django 1.8 tutorial часть 3

Question

Я пытаюсь выполнить учебник django 1.8, я нахожусь на части 3, и получаю ошибку Exception Value: 'module' object has no attribute 'index'. Похоже, что он неправильно импортирует views.py. Любая помощь? Благодаря!

Вот мой urls.py:

from django.conf.urls import patterns, url 
from polls import views 

urlpatterns = patterns('', 
    url(r'^$', views.index, name='index'), 
) 

Вот мой views.py:

from django.shortcuts import render 
from django.http import HttpResponse 

# Create your views here. 
def index(request): 
    return HttpResponse("Hello, World. You're at the polls index") 

Вот моя ошибка выхода:

Answer 1

Это ошибка импорта, попробуйте:

from polls.views import index 

И в URL:

url(r'^$', index, name='index'), 

EDIT

не только для руководства:

Если urls.py и views.py находятся на том же уровне, использование:

from . import views 

И в URL:

url(r'^$', views.index, name='index'), 

Answer 2

Если вы внимательно следит за учебным курсом см. в разделе urls.py,

from poll import views 

фактически

from . import views 

Answer 3

Try:

from . import views # relative import 

Фактический код в tutorial является:

from django.conf.urls import url 

from . import views 

urlpatterns = [ 
    url(r'^$', views.index, name='index'), 
] 

Кроме того, в Django 1.8 urlpatterns должен быть список django.conf.urls.url() экземпляров.

По Django 1.8 docs:

urlpatterns должен быть список Python из django.conf.urls.url() экземпляров.

В Django 1.7, urlpatterns переменная используется как список Python, в формате, возвращаемом функцией django.conf.urls.patterns().
