Django：'module'对象没有属性'index'

问题描述

过去几天我一直在尝试学习Django，但最近我偶然发现了一个我似乎无法解决的问题。在完成Django自己的教程第一个应用程序之后，我决定再次通过它。只有现在我将替​​换所有的东西，以适应我正在建立的原始应用程序的要求。

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

  / lru / 
'module'对象的AttributeError没有属性'index'

来自django.conf.urls导入模式的

 ，来自lru导入视图的url 
 
 
 
 urlpatterns = patterns（''，
 url（r'^ $'，views.index，name ='index'）
）
  

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）），
 ur l（r'^ lru /'，include（'lru.urls'，namespace =lru）），
）
  

我的文件夹结构如下所示：

  mysite / 
 lru 
模板
民意调查
 manage.py 
 mysite 
 
 lru / 
模板
 urls.py 
 admin.py 
 __init__.py 
 models.py 
 tests.py 
 views.py 
  

这很奇怪，因为我已经完成了一切，就像我在民意测验例子中所做的一样。只是替换名字。当我在mysite / urls.py中注释出 url（r'^ lru /'，include（'lru.urls'，namespace =lru））， http：// localhost：8000 / polls / 工作正常，但我似乎无法让/ lru上班。

这真的是杀了我，所以任何形式的帮助将是感激的！

编辑：添加完全追踪

解决方案

可以这样做：

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

或

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

我希望这有帮助。

I've been trying to learn Django for the past few days, but recently I've stumbled upon a problem I can't seem to fix. After finishing Django's own tutorial on writing your first app I decided to go through it again. Only now I would replace everything to fit the requirements of the original app I was building.

So, everything went well until I got to part 3. When I try to load http://localhost:8000/lru/ I get the following error message:

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

Traceback:

Internal Server Error: /favicon.ico

AttributeError: 'module' object has no attribute 'index'

My code:

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')
)

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")),
)

My folder structure looks like this:

mysite/
    lru
    templates
    polls
    manage.py
    mysite

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

It's strange because I've done everything exactly as I did in the "polls" example turtorial. Just replacing the names. When I comment out url(r'^lru/', include('lru.urls', namespace="lru")), in mysite/urls.py, then http://localhost:8000/polls/ works fine, but I just can't seem to get /lru to work.

This is really killing me so any form of help would be appreciative!

Edit: Added full traceback

解决方案

Either do this :

from lru.views import *

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

or

from lru import views

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

I hope this helps.
