Changes between Initial Version and Version 9 of Ticket #19044

-              initial
+              v9
 Let's say I have object with parent set and once object is deleted, browser should be redirected to parent page.
 Expected way to work is:
+url(r'^object/(?P<pk>\d+)/delete/$', DeleteView.as_view(model=Object, success_url='/parent/%(parent_id)d/'), name='object_delete'),
+{{{
+#!python
+url(r'^object/(?P<pk>\d+)/delete/$', DeleteView.as_view(model=Object, success_url='/parent/%(parent_id)d/'), name='object_delete')
+}}}
 This can be achieved by evaluating success_url first and then deleting object:
+{{{
+#!python
 class DeletionMixin(object):
     """
 …
             raise ImproperlyConfigured(
                 "No URL to redirect to. Provide a success_url.")
+}}}
