@sskylar When I'm logged out and try to visit a private item's permalink page, it throws a Dropmark::Error::NotFound exception rather than Dropmark::Error::Forbidden (like it does when trying to visit a private collection).
I think this is a bug? This is how I'm writing it:
begin
@item = Dropmark::Item.find(params[:id])
@collection = Dropmark::Collection.find(params[:collection_id], include_items: true)
rescue Dropmark::Error::Forbidden => e
redirect "/login?redirect=#{request.url}"
end
