Django，找不到頁面404

Question

當我開始開發服務器時

Page not found (404)
Request Method: GET
Request URL:    http://127.0.0.1:8000/

然后

Using the URLconf defined in mysite.urls, Django tried these URL patterns, in this order:

^admin/
^blog/
The empty path didn't match any of these.

mysite.urls.py

urlpatterns = [
 url(r'^admin/', admin.site.urls),
 url(r'^blog/', include('blog.urls')),
]

博客/urls.py

pp_name = 'blog'
urlpatterns = [
# post views
url(r'^$', views.post_list, name='post_list'),
url(r'^(?P<year>\d{4})/(?P<month>\d{2})/(?P<day>\d{2})/'\
r'(?P<post>[-\w]+)/$',
views.post_detail,
name='post_detail'),
]

我懷疑我的模板有問題這是樹所提供的

Answer 1

您的網址與主網址中的/路徑不匹配。 向url regex r'^$'添加一些視圖，然后它將起作用。 例如，以名為home的視圖為例。 請進口相關進口。

from . import views    

urlpatterns = [ 
        url(r'^$', views.home, name='home'),
        url(r'^admin/', admin.site.urls),
        url(r'^blog/', include('blog.urls')),
]

或者你可以喜歡

urlpatterns = [ 
     url(r'^admin/', admin.site.urls),
     url(r'^', include('blog.urls')),
]

Answer 2

要使用根站點路徑，應將urlpatterns更改為此：

urlpatterns = [
 url(r'^admin/', admin.site.urls),
 url(r'^', include('blog.urls')),
]

否則，您仍然可以通過http://127.0.0.1:8000/blog url獲得視圖。
