Hi, During reading and playing with django tutorials and documents, I've found that every user who has modify / delete permission can modify / delete items other user had created. It may be acceptable in some situations but there is other situations that users should modify / delete items of their own like portals. So, followings are my suggestion...
If model has one-to-many relationship referring user id field, item of that model belongs to user who created and no one else can modify / delete that item in admin mode. List_object view should list user's own items only. If model has one-to-many relationship referring group id field, item of that model belings to that group of users so member of that group can modify / delete that item. (This is separate request) Group has anonymous argument and when given true value, history does not record who changed that item. <- this is for discussion of matters, frankly and secretely. ;) Django is really great. Sorry for not implementing what I've suggested. I really would like to, if I could do. Suhku.
