I am using image_tag to load an image that I''ve saved to the database (using attachment_fu if you''re curious but that''s probably not relevant here): VIEW <%= image_tag ''/photo/get_image/5'' %> CONTROLLER def get_image @photo=Photo.find(params[:id]) send_data(DbFile.find(@photo.db_file_id).data, :type =>

Guys & gals, I''m also learning RoR (using v2.3.4). I''ve got a basic scaffold working for image file creation, and - to a point - image file display. The send_data function is working in my controller - no problem. The model code is able to parse the uploaded file construct too. def show @image = Image.find(params[:id]) send_data(@image.binary_data, :type =>

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, I''m trying to use send_data to stream a file that is stored on my disk (not as a blob in the database.) So, this is what I''ve tried: send_data File.new(filename).read But, the file doesn''t download. I think send_data expects something other than a String (which is returned by File.read.) Anyone know how to get this working? The reason this is being done is to

Hi, I am using send_data to allow users to download files from the database but ran into a small problem, it seems that files upload fine but when they download only 64kb of the file is sent.

I''m trying to use send_data to send a simple text file. Every reference I can find says I can supply a MIME type with the ":type" option and that will determine the kind of file I get on the machine that downloads the file I''m sending.

I''ve got a rather long conditional statement that either displays a link_to(image_tag(blah)blah) or just an image_tag (i''ve edited it a bit to show the structure): <%= (article.score_from_user(:user_id => session[:user]) != -1) ? (link_to image_tag("/images/down_arrow_grey.jpg", :alt => "down"), :controller=>"article", :action =>
