Advanced Features Updater

Overview

Safely implement Intermediate & Advanced features in backend/frontend:

• Add priorities, tags, search/filter/sort to Task model & API
• Implement recurring tasks logic (auto-reschedule on complete)
• Add due dates + reminders (publish event on due date)
• Extend UI forms, list views, filter UI
• Use Dapr Pub/Sub for event publishing (no direct Kafka code)
• Always reference constitution.md v5.0 & task ID

Pre-execution

Before making changes, ask: "Confirm feature spec approved?"

Post-execution

After changes: Run basic tests (add task, filter, recurring create)

Implementation Guidelines

1. Task Model Extensions

• Extend the existing SQLModel Task model with:
  • priority field (enum: low, medium, high, urgent)
  • tags field (JSON/array field for categorization)
  • due_date field (datetime for deadlines)
  • recurrence_pattern field (JSON for recurring tasks)
  • notification_settings field (JSON for reminder preferences)

2. API Endpoints

• Add new endpoints for advanced filtering and sorting
• Implement recurrence handling endpoints
• Add notification/reminders API
• Maintain backward compatibility with existing endpoints
• Ensure proper validation for all new fields

3. Recurring Tasks Logic

• Implement auto-rescheduling when recurring tasks are completed
• Handle different recurrence patterns (daily, weekly, monthly)
• Preserve task properties in recurring instances
• Manage recurrence termination conditions

4. Due Dates & Reminders

• Add due date functionality with proper datetime handling
• Implement reminder system that publishes events on due dates
• Create notification settings for customizing reminders
• Handle timezone considerations for due dates

5. Frontend Implementation

• Enhance UI forms to support new task properties
• Add filter UI for searching and sorting tasks
• Implement priority and tag selection interfaces
• Create recurrence pattern selection UI
• Add due date picker and reminder settings panel

6. Dapr Pub/Sub Integration

• Use Dapr Pub/Sub for all event publishing
• Publish reminder-due events when tasks reach due date
• Ensure proper event schemas and versioning
• Handle event publishing failures gracefully

7. Testing Protocol

• Run basic tests after implementing changes:
  • Add task with all new properties
  • Test filtering and sorting functionality
  • Create and complete recurring tasks
  • Verify reminder event publishing
• Validate that existing functionality remains intact

8. Documentation & Compliance

• Reference constitution.md v5.0 for implementation standards
• Ensure all changes align with task specifications
• Maintain proper code documentation
• Follow security best practices for all new features
