success_url in UpdateView, based on passed value

Question

How can I set success_url based on a parameter?
I really want to go back to where I came from, not some static place. In pseudo code:

url(r

Define get_absolute_url(self) on your model. Example

class Poll(models.Model):
    question = models.CharField(max_length=100)
    slug = models.SlugField(max_length=50)
    # etc ...

    def get_absolute_url(self):
        return reverse('poll', args=[self.slug])

If your PollUpdateView(UpdateView) loads an instance of that model as object, it will by default look for a get_absolute_url() method to figure out where to redirect to after the POST. Then

url(r'^polls/(?P\w+)/, UpdateView.as_view(
    model=Poll, template_name='generic_form_popup.html'),

should do.
