Does anyone see any problem with this form? - form_remote_for(Photo.new, :html => {:multipart => true, :target => :uploader}) do |f| .form_element = f.label :photo = f.file_field :collateral = hidden_field_tag :container_id, @shoot.id = hidden_field_tag :container_type, @shoot.class.name .form_element = f.submit ''Add Photos'' The photo has a paperclip attachment called collateral, and a double polymorphic relation with container (which can be a shoot, model or photographer). At the bottom of the page is an iframe with the id and name ''uploader''. However, when submitted via AJAX, it never serializes the file_field: both the development log and firebug both only show the hidden params being passed. It works fine as a form_for, however. I''m using 2.2.2 on OSX 10.5.6 and the responds_to_parent plugin to, well, respond.
