Question

The urlconf and view is as follows:

url(r'^register/$',
    register,
    { 'backend': 'registration.backends.default.DefaultBackend' },
    name='registration_register'),



def register(request, backend, success_url=None, form_class=None,
             disallowed_url='registration_disallowed',
             template_name='registration/registration_form.html',
             extra_context=None):

What i want to do is redirect users to the register page and specify a success_url. I tried reverse(‘registration.views.register’, kwargs={‘success_url’:’/test/’ }) but that doesn’t seem to work. I’ve been trying for hours and can’t get my mind around getting it right. Thanks

If you want to be able to specify reverse() with parameters, those parameters have to be defined in the URL configuration itself (regexp). Something like:

url(r'^register/(?P<success_url>[\w\/]+)/$',
    register,
    { 'backend': 'registration.backends.default.DefaultBackend' },
    name='registration_register'),

You can wrap that URL section in ()? to make it optional (So that it matches just simple register/ too)
The difference between args and kwargs is that with args you can specify unnamed/named URL params while with kwargs only named.
So:

r'^register/(?P<success_url>\w+)/$'
reverse('url_name', args=[my_success_url])
reverse('url_name', kwargs={'success_url': my_success_url}) // both work and do the same

r'^register/(\w+)/$'
reverse('url_name', args=[my_success_url]) // only this works

Edit:
For success_url params, if you want to be able to match any full relative URL, including possible GET params in the relative URL, the actual regexp could get pretty complex.
Something like (untested):

r'^register/(?P<success_url>[\w\/]+(((\?)([a-zA-Z]*=\w*)){1}((&)([a-zA-Z]*=\w*))*)?)/$'
