Django-导入错误：没有名为*.url的模块

Question

我正在研究official Django tutorial，并使用Django版本1.6.1和Python 2.7.6稍微调整它以满足我自己的需要。

我正处在它让我映射url的时候，但是当很明显有一个模块内有一个恰当命名的文件时，我不断地得到“没有模块命名的customers.URLs”错误，所以我真的不知道自己做错了什么。

我最初的想法是，我需要在root/url.py中导入一些与客户相关的内容，但是每次导入的组合都会导致大致相同的错误，教程并没有说明要这样做。

根URLCONF='taco.urls'（taco是项目的名称）

我使用manage.py/runserver运行这个程序，所以我不知道有什么特殊的web服务器欺骗。我已经重新启动了好几次。

回溯可以证明，所有应用程序都已正确注册。

任何关于我所忽略的东西的提示都将不胜感激！

根/url.py：

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

admin.autodiscover()

urlpatterns = patterns('',
    url(r'^customers/', include('customers.urls')),
    url(r'^admin/', include(admin.site.urls)),
)

客户/url.py：

from django.conf.urls import patterns, url;

from customers import views;

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

客户/视图.py：

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

def index(request):
    return HttpResponse("Hello");

Answer 1

如果项目名称为taco，请检查是否正确引用了应用程序，以便在已安装的应用程序中可能需要以下内容：

Installed Applications:
('django.contrib.admin',
 'django.contrib.auth',
 'django.contrib.contenttypes',
 'django.contrib.sessions',
 'django.contrib.messages',
 'django.contrib.staticfiles',
 'south',
 'customers',
 'inventory',
 'lookups',
 'orders')

Answer 2

在customers/url.py中：

更改此：

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

为此：

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

另外，确保您的__init__.py文件位于包customers中。并且INSTALLED_APPS正确地填充了您的应用程序名。

INSTALLED_APPS = (
    'django.contrib.auth',
    'django.contrib.contenttypes',
    'django.contrib.sessions',
    'django.contrib.sites',
    'django.contrib.messages',
    'django.contrib.staticfiles',
    'django.contrib.admin',
    'south',
    'customers',
    'inventory',
    'lookups',
    'orders',
)
