hi,
I am porting an app from 1.2.5 to 2.0.2 and I am having problems with file
uploads. The form fields look like this:
<%= ''Add attachment''.t %>: <%= file_field
''attachments'', "upload#{id}", :size =>
''40'' %>
The old code expects params[:attachments]["upload#{i}"] to be an
object (File?)
with a method "original_filename".
I am using ajax (and previously didn''t):
<% form_remote_tag(:url => url_for(:controller => :mex, :action =>
:submit_answer, :id => mex_exercise.id), :update =>
"answer_#{mex_exercise.id}", :html => {:multipart =>
mex_exercise.num_attachments_allowed > 0}) do %>
(num_attachments_allowed is > 0 and I see the enctype-attribute:
<form action="/en/mex/submit_answer/46"
enctype="multipart/form-data" method="post"
onsubmit="new Ajax.Updater(''answer_46'',
''/en/mex/submit_answer/46'', {asynchronous:true,
evalScripts:true, parameters:Form.serialize(this) +
''&authenticity_token='' +
encodeURIComponent(''a5de291b429a9def0d4ff822d8e278172e472a28'')});
return false;"><div style="margin: 0pt; padding: 0pt;">)
Do I need to change anything because of ajax?
thanks,

There are tricks you can play with iframes and so on.

Either use a Flash uploader like swfupload.org (but if you''re not fairly fluent in Javascript, i would advise against it), do know that the new session security measures cause problems if you want the upload to be authenticated or search for the responds_to_parent plugin and follow the instructions.

I also use v2.0.2 and have problem with remote file upload. I followed the instructions from this page http://khamsouk.souvanlasy.com/2007/5/1/ajax-file-uploads-in-rails-using-attachment_fu-and-responds_to_parent and getting error undefined method `content_type'' in vendor/plugins/attachment_fu/lib/technoweenie/attachment_fu.rb:260:in `uploaded_data anybody handled this problem in rails 2 ?
