mysite的/ mysite的/ urls.py：

from django.conf.urls import include, url
from django.contrib import admin

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

mysite的/轮询/ urls.py：

from django.conf.urls import url

from . import views

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

mysite的/轮询/ views.py：

# -*- coding: utf-8 -*-
from __future__ import unicode_literals

from django.shortcuts import render

from django.http import HttpResponse

def index(request):
    return HttpResponse("Hello, world, You're at the polls index.")

# Create your views here.

文件层次结构：

mysite

- manage.py

- mysite
--- __init__.py
--- settings.py
--- urls.py
--- wsgi.py

- polls
--- __init__.py
--- admin.py
--- apps.py
--- migrations
----- __init__.py
--- models.py
--- tests.py
--- urls.py
--- views.py

错误令我感到困惑，因为我的文件是官方教程的COPIES。我已经看到其他人有这个问题，但为他们提供的解决方案似乎并没有解决我的问题，例如将url(r'^$', views.index, name='index'),更改为url(r'^$', 'views.index', name='index'),只会导致另一个错误（第二个参数不应该是字符串）。

Answer 1

试试这个：

from django.conf.urls import url

from polls.views import index

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

我希望您在自己的设置中包含民意调查：

INSTALLED_APPS = [
    # ... default values
    'polls',
]

Answer 2

您需要将其更改为：

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

这告诉Django查看'views'文件以及名为'index'的视图
