No. It's a weakness of the otherwise very cunning shards mechanism that there is no way for it to get at local variables. Taggable could help, perhaps by including an empty partial (_other_columns.html.haml?) with some locals or by setting a @current_tag variable within the index-page loop. Neither approach is very pleasing, but it will take a while to arrive at a better solution that is also simple enough to live with. I need to clear up that index page anyway (as you can see from the 'node.level-1'). Would anyone like to suggest a best practice here? will
