Download a file

Hello
I have a file on the server and i want it to be downloadable by users
when they press on a link. i tried send_date, but it created a new
file instead of grabbing the existing one.
Here is the code

def download
send_data( path=>"public/files/test.doc" , :filename => "test.doc",
:type => "text/doc", :disposition => "attachment")
end

any help will be appreciated :slight_smile:
Thank you
Fred

Is this Rails, Merb, or...?

Anyway, if it is a framework, you might be better off asking the
community around the framework for hints and help. :wink:

Anyway, if you are using Rails you could use link_to, for example, as
described here:

Note: The code presented there could be vulnerable to code injection, so
proceed with caution.

Hello
It's Rails :slight_smile:
here is the view code:
<%= link_to "Download", { :action => "download" } , :post => true
%>

as i said in my previous thread, the file is already in the server; no
need to create, just download it. but i got a new file created
instead, with nothing in it.
Thank youg

Have you looked at the link I mentioned? It solves the exact problem you
have.
