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...

Dears, Got a controller witch do a send_data for displaying a chart. like : send_data(g.to_blob, :filename => "any.png", :type => ''image/png'', :disposition=> ''inline'') I actually do a <img src="http://myhost:3000/stats/make_graph" /> Is there any way more clean to do...

Short question: is there way to tell EM to actually send data after send_data call? I''m building a file transferring app. I send Mashal.dump''ed metadata first, and then - the file contents (chunked). I found a silly bug: receive_data() gets marshalled metadata and the first chunk of the file in a single variable. Like that: c1.send_data("meta")...

I am using eventmachine 0.8.1 on windows XP and am having very odd problems. This snippet of code gives the error that follows it. class EchoServer def receive_data data puts data send_data ">>>you sent: #{data}" if data =~ /quit/i puts "quitting" close_connection EventMachine::stop_event_loop end end end EventMachine::run { EventMachine::open_datagram_socket "127.0.0.99", port, EchoServer } Gives the...

Hi, for those with experience of Gruff module: suppose I want to send image from server straight to the browser (as example on gruff web site): send_data(g.to_blob, :disposition => ''inline'', :type => ''image/png'', :filename => "gruff.png") the server seems sending this binary data ok, but I am having trouble to display it properly: I have tried <%= link_...

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...

I''m a newbie having trouble using send_data to send a jpeg file to the browser for display in an html img tag. This is the relevant code from my controller (photos_controller.rb): def retrieve @photo = Photo.find(params[:id]) send_data File.read(@photo.abs_img_path), :type => "image/ jpeg", :disposition => "inline&...

So this is the original code I used, and it worked send_file ''vendor/sprites/not-found.png'', {:filename => "sprite-not-found.png", :type => "image/png", :disposition => "inline"} Now I switched it to this (going to be adding imageMagick) send_data File.read(''vendor/sprites/not-found.png''), {:filename => "soldier-not-found.png", :type => "image/png", :disposition => "inline"} But now instead of seeing my image I see the good ''ol broken image. I assume this is because an image...

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 using the basic rails code from the Agile book: #upload code in my sheet model def file=(document_field) sel...

Has anyone else had trouble using send_data with internet explorer. As usual things were working fine in firefox and safari until I tested in IE :). With the following code I''m seeing an image show up in firefox but the "X" indicating no image found in IE. Any ideas? @image_data = Image.find(:all, :conditions=>{:url...

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. Instead I ALWAYS get an XML file. here''s the code snippet:...

...display it alongside some other information on my ''edit'' page. I read the information here http://wiki.rubyonrails.com/rails/show/HowtoUploadFiles and that was really helpful. However, it still isn''t clear to me how I would get access to the image in my views if I use send_data. My naive reading of send_data is that you get a page with only the image on it. Hopefully I just misunderstand something here, because the next option in my queue is to try writing images out to public/images as temporary files and I''d really like to avoid doing that ;) So, can I use send...

I''m running a Rails application with WEBrick server. We are displaying an Image from the server to the Client (Browser). 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. But in case if the image gets changed on the server(File Name being the same), then even though i
