If you have an object that you have paginated, you can get the number of pages with .total_pages: this will be the same as the number of the last page. Presumably when you're looking at the topic, you've already loaded it's replies anyway? eg @topic = Topic.find(params[:id]) @replies = @topic.replies.paginate(:page => 1, :per_page => 20) last_page = @replies.total_pages -- Posted via http://www.ruby-forum.com/. --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.
