Using user.profile.update_attributes({name: 'some name'}) just updates the current profile as expected. But in that case I'm

def update @album = Album.find(params[:id]) if @album.update_attributes(params[:album]) redirect_to(:action=>'list') else render(:action=>'edit') end end A Rails 1.1.6 tutorial that I'm covering recommends using the update_attributes method for updating a model, as in the example code from my controller listed above.
