similar to: Sending a file *and* rendering a page

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

Hi all I made a pdf file in ruby and to display it used the method send_data like # send_data pdf.render, :filename => "Hello.pdf",:type => "application/pdf" # Now I want to open it in another window or as a popup. How can I achieve it? Thanks to all. Sainaba. -- Posted via http://www.ruby-forum.com/.

I have a controller that serves up images from a different location from /public/images/ by using send_file or send_data on /media/thumbs/ 38 for example In lighttpd I have: expire.url = ( "/media/" => "access 10 years", "/stylesheets/" => "access 10 years" , "/javascripts/" => "access 10 years",

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

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

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

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 =>

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

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------------------------------------------

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 that ? At minima don''t hardcode the beginning

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

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 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, 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/)

I MAY be able to derive something out of the present example given here : http://blog.codeinmotion.com/index.php/2006/12/22/pdf-generation-in-ruby-on-rails/ but this deals with filling out forms. Is there a simpler example that just allows you to talk to itext , send it some plain text and get back a pdf and then send that pdf to the user as downloadable / renderable data? -- Posted via

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! Is it possible to render the action within the after_filter method, or is the rendering performed before? I have something like this: class FooController after_filter :send def a @content=... end def b @content=.. end protected def send send_data(@content,...) end end However, when calling the action a or b, the @content doesn''t get sent, but instead

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 =>
