from django.conf import settings


admin.autodiscover()

urlpatterns = patterns('',    
    url(r'^admin/', include(admin.site.urls)),
    url(r'^hello/$', hello),

        (r'images/(?P<path>.*)', 'serve', {'document_root': settings.MEDIA_ROOT}),       
    )

Answer 1

如果产品是您的视图名称，则猜测{％url product％}应为{％url'产品'％}。

修改：同时使用视图'product.views.product'的全名。

反向''带参数'（）'和关键字参数'{}'找不到
