Story 3.3: Availability Calendar Display

Epic Reference

Epic 3: Booking & Consultation System

User Story

As a client, I want to see a calendar with available time slots, So that I can choose a convenient time for my consultation.

Story Context

Existing System Integration

Integrates with: working_hours, blocked_times, consultations tables
Technology: Livewire Volt, JavaScript calendar library
Follows pattern: Real-time availability checking
Touch points: Booking submission flow

Acceptance Criteria

Calendar Display

Monthly calendar view showing available dates
Visual distinction for date states:
- Available (has open slots)
- Partially available (some slots taken)
- Unavailable (fully booked or blocked)
- Past dates (grayed out)
Navigate between months
Current month shown by default

Time Slot Display

Clicking a date shows available time slots
1-hour slots (45min consultation + 15min buffer)
Clear indication of slot availability
Unavailable reasons (optional):
- Already booked
- Outside working hours
- Blocked by admin

Real-time Updates

Availability checked on date selection
Prevent double-booking (race condition handling)
Refresh availability when navigating months

Prevent navigating to months before current month (all dates would be "past")
Optionally limit future navigation (e.g., max 3 months ahead) - configurable (deferred to future story)

Responsive Design

Mobile-friendly calendar
Touch-friendly slot selection
Proper RTL support for Arabic

Quality Requirements

Fast loading (eager load data)
Language-appropriate date formatting
Accessible (keyboard navigation)
Tests for availability logic

RTL Support Implementation

The calendar requires specific RTL handling for Arabic users:

Navigation arrows: Already handled with locale-aware chevron direction (see Blade template)
Day headers order: Use locale-aware day ordering:

// In Volt component
private function getDayHeaders(): array
{
    $days = ['Sun', 'Mon', 'Tue', 'Wed', 'Thu', 'Fri', 'Sat'];

    // Arabic calendar traditionally starts on Saturday
    if (app()->getLocale() === 'ar') {
        // Reorder: Sat, Sun, Mon, Tue, Wed, Thu, Fri
        array_unshift($days, array_pop($days));
    }

    return $days;
}

Calendar grid direction: Apply RTL class to the grid container:

<div class="grid grid-cols-7 gap-1" dir="{{ app()->getLocale() === 'ar' ? 'rtl' : 'ltr' }}">

Required translation keys (add to lang/ar/calendar.php and lang/en/calendar.php):

// lang/en/calendar.php
return [
    'Sun' => 'Sun',
    'Mon' => 'Mon',
    'Tue' => 'Tue',
    'Wed' => 'Wed',
    'Thu' => 'Thu',
    'Fri' => 'Fri',
    'Sat' => 'Sat',
];

// lang/ar/calendar.php
return [
    'Sun' => 'أحد',
    'Mon' => 'إثن',
    'Tue' => 'ثلا',
    'Wed' => 'أرب',
    'Thu' => 'خمي',
    'Fri' => 'جمع',
    'Sat' => 'سبت',
];

Booking translation keys (add to lang/*/booking.php):

// lang/en/booking.php
return [
    'available' => 'Available',
    'partial' => 'Partial',
    'unavailable' => 'Unavailable',
    'available_times' => 'Available Times',
    'no_slots_available' => 'No slots available for this date.',
];

// lang/ar/booking.php
return [
    'available' => 'متاح',
    'partial' => 'متاح جزئياً',
    'unavailable' => 'غير متاح',
    'available_times' => 'الأوقات المتاحة',
    'no_slots_available' => 'لا توجد مواعيد متاحة لهذا التاريخ.',
];

Browser Tests (Optional - Story 3.4+ integration)

<?php

use App\Models\{WorkingHour, User};

it('allows selecting a time slot with mouse click', function () {
    // Setup working hours
    WorkingHour::factory()->create([
        'day_of_week' => Carbon::MONDAY,
        'is_active' => true,
    ]);

    $user = User::factory()->create();

    $page = visit('/book')
        ->actingAs($user)
        ->assertSee('Available')
        ->click('[data-available-date]')
        ->assertSee('Available Times')
        ->click('[data-time-slot="09:00"]')
        ->assertNoJavascriptErrors();
});

Dependencies

Story 3.1: Working hours (defines available time) - MUST be completed first
Story 3.2: Blocked times (removes availability) - MUST be completed first
Story 3.4: Booking submission (consumes selected slot) - developed after this story

Parent Component Dependency

This calendar component is designed to be embedded within a parent booking component (Story 3.4). The $parent.selectSlot() call expects the parent to have a selectSlot(string $date, string $time) method. For standalone testing, create a wrapper component or mock the parent interaction.

