And ... yes there does seem to be a better way.
Define own version of "changelist_view" e.g.:
def changelist_view(self, request, extra_context=None):
extra_context={ 'has_delete_permission': self.has_delete_permission
(request) }
return super(MyCommentsAdmin, self).changelist_view(request,
extra_context)
However - as this post suggests - http://bit.ly/7ZrKHl - is this
thread safe?
Thanks for any thoughts anyone.
