Hi, I have a rails application where I respond to a request by fetching image urls from various web api calls and need to display them as they come available. I am able to display all the images once I get them all, but that causes an unacceptable delay for my user. One approach I am trying is, from my controller, set an @image variable, and then pass in a block to the model that retrieves the

I''m attempting to use send_file to send an image file from public/images. The file is world readable. I keep getting the following error: A ActionController::MissingFile occurred in account#current_logo: Cannot read file public/images/logo.png /usr/lib/ruby/gems/1.8/gems/actionpack-1.12.1/lib/action_controller/streaming.rb:55:in `send_file'' I''ve tried supplying

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. The problem is that if I use send_file to send the zip off to the user, I cannot delete the file afterwards as it seems send_file forks off another process and deletes the file before the

I''m trying to add a link to download a zip file. I created a controller method that makes the call to send_file: def getzip send_file ''file.zip'' end When I navigate to this link I get a MissingFile exception. The file definitely exists (and U triple-checked paths and spelling) and the permissions are 644. I tried moving it to the /public folder and updating the

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

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:

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 =>

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

Does anybody know if there is a big performance/time cost difference between these two methods of serving a file: ------------------------------- #1 ----------------------------------------- send_file "test.png", :type => ''image/png'', :disposition => ''inline'' ------------------------------- #2------------------------------------------

On my site I''m allowing users to upload songs in mp3 format. Members can download the full song, but on public pages I would like to use a flash player to play a 30 second clip of the song and/or allow downloading of a 30 second mp3 snippet. The songs are stored above the web root directory, and I use the send_file method for the full file downloads for members. My question is,

I am using rmagick to convert files stored as a tiff to either pdf or jpg for display to the user. A snippet of test code from the controller follows. It works OK. ( it does need a sanitizer ) require RMagick def pdf @sdoc = Sdoc.find(params[:id]) @fname = ''/var/www/images/'' + @sdoc.fname @nf = Magick::ImageList.new(@fname)

Hi, looking for something that simple, but can''t find it. I got: outfile = File.open(''teams.txt'', ''wb'') CSV::Writer.generate(outfile) do |csv| for team in @teams csv << [team.id, team.name] end end outfile.close send_file "teams.txt", :filename => "teams.txt",:disposition =>

Hello, We are using JRuby 1.5.1/ruby 1.8.7/Rails 2.3.8 with a GWT front end. I''m having an issue when attempting to send a server side .csv file to the user using rails send_file. my code is: send_file(path_to_file, type=>''text/csv'') While this is returning fine with an http status of 200, the client side save as dialog is never opening for the user to receive

I know that Zed has made mention of the fact that using RMagick with mongrel and rails is a bad thing. I''m currently using FlexImage (which in turn uses RMagick) on my application and really haven''t had too many problems. We get a restart for memory usage every 8-10 hours on one mongrel of twelve running, but I''m not sure if that''s an RMagick issue. Either way,

I have a form_remote_tag that calls a method to print out a csv file for download. If I tell the form_remote_tag to update a div the data comes up in that div, but otherwise I can''t get the browser to acknowledge the sent file. >From view: <%= form_remote_tag :url => {:action => "csv_dump" }%> <%= submit_tag "Download Complete List" ,:name

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
