What do I use for CONTACTS_IMPORT_CALLBACK in django-friends friends application?

I am trying to 开发者_JAVA技巧figure out what is needed for the CONTACTS_IMPORT_CALLBACK variable in django-friends or django-contacts-import applications (contact import is built from friends). I have tried view models, etc.. but everything throws errors. Neither application has documentation so I am just grasping at straws for what is needed. Can anyone point me in the right direction?

I don't remember this specific setting. but knowing pinax and seeing the name, I think this is the method, that gets called after you have imported contacts from email.

To solve this error, you can just define a dummy method in any file and point your import call back to that, if setting this to an empty string still throws an error.
