From 59fde726f987e23cbcd7b7e5d37a2e9a830630fb Mon Sep 17 00:00:00 2001 From: Abidoyesimze Date: Sat, 24 Jan 2026 13:52:06 +0100 Subject: [PATCH 1/4] feat: implement attendance analytics and reporting functions MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Implement comprehensive analytics functions for attendance data including time tracking, frequency analysis, and pattern recognition capabilities. Changes: - Add analytics data structures (DateRange, TimePeriod, UserAttendanceStats, AttendanceFrequency, PeakHourData, DayPattern) to common_types - Add attendance summary structures (AttendanceSummary, AttendanceReport, SessionPair) to manage_hub types - Implement 9 analytics functions in attendance_log module: * get_attendance_summary() - summary with date range filtering * get_time_based_attendance() - daily/weekly/monthly queries * calculate_attendance_frequency() - frequency metrics * get_user_statistics() - comprehensive user stats * analyze_peak_hours() - hourly pattern analysis * analyze_day_patterns() - weekly pattern analysis * calculate_total_hours() - time conversion utility * calculate_average_daily_attendance() - daily averages * Helper functions for filtering and session parsing - Add 8 public contract endpoints in lib.rs for analytics access - Add new error codes: InvalidDateRange, NoAttendanceRecords, IncompleteSession Features: - Smart session matching (clock-in/clock-out pairing) - Date range filtering with validation on all analytics functions - Peak hours identification (0-23) with percentage distribution - Day pattern analysis (0-6) with percentage distribution - Performance optimizations for large datasets - Comprehensive error handling and validation All acceptance criteria met: ✓ Date range filtering on all analytics functions ✓ Time-based queries (daily, weekly, monthly) ✓ Attendance frequency calculations ✓ User statistics (total hours, average daily attendance) ✓ Performance optimizations for large datasets ✓ Pattern analysis (peak hours and days) ✓ Report generation functions Compiled successfully with no errors or warnings. --- contracts/common_types/src/lib.rs | 5 +- contracts/common_types/src/types.rs | 140 +++++++ contracts/manage_hub/src/attendance_log.rs | 446 ++++++++++++++++++++- contracts/manage_hub/src/errors.rs | 3 + contracts/manage_hub/src/lib.rs | 181 ++++++++- contracts/manage_hub/src/types.rs | 36 +- 6 files changed, 805 insertions(+), 6 deletions(-) diff --git a/contracts/common_types/src/lib.rs b/contracts/common_types/src/lib.rs index 1db88fd..fc82b9d 100644 --- a/contracts/common_types/src/lib.rs +++ b/contracts/common_types/src/lib.rs @@ -9,8 +9,9 @@ mod types; // Re-export all types pub use types::{ -
