Story 3.4: Booking Request Submission

Status

Ready for Review

Epic Reference

Epic 3: Booking & Consultation System

Story

As a client, I want to submit a consultation booking request, so that I can schedule a meeting with the lawyer.

Acceptance Criteria

Booking Form (AC1-5)

  1. Client must be logged in
  2. Select date from availability calendar
  3. Select available time slot
  4. Problem summary field (required, textarea, min 20 characters)
  5. Confirmation before submission

Validation & Constraints (AC6-9)

  1. Validate: no more than 1 booking per day for this client
  2. Validate: selected slot is still available
  3. Validate: problem summary is not empty
  4. Show clear error messages for violations

Submission Flow (AC10-14)

  1. Booking enters "pending" status
  2. Client sees "Pending Review" confirmation
  3. Admin receives email notification
  4. Client receives submission confirmation email
  5. Redirect to consultations list after submission

UI/UX (AC15-18)

  1. Clear step-by-step flow
  2. Loading state during submission
  3. Success message with next steps
  4. Bilingual labels and messages

Quality Requirements (AC19-22)

  1. Prevent double-booking (race condition)
  2. Audit log entry for booking creation
  3. Tests for submission flow
  4. Tests for validation rules

Calendar Integration Note

The availability-calendar component (from Story 3.3) uses the pattern $parent.selectSlot() to communicate slot selection back to the parent component. The parent booking component needs to have the selectSlot(string $date, string $time) method to receive this.

1-Per-Day Validation Rule

<?php
// app/Rules/OneBookingPerDay.php

namespace App\Rules;

use App\Enums\ConsultationStatus;
use App\Models\Consultation;
use Closure;
use Illuminate\Contracts\Validation\ValidationRule;

class OneBookingPerDay implements ValidationRule

Files to Create

File Purpose
resources/views/livewire/client/consultations/book.blade.php Main Volt component for booking submission
app/Rules/OneBookingPerDay.php Custom validation rule for 1-per-day limit
app/Mail/BookingSubmittedMail.php Email to client on submission
app/Mail/NewBookingRequestMail.php Email to admin for new booking
tests/Feature/Client/BookingSubmissionTest.php Feature tests for booking flow

Mail Classes

Create mail classes using artisan:

php artisan make:mail BookingSubmittedMail
php artisan make:mail NewBookingRequestMail

Both mail classes should:

  • Accept Consultation $consultation in constructor
  • Use bilingual subjects based on recipient's preferred_language
  • Create corresponding email views in resources/views/emails/

Translation Keys Required

Add to lang/en/booking.php:

'request_consultation' => 'Request Consultation',
'select_date_time' => 'Select a date and time for your consultation',
'selected_time' => 'Selected Time',
'problem_summary' => 'Problem Summary',
'problem_summary_placeholder' => 'Please describe your legal issue or question in detail...',
'problem_summary_help' => 'Minimum 20 characters. This helps the lawyer prepare for your consultation.',
'continue' => 'Continue',
'confirm_booking' => 'Confirm Your Booking',
'confirm_message' => 'Please review your booking details before submitting.',
'date' => 'Date',
'time' => 'Time',
'duration' => 'Duration',
'submit_request' => 'Submit Request',
'submitted_successfully' => 'Your booking request has been submitted. You will receive an email confirmation shortly.',
'already_booked_this_day' => 'You already have a booking on this day.',
'slot_no_longer_available' => 'This time slot is no longer available. Please select another.',
'slot_taken' => 'This slot was just booked. Please select another time.',

Add corresponding Arabic translations to lang/ar/booking.php.

Definition of Done

  • Admin email sent
  • Audit log entry created
  • Bilingual support complete
  • All tests passing
  • Code formatted with Pint

Dependencies

Risk Assessment

Risk Impact Mitigation
Double-booking race condition High DB transaction with lockForUpdate()
Email delivery failure Medium Use queue with retries
Timezone confusion Low Use whereDate() for date comparison

Change Log

Date Version Description Author
2025-12-26 1.0 Initial draft -

QA Results

Review Date: 2025-12-26

Reviewed By: Quinn (Test Architect)

Risk Assessment

Review Depth: Standard - No high-risk triggers detected (no auth/payment files modified beyond expected booking flow, reasonable test coverage, appropriate line count, first review).

Code Quality Assessment

Overall: Excellent - The implementation is clean, well-structured, and follows Laravel/Livewire best practices.

Strengths:

  • Clean Volt component architecture with proper separation of concerns
  • Excellent race condition prevention using DB::transaction() with lockForUpdate()
  • Double validation strategy (pre-confirmation + in-transaction) provides defense in depth
  • Proper use of Flux UI components throughout
  • Bilingual support complete with proper RTL handling in email templates
  • Good error handling with user-friendly messages

Code Patterns:

  • book.blade.php:76-134 - Transaction with pessimistic locking correctly prevents race conditions
  • book.blade.php:48-52,90-95 - 1-per-day validation checked both pre and in-transaction
  • Mail classes properly use Queueable trait and respect user's preferred_language

Test Architecture Assessment

Test Count: 18 tests, 50 assertions Test Level: Feature tests (appropriate for this user-facing workflow) Test Quality: High - tests cover happy path, validation, business rules, race conditions, and side effects

Coverage Analysis:

  • ✓ Happy path submission flow
  • ✓ Authentication guard
  • ✓ All validation rules (required, min, max)
  • ✓ Business rules (1-per-day, slot availability)
  • ✓ Race condition scenarios (slot taken, user double-book)
  • ✓ UI flow states (confirmation, back navigation, clear selection)
  • ✓ Side effects (emails queued, audit log created)

Test Design Quality:

  • Proper use of Mail::fake() for email assertions
  • Good isolation with beforeEach for working hours setup
  • Race condition tests simulate real concurrent booking scenarios
  • Tests verify both state changes and database records

Compliance Check

  • Coding Standards: ✓ Code formatted with Pint
  • Project Structure: ✓ Files in correct locations per architecture
  • Testing Strategy: ✓ Feature tests with Pest/Volt
  • All ACs Met: ✓ 22/22 acceptance criteria validated

Refactoring Performed

No refactoring performed - implementation is clean and follows best practices.

Improvements Checklist

  • Race condition prevention with DB locking
  • Double validation (pre + in-transaction)
  • Email queuing for async delivery
  • Proper loading states in UI
  • Full bilingual support
  • Audit logging for client actions
  • Consider adding a test for admin-only notification when no admin exists (edge case - currently silently skips)
  • Consider extracting the 1-per-day check to a query scope on Consultation model for reuse

Security Review

Status: PASS

  • ✓ Authentication required via route middleware (auth, active)
  • ✓ Authorization implicit (client can only book for themselves via auth()->id())
  • ✓ Input validation with Laravel validator
  • ✓ SQL injection prevented via Eloquent ORM
  • ✓ XSS prevented via Blade escaping
  • ✓ CSRF protection via Livewire
  • ✓ Race condition prevention via pessimistic locking
  • ✓ Problem summary has max length (2000 chars) preventing payload attacks

Performance Considerations

Status: PASS

  • ✓ Emails queued (not blocking request)
  • ✓ Database queries are indexed (user_id, booking_date, status)
  • ✓ No N+1 query issues in the booking flow
  • ✓ Reasonable transaction scope (creates one consultation, logs one entry)

Files Modified During Review

None - no modifications needed.

Gate Status
