django - Django NoReverseMatch

问题描述

我正在尝试将 API 用作我正在从事的项目的一部分，但目前遇到了一些困难：

API https://developers.amadeus.com/self-service/category/air/api-doc/airport-and-city-search

API - Python SDK https://github.com/amadeus4dev/amadeus-python

Django API 指南 https://developers.amadeus.com/blog/django-jquery-ajax-airport-search-autocomplete

我已按照上述指南中的说明进行操作；但是，我在尝试呈现包含代码的索引页面时收到以下错误：

Reverse for 'origin_airport_search' not found. 'origin_airport_search' is not a valid view function or pattern name.

索引模板：

主要 - urls.py：

"""finalproject URL Configuration

The `urlpatterns` list routes URLs to views. For more information please see:
    https://docs.djangoproject.com/en/3.1/topics/http/urls/
Examples:
Function views
    1. Add an import:  from my_app import views
    2. Add a URL to urlpatterns:  path('', views.home, name='home')
Class-based views
    1. Add an import:  from other_app.views import Home
    2. Add a URL to urlpatterns:  path('', Home.as_view(), name='home')
Including another URLconf
    1. Import the include() function: from django.urls import include, path
    2. Add a URL to urlpatterns:  path('blog/', include('blog.urls'))
"""
from django.contrib import admin
from django.urls import include, path

urlpatterns = [
    path('', include('flightfinder.urls', namespace='Flightfinder')),
    path('admin/', admin.site.urls),
]

应用程序 - urls.py：

from django.urls import path

from . import views

app_name = 'flightfinder'

urlpatterns = [
    path('', views.index, name='index'),
    path('origin_airport_search/', views.origin_airport_search, name='origin_airport_search')
]

视图.py：

import json
from django.shortcuts import render
from django.http import HttpResponse
from django.contrib import messages
from amadeus import Client, ResponseError, Location

from .models import Airport, Flight, Passenger

amadeus = Client(client_id='removed', 
                 client_secret='removed', 
                 log_level='debug') 

# Create your views here.
def index(request):
    return render(request, 'flightfinder/index.html')

def origin_airport_search(request):
    if request.is_ajax():
        try:
            data = amadeus.reference_data.locations.get(keyword=request.GET.get('term', None), subType=Location.ANY).data
        except ResponseError as error:
            messages.add_message(request, messages.ERROR, error)
    return HttpResponse(get_city_airport_list(data), 'application/json')

def get_city_airport_list(data):
    result = []
    for i, val in enumerate(data):
        result.append(data[i]['iataCode']+', '+data[i]['name'])
    result = list(dict.fromkeys(result))
    return json.dumps(result)

我查看了一些类似的堆栈查询，但到目前为止它们都没有帮助。如果有人有任何想法可以在这里尝试，将不胜感激？

谢谢！
