python - Django "No Module Named URLs"错误

Question

已经有很多类似的问题发布了，但我已经尝试过这些解决方案，但都无济于事。我正在完成基本的 Django 教程，这是我的代码:

网址.py

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

from django.contrib import admin
admin.autodiscover()

urlpatterns = patterns('',
    # Examples:
    # url(r'^$', 'tango_with_django_project.views.home', name='home'),
    # url(r'^tango_with_django_project/', include('tango_with_django_project.foo.urls')),

    # Uncomment the admin/doc line below to enable admin documentation:
    url(r'^admin/doc/', include('django.contrib.admindocs.urls')),

    # Uncomment the next line to enable the admin:
    url(r'^admin/', include(admin.site.urls)),

    url(r'^rango/', include('rango.urls')), # ADD THIS NEW TUPLE!
)

View .py

from django.http import HttpResponse

def index(request):
    return HttpResponse("Rango says hello world!")

来自settings.py文件

ROOT_URLCONF = 'tango_with_django_project.urls'

希望大家能帮助我入门

假设我有一个名为 FailBook 的 Django 项目，其中包含两个应用程序、帖子和链接。如果我查看 FailBook/urls.py，我会发现类似

的内容

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

from django.contrib import admin
admin.autodiscover()

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

    url(r'^posts/', include('posts.urls')), ## Custom url include
    url(r'^links/', include('links.urls')), ## Custom url include
)

那么，当你查看目录结构时，你会发现多了两个 urls.py 文件

FailBook
|-- posts
   |-- models.py
   |-- urls.py
   |-- views.py
   |-- etc.
|-- links
   |-- models.py
   |-- urls.py
   |-- views.py
   |-- etc.

# urls.py file in the posts folder
from django.conf.urls import patterns, include, url
from .views import PostListView, PostDetailView

urlpatterns = patterns('',

    url(r'^posts/', PostListView.as_view()), 
    url(r'^posts/(?P<post_id>\d+)', PostDetailView.as_view()),
)
# where both views are class based views, hence the as_view function call
