Страница не найдена (404) Метод запроса: GET URL запроса: http://127.0.0.1:8000/hello

Question

Django версия = 1.11
Версия Python = 3.6.5
Калани - папка проекта
testapp - это папка приложения

Я думаю, что моя проблема в urls.py.

http://127.0.0.1:8000/hello

Сообщение об ошибке:

 ERROR:

 Page not found (404)
 Request Method:    GET
 Request URL:   http://127.0.0.1:8000/hello
 Using the URLconf defined in kalani.urls, Django tried these URL 
 patterns, in this order:

^admin/
The current path, hello, didn't match any of these.

You're seeing this error because you have DEBUG = True in your Django 
settings file. Change that to False, and Django will display a standard 
404 page

TestApp / views.py:

from django.shortcuts import render
from django.http import HttpResponse
# Create your views here.
def hello(request):
   return HttpResponse('<h1>Hello world</h1>')

Kalani / urls.py:

 from django.conf.urls import url
 from django.contrib import admin
 from testapp import views

 urlpatterns = [
     url(r'^admin/', admin.site.urls),
     url(r'^hello/', views.hello)
 ]

Kalani / settings.py

INSTALLED_APPS = [
   'django.contrib.admin',
   'django.contrib.auth',
   'django.contrib.contenttypes',
   'django.contrib.sessions',
   'django.contrib.messages',
   'django.contrib.staticfiles',
   'testapp'
]

Answer 1

Вы должны импортировать эти URL в переменную ROOT_URLCONF под вашим settings.py, например:

...
ROOT_URLCONF = 'kalani.urls'
...
