python - 使用 anchor 标记调用 View django

Question

项目.urls

from django.contrib import admin
from django.conf.urls import include, url, patterns
from django.conf.urls.static import static
from django.conf import settings
from django.contrib.staticfiles.urls import staticfiles_urlpatterns
admin.autodiscover()

urlpatterns = patterns('',
    url(r'^$', include('app.urls', namespace = 'app')),
)+ static(settings.STATIC_URL, document_root=settings.STATIC_ROOT)

urlpatterns += staticfiles_urlpatterns()

app.urls

urlpatterns = patterns('',
# ex: /polls/,
 url(r'^', index.as_view(), name = 'index'),
 url(r'^contact/', ContactMail.as_view(), name = 'contact'),
# url(r'^register/', register.as_view(), name = 'register'),
# url(r'^login/', login_user.as_view(), name = 'login'),

)+ static(settings.STATIC_URL, document_root=settings.STATIC_ROOT)

urlpatterns += staticfiles_urlpatterns()

html

<a class="page-scroll" href="{% url 'app:contact' %}">Contact</a>

我得到错误:

Reverse for 'contact' with arguments '()' and keyword arguments '{}' not found. 1 pattern(s) tried: [u'$contact/']

知道为什么会这样吗？

提前致谢!

您已通过以 $ 结尾的正则表达式包含应用程序网址，因此包含的任何内容都不会匹配。不要那样做。

url(r'^', include('app.urls', namespace = 'app')),