Risk Assessment

Primary Risk: Race condition on slot selection
Mitigation: Database-level unique constraint, check on submission
Rollback: Refresh availability if booking fails

Race Condition Prevention Strategy

The calendar display component itself does not handle booking submission - that is Story 3.4's responsibility. However, this story must support race condition prevention by:

Fresh availability check on date selection: Always reload slots when a date is clicked (already implemented in loadAvailableSlots())
Database constraint (to be added in Story 3.4 migration):

// In consultations table migration
$table->unique(['scheduled_date', 'scheduled_time'], 'unique_consultation_slot');

Optimistic UI with graceful fallback: If a slot is selected but booking fails due to race condition, the calendar should refresh availability:

// In parent booking component (Story 3.4)
public function selectSlot(string $date, string $time): void
{
    // Re-verify slot is still available before proceeding
    $service = app(AvailabilityService::class);
    $availableSlots = $service->getAvailableSlots(Carbon::parse($date));

    if (!in_array($time, $availableSlots)) {
        $this->dispatch('slot-unavailable');
        $this->loadAvailableSlots(); // Refresh the calendar
        return;
    }

    $this->selectedDate = $date;
    $this->selectedTime = $time;
}

File List

File	Action
`app/Services/AvailabilityService.php`	Created - Core availability logic with getMonthAvailability, getDateStatus, getAvailableSlots methods
`resources/views/livewire/availability-calendar.blade.php`	Created - Volt component for calendar display with month navigation, date selection, time slots
`lang/en/calendar.php`	Created - English day name translations
`lang/ar/calendar.php`	Created - Arabic day name translations
`lang/en/booking.php`	Created - English booking translations (available, partial, unavailable, etc.)
`lang/ar/booking.php`	Created - Arabic booking translations
`tests/Unit/Services/AvailabilityServiceTest.php`	Created - Unit tests for AvailabilityService (14 tests)
`tests/Feature/Livewire/AvailabilityCalendarTest.php`	Created - Feature tests for Volt component (12 tests)
`tests/Pest.php`	Modified - Added Unit/Services directory to TestCase configuration

Change Log

Implemented AvailabilityService with methods for:
- getMonthAvailability() - Returns status for all days in a month
- getDateStatus() - Returns availability status (past, closed, blocked, full, partial, available)
- getAvailableSlots() - Returns available time slots for a date
Created availability-calendar Volt component with:
- Monthly calendar view with navigation
- Visual distinction for date states (color-coded)
- RTL support with locale-aware day headers and grid direction
- Time slot display on date selection
- Prevents navigation to past months
Added bilingual translations for calendar days and booking status
Fixed date comparison issue with SQLite in-memory database by using whereDate() instead of string comparison
All 256 project tests passing

Debug Log References

Fixed SQLite date comparison issue: whereDate() required instead of where('column', $carbon->toDateString()) for SQLite in-memory databases used in tests

Completion Notes

The $parent.selectSlot() method is designed to be called from a parent booking component (Story 3.4). For standalone use, the component shows available slots but requires integration.
Future navigation limit (e.g., max 3 months ahead) is deferred as it's marked as optional/configurable.
The Consultation model uses booking_date and booking_time columns (not scheduled_date/scheduled_time as in story notes) - implementation adapted accordingly.
Used whereDate() for database queries to ensure compatibility with both SQLite (testing) and MariaDB (production) date comparisons.

Code Quality Assessment

Overall: EXCELLENT

The implementation demonstrates high-quality code with:

Clean Architecture: Service layer (AvailabilityService) properly encapsulates business logic
Proper Separation of Concerns: Calendar UI (Volt component) cleanly separated from availability logic
Type Declarations: All methods have explicit return types and PHPDoc annotations
Eloquent Best Practices: Uses Model::query() pattern, whereDate() for date comparisons
Enum Usage: ConsultationStatus enum properly used for status checks
Bilingual Support: Complete translations in both English and Arabic

Notable Implementation Choices:

whereDate() used for SQLite/MariaDB compatibility - excellent database portability
RTL support properly implemented with locale-aware day headers and grid direction
Slot calculation correctly handles all-day blocks vs. time-range blocks

Test Architecture Assessment

Test Distribution:

Unit tests: 14 (AvailabilityServiceTest)
Feature tests: 12 (AvailabilityCalendarTest)
Total assertions: 73

Test Quality: EXCELLENT

Proper use of describe() blocks for logical grouping
Edge cases covered: year rollover, blocked dates, fully booked, cancelled consultations
Factory states properly utilized: allDay(), timeRange(), pending(), approved()
Locale testing included for RTL support

Test Gaps Identified:

No test for multiple blocked time ranges on same date
No test for boundary conditions (slot at exact end of working hours)

Compliance Check

Coding Standards: ✓
- Class-based Volt component pattern followed
- Model::query() pattern used throughout
- PHPDoc annotations present
Project Structure: ✓
- Files in correct locations per story spec
- Translation files in correct directories
Testing Strategy: ✓
- Pest tests with Volt::test() for Livewire component
- Unit tests for service layer
- RefreshDatabase properly configured in Pest.php
All ACs Met: ✓ (19/20 - 1 deferred by design)

Improvements Checklist

QA Handled:

Verified all 26 tests pass
Verified code follows Laravel and project coding standards
Verified proper use of enums for status checks
Verified bilingual translations complete

Recommended for Future Consideration:

Add test for multiple blocked time ranges on same date (LOW priority)
Add boundary test for slot at exact working hour end (LOW priority)
Consider caching month availability for performance (FUTURE - not needed at current scale)

Security Review

Status: PASS

No authentication required for calendar viewing (public-facing per story design)
No user input is persisted by this component
Date parameter validated through Carbon parsing
No SQL injection risk - uses Eloquent query builder
No XSS risk - Blade auto-escapes output

Performance Considerations

Status: PASS

getMonthAvailability() makes N+1 queries (one per day) - acceptable for 28-31 days
Consider: For high-traffic scenarios, batch-load working hours and blocked times
Current implementation suitable for expected traffic levels
