Reports Page Implementation Summary

Overview

The Reports page has been successfully connected to real API endpoints, replacing all hardcoded sample data with live data from the database.

Changes Made

1. Backend API (backend/api/endpoints/reports.py)

Created comprehensive reports endpoints:

• GET /api/v1/reports/stats - Overall statistics

  • Total reports count
  • Average test score
  • Shortlisted candidates count
  • Rejected candidates count

• GET /api/v1/reports/pass-fail - Test pass/fail statistics

  • Passed tests count
  • Failed tests count
  • Total tests count

• GET /api/v1/reports/candidate-reports - Detailed candidate reports

  • Candidate information
  • Test scores
  • Interview scores
  • Recommendations (Strong Hire, Shortlist, Maybe, Reject)
  • Application dates

• GET /api/v1/reports/skills-analysis - Skills analysis across candidates

  • Top 10 skills by frequency
  • Average scores per skill
  • Candidate count per skill

• GET /api/v1/reports/performance-overview - Hiring performance metrics

  • Hiring rate percentage
  • Average time to hire (days)
  • Quality score (0-5 scale)
  • Total candidates and hired count

2. API Router Registration (backend/api_app.py)

• Imported reports router
• Registered at /api/v1/reports prefix

3. Frontend API Service (frontend/src/services/api.js)

Added methods for all reports endpoints:

• getReportStats()
• getPassFailStats()
• getCandidateReports(skip, limit)
• getSkillsAnalysis()
• getPerformanceOverview()

4. Reports Page (frontend/src/pages/Reports.jsx)

Completely refactored to use real data:

• Added state management for all data sections
• Implemented fetchReportsData() to load all data in parallel
• Added loading state with spinner
• Connected all components to real API data
• Added error handling
• Placeholder handlers for Export and Generate Report buttons

Bug Fixes

• Fixed Interview model field reference: Changed overall_rating to overall_score (0-100 scale)
• Fixed interview score calculation in candidate reports
• Fixed quality score calculation in performance overview

Testing

Created backend/test_reports_api.py to verify all endpoints:

• All 5 endpoints tested successfully
• Returns real data from database
• Proper authentication handling

Data Flow

1. User navigates to Reports page
2. Frontend calls all 5 API endpoints in parallel
3. Backend queries database for relevant data
4. Data is processed and formatted
5. Frontend displays data in charts and tables

Current Data Available

Based on test results:

• 5 total reports
• Average score: 11.5%
• 1 shortlisted candidate
• 0 rejected candidates
• 2 completed tests (0 passed, 2 failed)
• Skills tracked: Python, Django, Node.js, etc.
• 6 total candidates in system

Next Steps (Optional Enhancements)

1. Implement Export functionality (CSV/PDF)
2. Implement Generate Report functionality
3. Add date range filters
4. Add real-time updates
5. Add more detailed analytics
6. Add comparison charts (month-over-month, etc.)

Files Modified

• backend/api/endpoints/reports.py (created)
• backend/api_app.py (updated)
• frontend/src/services/api.js (updated)
• frontend/src/pages/Reports.jsx (updated)
• backend/test_reports_api.py (created)

How to Test

1. Ensure backend is running: python backend/api_app.py
2. Ensure frontend is running: npm run dev in frontend folder
3. Login to the application
4. Navigate to Reports page
5. All data should load from the database
6. Or run: python backend/test_reports_api.py to test API directly

Status

✅ Complete - Reports page is fully functional with real data
