I'm trying to get django-register to work on my website but I keep getting this error which I do not understand

I'm using django 1.6 on Python 3.3

This is my Urls.py for my project

urlpatterns = patterns('',
    (r'^ImageUpload/', include('ImageUpload.urls')),
    (r'^accounts/', include('registration.backends.default.urls')),
    (r'^$', RedirectView.as_view(url='/ImageUpload/list/')), # Just for ease of use.
) + static(settings.MEDIA_URL, document_root=settings.MEDIA_ROOT)

Can someone explain what the error means please?

回答1:

Its complaining about line no.14 because Django is unable to determine the url named as "index" in your urls.py files. I don't see a URL named as "index" above. Where/What is the URL pattern for your home page?

回答2:

This happens when the URL match expression has a parameter but there are none passed in with the reverse in the template.
