file_send confused

Anyone see where I am going wrong here?

Error = undefined method `filename='

Model

class Upload < ActiveRecord::Base       def upload=(upload_field)         self.filename = upload_field.original_filename         self.content_type = upload_field.content_type.chomp         self.binary_data = upload_field.read       end

end

Controller

def upload     @upload = Upload.find(params[:id])     send_file(@upload.file,       :filename => @upload.name,       :type => @upload.content_type,       :disposition => "inline")   end

Form

<div id="UploadFileBox"> <b>Upload a file:<br/></b> <% form_tag({:action => 'create'}, :multipart => true) do %> <%= file_field("upload", "upload") %><%= submit_tag("Upload file") %> <% end %>

Thanks for any help. Lynn
