Redirects in Django urls including parameters

A change of url schemata forced me to redirect some urls in my Django app. I wanted to use reverse, RedirectView and url parameters.

The View:

from django.views.generic import RedirectView
from django.core.urlresolvers import reverse_lazy

class RedirectViewCustom(RedirectView):
  """view to redirect including all named parameters to a specific lazy url name"""

  def get_redirect_url(self, **kwargs):
    params = self.kwargs
    name = self.kwargs.get('redirectname')
    if name:
      del params['redirectname']
      return reverse_lazy(name, kwargs=params)
    else:
      raise ValueError, "redirectname not set in RedirectViewCustom call."

In urls.py:

url(r'^old-name/(?P<slug>[a-zA-Z]+)/(?P<param>[a-zA-Z0-9-\-]+)/$',
  RedirectViewCustom.as_view(),
  kwargs={'redirectname':'some-name'}),

Tested with Django 1.4.
