Issue #4: Pagination logic was repeated across multiple routes.
Changes:
- Add pagination.py with reusable utilities:
- calculate_total_pages: computes page count from total/per_page
- calculate_offset: computes offset for given page
- create_paginated_response: builds PaginatedResponse with metadata
- Update routes/audit.py to use pagination utilities
- Update routes/booking.py to use pagination utilities
- Update routes/invites.py to use pagination utilities
The utilities handle the common pagination math while routes
still manage their own query logic (filters, joins, ordering).
- Add ruff as dev dependency
- Configure ruff in pyproject.toml with strict 88-char line limit
- Ignore B008 (FastAPI Depends pattern is standard)
- Allow longer lines in tests for readability
- Fix all lint issues in source files
- Add Makefile targets: lint-backend, format-backend, fix-backend
- Added specific slot time and date to availability error message
- Added appointment ID and context to 'not found' errors
- Added formatted appointment time to past appointment cancellation errors
- Added date context to slot overlap error messages
- All errors now provide actionable information to users
- Added explicit joinedload(Appointment.user) to admin appointment queries
- Makes the eager loading intention clear and explicit
- Replaced comment-based documentation with actual query options
- Created _get_valid_minute_boundaries() helper that derives valid minutes from SLOT_DURATION_MINUTES
- Replaced hardcoded (0, 15, 30, 45) with dynamic calculation
- Error message now includes valid minute values for better clarity
- Created _to_appointment_response() helper function
- Replaced 5 duplicate AppointmentResponse constructions with helper calls
- Helper handles both explicit user_email and eager-loaded user relationship cases
- Added pagination with page/per_page query params
- Fixed N+1 query by using eager-loaded user relationship
- Removed unused _get_user_email helper function
- Updated frontend to handle paginated response
- Regenerated API types
Created shared_constants.py module that loads constants from the
shared JSON file. Updated availability.py and booking.py to import
from this module instead of hardcoding values.
This ensures backend and frontend stay in sync with the same source
of truth for booking configuration.
Add check to both user and admin cancel endpoints to reject
cancellation of appointments whose slot_start is in the past.
This matches the spec requirement that cancellations can only
happen 'before the appointment'.
Added tests for both user and admin cancel endpoints.
Also includes frontend styling updates.
