Django - 导入错误：没有名为 *.urls 的模块

Question

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

我正处于它让我映射 URL 的地步，但是当很明显有一个模块包含一个恰当命名的文件时，我不断收到“没有名为 customers.urls 的模块”错误，所以我真的很茫然至于我做错了什么。

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

ROOT_URLCONF = 'taco.urls'（taco 是项目的名称）

我正在使用 manage.py/runserver 运行它，因此我知道没有特殊的 Web 服务器欺骗发生。我已经重启了好几次了。

这些应用程序都已正确注册，正如回溯可以证明的那样。

任何关于我忽略的东西的指针都将不胜感激！

根/urls.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/urls.py：

from django.conf.urls import patterns, url;

from customers import views;

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

客户/views.py：

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

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

Answer 1

在您的客户/urls.py 中：

改变这个：

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

为此：

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

另外，请确保您的 __init__.py 文件包含在包 customers 中。并且 INSTALLED_APPS 正确填写了您的应用名称。

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',
)

Answer 2

如果 taco 是项目的名称，请检查应用是否被正确引用，因此在您安装的应用中，您可能需要以下内容：

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')
