I''m playing around with Markaby and I decided to write a little blog app. I''m running into issues with forms however. If I use form_for the output of the form gets swallowed. For example: form_for :article, @article do |f| f.text_field :title f.check_box :published f.text_area :description f.text_field :pub_date f.text_area :content end gets rendered as an empty form
