我是python和Django的新手并使用win10系统。
Django版本:1.9.4。和Python版本:3.6.3。

这是我的音乐\ urls.py:
from django.conf.urls import url
from . import views
app_name = 'music'
urlpatterns = [
url(r'^$', views.index, name='index'),
url(r'^register/$', views.register, name='register'),
url(r'^login_user/$', views.login_user, name='login_user'),
url(r'^logout_user/$', views.logout_user, name='logout_user'),

from django.conf.urls.static import static
urlpatterns = [
url(r'^admin/', admin.site.urls),
url(r'^music/', include('music.urls'),),

]
if settings.DEBUG:
urlpatterns += static(settings.STATIC_URL, document_root=settings.STATIC_ROOT)
urlpatterns += static(settings.MEDIA_URL, document_root=settings.MEDIA_ROOT)
如何解决这个问题?
答案 0 :(得分:1)
将主要urls.py中的音乐应用网址命名为:
url(r'^music/', include('music.urls'), namespace="music"),
如果在slash config的设置中没有处理过斜杠,请从网址模式中删除尾部斜杠
url(r'^(?P<album_id>[0-9]+)$', views.detail, name='detail'),
您可以在模板中引用这些命名的url模式,如下所示:
{% url 'music:detail' album.id %}
答案 1 :(得分:0)
你正在某处调用website.index
。将其更改为music:index
,其中music
为app_name
,index
为网址名称。
