.py - Tests API endpoint responses (requires running server)

Requirements Validation

This implementation satisfies the following requirements from the specification:

Requirement 4.5

"WHEN soft deleting shots, THE VFX_System SHALL preserve project_id information for recovery operations"

✅ Satisfied:

  • project_id is preserved in the shot record during soft deletion
  • Recovery operations maintain project_id consistency
  • All related data maintains project relationships

Additional Benefits

  • Enhanced logging: Activity logs now include complete project information
  • Improved debugging: Project context is available in all deletion/recovery operations
  • Better admin tools: Admin interfaces have access to project information for better management

Migration Notes

No database migration is required for these changes as they work with the existing project_id column that was added in the previous migration. The changes are purely at the service and API layer to ensure proper utilization of the existing project_id field.

Future Enhancements

Potential future improvements could include:

  • Adding project-specific deletion policies
  • Enhanced project-based recovery filtering
  • Project-scoped deletion statistics and reporting
