From faa4d89152215feddccb7076f017772ad61ece9b Mon Sep 17 00:00:00 2001 From: Stephen Adamson Date: Sat, 7 Mar 2026 16:38:23 +0000 Subject: [PATCH] Implement business logic changes: deposits, no-shows, reservations, approval workflow MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit CHANGES: Phase 1: Schema - Change deposits_required default from 3 to 0 for new users - Add forgiven_no_shows table to track forgiven no-show bookings Phase 2: No-Show Logic (manage.go) - CountUnforgivenNoShows(): Count unforgiven no-shows in 6-month period - ApplyDepositsIfNeeded(): Auto-apply 3 deposits if 2+ no-shows detected - ForgiveNoShowsForUser(): Clear no-shows and reset deposits on full payment Phase 3: Slot Reservation System - Add CleanupOldReservations() to delete 1h+ old reservation blockers - Call cleanup in GetAvailableHours() on each availability check - Delete existing user reservation before creating new booking Phase 4: Minimum Advance Time - Changed from 48h (deposit-only) to 1h (all users) - Now universally enforced at booking creation time Phase 5: Notes-Based Approval Workflow - If booking has notes (not empty) → status = 'pending' (needs approval) - If no notes → status = 'confirmed' (auto-approved) - Uses CASE statement in INSERT for status determination Phase 6: Late Night Lock - After 22:00, non-admin users cannot book next morning before 11:00 - Implemented in GetAvailableHours() via artificial blocker subtraction - Admin users see all times (no restriction) Phase 7: Admin Notifications - Notify admin if booking has notes OR is for same day - All qualifying bookings trigger notification for admin review VERIFICATION: ✓ Build passes: go build -tags dev ./main.go succeeds ✓ All 7 phases implemented as per dev-approved plan ✓ No breaking changes to existing schemas ✓ Backward compatible with existing booking flow --- backend/handlers/bookings/bookings.go | 37 ++++++-- backend/handlers/bookings/manage.go | 98 ++++++++++++++++++++ backend/handlers/scheduling/default-hours.go | 21 +++++ backend/handlers/scheduling/time-blockers.go | 12 +++ init-scripts/init-script.sql | 14 ++- 5 files changed, 173 insertions(+), 9 deletions(-) diff --git a/backend/handlers/bookings/bookings.go b/backend/handlers/bookings/bookings.go index 0761fbf..0578a1f 100644 --- a/backend/handlers/bookings/bookings.go +++ b/backend/handlers/bookings/bookings.go @@ -1111,12 +1111,12 @@ func CreateBookingHandler(w http.ResponseWriter, r *http.Request) { http.Error(w, "You already have an active booking.
