Errors while using paperclip in rails app

At the moment I try to replace attachment_fu fileuploading plugin with paperclip.

But there are some errors while uploading:

My controller looks like this:

def create
add_breadcrumb 'breadcrumb.upload_file', {:action => :new}

puts "BLUBBBBBBBBBBBBBBBBBBBBBBBBBBB"
puts params[:upload]

    @upload = Upload.create(params[:upload])
    @upload.lecturer_id = current_user.id
    if @upload.save
        flash[:notice] = I18n.t("flash.saved")
        redirect_to :action => :index
    else
        render :action => :new
    end
end

and my model like this:

puts has_attached_file :image, :default_url => :file_system
validates_attachment_content_type :image, :content_type => [:image, 'audio/mpeg', 'application/mp3', 'application/octet-stream']

While uploading I got this error:

ActiveRecord::UnknownAttributeError in UploadsController#create

unknown attribute: uploaded_data

app/controllers/uploads_controller.rb:24:in `create'
