找不到带有参数'（''，''）'的'ptrips'反向。尝试了1个模式：['details / trips /（？P <trip_id> [0-9] +）/（？P <passenger_id> [0-9] +）/ $']

Question

这是一个火车票预订系统，我试图在同一URL路径上传递2个id（trip_id / passenger_id），以便django可以记住乘客人数，然后根据乘客人数创建许多门票表格通过ID

urls.py

    path('trips/<int:trip_id>/',views.ticket_booking, name='trips'),
    path('trips/<int:trip_id>/<int:passenger_id>/',views.passengers_page, name='ptrips'),
    path('review/<int:ticket_id>/',views.review_page, name='rtickets'),
    re_path(r'^from/(?P<start_station>[0-9]{1,50})/$', views.details_page, name='details_page'),
    path('', views.details_page, name='booking'),

views.py

from django.shortcuts import render, redirect
from django.http import HttpResponse
from django.core.exceptions import ValidationError
from .models import Ticket, Trip, Passenger
from django.http import Http404
from django.shortcuts import get_object_or_404

def ticket_booking(request, trip_id, passenger_id):
    trip = get_object_or_404( Trip, pk=trip_id)
    passengers = list(Passenger.objects.filter(pk=passenger_id))
    error = None
    ticket = None
    if request.method == 'POST':
        first_name = request.POST.get('first_name')
        middle_name = request.POST.get('middle_name')
        last_name = request.POST.get('last_name')
        email = request.POST.get('email')
        gender = request.POST.get('gender')
        ticket = Ticket(trip=trip,first_name=first_name, middle_name=middle_name,
            last_name=last_name, email=email,gender=gender)
        try:
            ticket.full_clean()
            ticket.save()
            return redirect('tickets',ticket_id=ticket.id)
        except ValidationError as e:
            error = dict(e)
            print(e)
    context = { 'trip': trip,'error':error, 'ticket':ticket, 'passengers':passengers }
    return render(request, 'details/ticket.html', context)
