Ruby on Rails

Hi,
I am uploading a PDF file using paper clip. File get uploaded
successfully. If I try to view the file directly from file system it is
opening.
I have to open the file from application so I have written following
code.
View Code:-
<%= link_to 'View Attachment', {:action=>"show_attachment",
:id=>user.id} %>

Controller Code:-
def show_attachment
@user=User.find(params[:id])
send_data(@user.attachment.url, :type => "application/pdf",
:filename => "attachment.pdf", :disposition => 'attachment')
end

Whenever I run the application and click on 'View Attachment' link it
opens the pop up which ask for either save it or open it. I click on
"OK", it starts to download pdf file but ends with saying
"Adobe Reader could not open "attachment-4.pdf" beacuse either it not
supported file type or file has been damaged."

Can anyone tell me what is the issue?
I can see the pdf file from the uploaded location.

Thanks,
Tushar
