These can be done using built in permissions and groups
Something like this might work for the rest:
class NewsAdmin(models.Model):
def get_queryset(self, request):
queryset = super(NewsAdmin, self).get_queryset(request):
if request.user.groups.filter(name="Author").exist(): # is the
user an author?
queryset = queryset.filter(author=self.user) # only allow
users to edit their own posts
return queryset
def get_readonly_fields(self, request, obj=None):
readonly_fields = super(NewsAdmin, self).get_readonly_field(request,
obj)
if request.user.groups.filter(name="Author").exist(): # is the
user an author?
readonly_fields += ['published'] # don't allow authors to
change the publish status
return readonly_fields
