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. <https://django-concurrency.readthedocs.org/en/latest/admin.html> class ConfigurationAdmin(ConcurrentModelAdmin): form = forms.ConfigurationForm change_list_template = 'admin/configuration/change_list.html' ...

Any help at all would be greatly appreciated. Thanks! Ian -- You received this message because you are subscribed to the Google Groups "Django users" group.
