Looks like this commit changed that function and the django-mongoengine module needs to reflect this. This only pertains to the admin interface.

This must be fixed now.

But deletion still doesn't work properly becouse of error in django/contrib/admin/utils.py model_format_dict. Which i have no idea how to fix properly.

If you want this to work - ideas and pull-requests is welcomed.
