Hey everyone,
-- One last try. I've given up on django-locking, and am now trying django-concurrency because it's more modern and more likely to work on Django 1.6.8's admin interface.
The documentation is very basic and doesn't actually give any examples, so I'm not sure if I've missed something, but I'm getting this exception when I modify my ConfigurationAdmin class to inherit from ConcurrentModelAdmin as the documentation discusses.
class ConfigurationAdmin(ConcurrentModelAdmin):
form = forms.ConfigurationForm
change_list_template = 'admin/configuration/change_list.html'
...
Internal Server Error: /test/common/configuration/
Traceback (most recent call last):

I also changed {{ obj.pk }}
to {{ obj|identity }}
in delete_selected_confirmation.html
as directed in the documentation.
Does anyone know how to set this project up? Any help at all would be greatly appreciated.
Thanks!
Ian
