Question

过去几天我一直在努力学习Django，但最近我偶然发现了一个似乎无法修复的问题。在完成Django自己编写第一个应用程序的教程后，我决定再次完成它。只有现在我才会更换所有内容以满足我正在构建的原始应用程序的要求。

所以，一切顺利，直到我第3部分。当我尝试加载http://localhost:8000/lru/时，我收到以下错误消息：

AttributeError at /lru/
'module' object has no attribute 'index'

    url(r'^$', views.index, name='index')
AttributeError: 'module' object has no attribute 'index'

我的代码：

views.py

from django.http import HttpResponse

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

LRU / urls.py

from django.conf.urls import patterns, url

from lru import views

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

的mysite / urls.py

from django.conf.urls import patterns, include, url

from django.contrib import admin
admin.autodiscover()

urlpatterns = patterns('',
    url(r'^polls/', include('polls.urls', namespace="polls")),
    url(r'^admin/', include(admin.site.urls)),
    url(r'^lru/', include('lru.urls', namespace="lru")),
)

我的文件夹结构如下所示：

mysite/
    lru
    templates
    polls
    manage.py
    mysite

lru/
    templates
    urls.py
    admin.py
    __init__.py
    models.py
    tests.py
    views.py

这很奇怪，因为我完成了所有事情，就像我在“民意调查”中所做的那样。只需更换名称。当我在mysite / urls.py中注释url(r'^lru/', include('lru.urls', namespace="lru")),时，http://localhost:8000/polls/工作正常，但我似乎无法使用/ lru工作。

这真的让我感到害怕，所以任何形式的帮助都会受到赞赏！

编辑：添加了完整的追溯

Answer 1

要么这样做：

from lru.views import *

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

或

from lru import views

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

我希望这会有所帮助。

Answer 2

将urls.py模块导入视图。像这样;

from django.http import HttpResponse
from . import urls

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

Answer 3

url()的第二个参数应该是字符串，然后我会将lru/urls.py更改为：

from django.conf.urls import patterns, url

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

希望它有所帮助！

Answer 4

我刚刚发现 Sublime 文本正在混合......和制表符来缩进，我猜这取决于复制/粘贴源。

Django：'module'对象没有属性'index'
