First time on the browser everything looks fine, upon clicking the link, it contacts the server and displays in IE brwoser the image that was stored on the server.

Anyone know how to send a file/data to the user agent (download it) using #send_file or #send_data, *and* render a new page in the same action? This just sends the file and doesn''t render the page: def gimme ... send_data(our_data, :filename => ''output.csv'', :disposition => ''attachment'') end And this will give a Double-Render error:

My application accepts a form to create multiple large(100''s of MB) temporary files and then zip''s them up to send off to a user. I have the files constructed, and the zipping working.

Hi, I want to offer a CSV download of data in my Rails app (eg. An "Export to Excel" link to grab the current view of tabulated data). However, I can''t seem to break-out of the Rails framework to output this non-HTML data. Even if I eliminate my layout template from my view, the most basic view (no HTML) will still wrap the output in

Hi, Controller code: if params[:main_image] image = Image.new image.blob = params[:main_image].read @product.main_image.destroy if @product.main_image @product.main_image = image end When I try to display the image using send_data, I get the following error: ArgumentError (string contains null byte):

I''m trying to display a generated .png plot via send_data(), but it results in a server error "invalid byte sequence in US-ASCII" error. I''m pretty sure this means that I need to specify the encoding somewhere, but I haven''t been able to figure out where or how to do so. Some particulars: I''m running gnuplot through a pipe to generate a plot in .png

Hi all, A slightly hypothetical one here... but after Samba (Winbind actually)... looks up the list of AD server for a doman from DNS... what method does it use to decide which is the correct (most local?) domain controller to connect to/log in to?

Hi, I''m trying to figure out the best way to protect images uploaded by users who may wish to keep them private. For example, if they are uploaded in the default file_column location (/public/blah/blah/1/) then someone can simply type the URL http://www.blah.com/blah/blah/1 and get the image. I can store the images in a non-public directory in the rails app (ie: /railsapp/images/X/)
