Transport System Detailed Workflow

Based on the transport views and templates, here's the complete workflow for your Django travel application:

🏠 1. Transport Home Page (/transport/)

View: transport_home

def transport_home(request):

    context = {

        'airport_count': Airport.objects.filter(is_active=True).count(),

        'airline_count': Airline.objects.filter(is_active=True).count(),

        'station_count': TransportStation.objects.filter(is_active=True).count(),

        'city_count': City.objects.count(),

    }

    return render(request, 'transport/transport_home.html', context)

Workflow:

1. User visits /transport/
2. System counts active airports, airlines, stations, and cities
3. Displays dashboard with transport statistics and navigation options
4. User chooses between Flight Search or Transit Search

✈️ 2. Flight Search Workflow (/transport/flights/)

Step 1: Initial Page Load

def flight_search(request):

    airports = Airport.objects.filter(is_active=True).select_related('city', 'city__country')

    flights = None

Step 2: User Input & Search

1. User selects:
   • Origin airport (IATA code)
   • Destination airport (IATA code)
   • Departure date (optional)
2. Form submission triggers GET request with parameters:
   • ?origin=SGN&destination=HAN&departure_date=2024-08-20

Step 3: Backend Processing

if request.GET.get('origin') and request.GET.get('destination'):

    origin_code = request.GET.get('origin')

    destination_code = request.GET.get('destination')

    departure_date = request.GET.get('departure_date')

    flights_qs = Flight.objects.filter(

        origin_airport__iata_code=origin_code,

        destination_airport__iata_code=destination_code,

        status__in=['SCHEDULED', 'DELAYED']

    ).select_related(...)

Step 4: Results Display

• Shows matching flights with airline, aircraft, times, prices
• Limited to 20 results for performance
• Each flight has "View Details" link

Step 5: Flight Detail (/transport/flights/{id}/)

def flight_detail(request, flight_id):

    flight = get_object_or_404(Flight.objects.select_related(...), pk=flight_id)

🚌 3. Transit Search Workflow (/transport/transit/)

Step 1: Page Load with Route Mapping

def transit_search(request):

    stations = TransportStation.objects.filter(is_active=True).select_related('city')

    # Build route mapping for JavaScript

    available_routes = {}

    all_transits = Transit.objects.select_related('origin_station', 'destination_station')

    for transit in all_transits:

        origin_id = transit.origin_station_id

        if origin_id not in available_routes:

            available_routes[origin_id] = set()

        available_routes[origin_id].add(transit.destination_station_id)

    route_data_json = json.dumps({str(k): list(v) for k, v in available_routes.items()})

Step 2: Frontend Filtering (JavaScript)

1. Transit Type Selection:
   • User clicks Bus/Train/Ferry/Metro tab
   • JavaScript filters stations by type

1. • document.querySelectorAll('[data-transit-type]').forEach(tab => {
   •     tab.addEventListener('click', function() {
   •         const transitType = this.dataset.transitType;
   •         filterStations(transitType);
   •     });
   • });Origin Station Selection:
   • JavaScript uses route_data to filter destination options
   • Only shows reachable destinations
2.  

Step 3: Search Execution

• if request.GET.get('origin_station') and request.GET.get('destination_station'):
•     origin_id = request.GET.get('origin_station')
•     destination_id = request.GET.get('destination_station')
•     departure_date = request.GET.get('departure_date')
•     transit_type = request.GET.get('transit_type')
•    
•     transits_qs = Transit.objects.filter(
•         origin_station_id=origin_id,
•         destination_station_id=destination_id,
•     ).select_related('operator', 'origin_station__city', 'destination_station__city')Step 4: Results & Detail

• Displays matching transit options
• Links to transit detail page (/transport/transit/{id}/)

📊 4. Legacy Views Workflow

Flight List (/transport/flights/list/)

def flight_list(request):

    flights_qs = Flight.objects.select_related(...).order_by('-departure_time')

    # Statistics calculation

    scheduled_count = flights_qs.filter(status='SCHEDULED').count()

    delayed_count = flights_qs.filter(status='DELAYED').count()

    flights = flights_qs[:50]  # Recent 50 flights

Transit List (/transport/transits/)

def transit_list(request):

    transits_qs = Transit.objects.select_related(...).order_by('-departure_time')

    # Statistics by type

    train_count = transits_qs.filter(type='TRAIN').count()

    bus_count = transits_qs.filter(type='BUS').count()

    # ... other types

    transits = transits_qs[:50]  # Recent 50 transits
