Question

有时我想打开about页面，联系人，创建或博客页面出现此错误：引发：blog.views.blog_postDetailView 我不知道为什么，但我认为它必须与我的urlpattterns做或者他们的顺序。我的代码。感谢您的帮助和改进非常感谢

mainurl

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


from django.conf import settings
from django.conf.urls.static import static

from blog.views import AboutPageView, ContactPageView, blog_postCreateView

urlpatterns = [

    url(r'^about/', AboutPageView.as_view(), name='about'),
    url(r'^contact/', ContactPageView.as_view(), name='contact'),
    url(r'^create/', blog_postCreateView.as_view(), name='blog_post_create'),
    url(r'', include('blog.urls')),
    url(r'^blog/', include('blog.urls')),

   #admin and login
   url(r'^admin/', admin.site.urls), 
   url(r'^accounts/', include('registration.backends.default.urls')),

]


if settings.DEBUG:
    urlpatterns += static(settings.STATIC_URL, document_root=settings.STATIC_ROOT)
    urlpatterns += static(settings.MEDIA_URL, document_root=settings.MEDIA_ROOT)

博客网址

from django.conf.urls import url

from .views import blog_postListView, blog_postDetailView, blog_postCreateView 

urlpatterns = [

    url(r'^$', blog_postListView.as_view(), name='blog_post_list'),
    url(r'^(?P<slug>[-\w]+)$', blog_postDetailView.as_view(), name='blog_post_detail'),
]

基础html，导航部分

Answer 1

将以下行放在url_patterns列表的末尾，如

urlpatterns = [
     #all other urls, 
     url(r'', include('blog.urls')),
]

或

url(r'^blogdetail/', include('blog.urls')),

未找到Django页面404，引发者：blog.views.blog_postDetailView
