几天来，我一直在努力在 Django 中设置视图/网址。努力让我的头脑围绕它每个人似乎都略有不同。
我想要实现的是：
我想有一个博客，我可以在该网站上发布新闻帖子，该网站将位于示例 - mysite.com/blog/ 然后您可以点击查看单独的帖子，它会从每个帖子中拉出蛞蝓。（这非常有效）。
但是我想从博客应用程序中提取帖子，以便主页。因此，您可以查看最新帖子的片段。我现在明白我需要在 app 文件夹之外和主目录中创建一个视图和一个 URL。但是我正在努力让他们联系在一起。我目前收到上面显示的错误消息。“没有博客与给定的查询匹配。” 这是我的 URL、模型和 2 个不同视图文件夹的代码。
//URLS for app and main directory

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

admin.autodiscover()
authority.autodiscover()
urlpatterns = patterns('',
url(r'^admin/doc/', include('django.contrib.admindocs.urls')),
(r'^authority/', include('authority.urls')),
(r'^i18n/', include('django.conf.urls.i18n')),
(r'^admin/', include(admin.site.urls)),
url(r'^$', 'views.blog', name='index'),
url(r'^blog/(?P<slug>[-\w]+)/$', 'blog.views.blog', name="blog"),
url(r'^blog/$', 'blog.views.blog_index', name="blog_index"),
)
if settings.DEBUG:
urlpatterns += patterns('',
# Trick for Django to support static files (security hole: only for Dev environement! remove this on Prod!!!)
