uploadify and paperclip on rails 3.1 - paperclip

Question

i'm trying simply to upload a file using uploadify and paperclip.
This is index view:
<%- session_key = Rails.application.config.session_options[:key] -%>
$('#upload').uploadify({
'uploader' : 'uploadify.swf',
'script' : '/videos',
'cancelImg' : 'images/cancel.png',
'buttonText' : 'Add video!',
'folder' : '/public',
'auto' : true,
'scriptData' : {"<%= key = Rails.application.config.session_options[:key] %>" : "<%= cookies[key] %>",
"<%= request_forgery_protection_token %>" : "<%= form_authenticity_token %>",
},
onError : function (event, id, fileObj, errorObj) {
alert("error: " + errorObj.info);
}
});
This is my model:
class Video < ActiveRecord::Base
has_attached_file :source
validates_attachment_presence :source
end
...and this is my migration file:
class CreateVideos < ActiveRecord::Migration
def self.up
create_table :videos do |t|
t.string :source_content_type
t.string :source_file_name
t.integer :source_file_size
t.timestamps
end
end
def self.down
drop_table :videos
end
end
Now, when i upload a file, there aren't errors raised, neither client side, nor server side, but it looks like paperclip doesn't get the parameters sent him by uploadify. In fact, if i remove validation from model, resource is created without parameters.
In controller i add:
def create
logger.info(params.inspect) (1)
#video = Video.new(params[:video])
#video.save
logger.info #video.inspect (2)
end
In development.log (1) gives me
{"Filename"=>"prova.mov", "authenticity_token"=>"9q5w5LipGoBj Iac055OPbDofFU5FMbpEX675 RqOqs=", "folder"=>"/public", "_StreamVideo_Api_session"=>...
(2) without validation
#<Video id: 1, source_content_type: nil, source_file_name: nil, source_file_size: nil, created_at: "2011-10-10 12:12:38", updated_at: "2011-10-10 12:12:38">
(2) with validation
#<Video id: nil, source_content_type: nil, source_file_name: nil, source_file_size: nil, created_at: nil, updated_at: nil>
Where may be the problem?
Thank you in advance for answers!
In my view i put:
<h1>New video</h1>
<% form_for :video, :html => { :multipart => true } do |f| %>
<%= f.file_field :source%>
<% end %>
But http://localhost:3000/videos/new shows me only the title!!

Answer 1

the code looks ok, you should just add there encodeURI function. In Uploadify 2.1
it should work with:
'scriptData' : {
$('meta[name=csrf-param]').attr('content') : encodeURI(encodeURIComponent($('meta[name=csrf-token]').attr('content')))
}
With Uploadify 3.1:
'formData': {
$('meta[name=csrf-param]').attr('content') : encodeURI($('meta[name=csrf-token]').attr('content'))
}
