similar to: Error in send_file

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! Today I needed to implement some controller code, that uses send_file() to send image data. How can this be tested / specified with RSpec? bye, Tobias

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 just replied to someone about using send_file and while I was testing my solution I figured out that the controllers "current working dir" appears to be the root of the app. Then I saw a reply that Ezra sent to someone where he used RAILS_ROOT and I thought "duh, I''ve seen that before... shoulda used that". But, when I had an action print out RAILS_ROOT

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 =>

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

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 =>

I''m trying to build a simple proxy to Amazon S3 that would allow a client to request a url that gets mapped to a S3 Object by Rails and streamed back to the client. For S3 integration, I use the highly recommended gem AWS::S3 (http://amazon.rubyforge.org/), and to send a file, I simply use the send_file function. The concept works BUT the I can''t get the file to be sent as

Hi, I am using send_file to allow users to download files from my website, please see code beloe: def download_document send_file("#{RAILS_ROOT}/public/test_form.pdf", :filename => "test.pdf", :type => ''application/pdf'', :disposition => ''attachment'', :streaming

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

Hi, I''m developing a Rails application that (amongst other things) lets users download media files. These files range in size from a few kilobytes up to several gigabytes. All this development is taking place with Rails 1.0 on a Solaris host with Ruby 1.8.2 and Rails mode set to "development". I''m using the Rails send_file method to send each file with these

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, 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):

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 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",

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:

Or perhaps I am stumbling in newbie fashion (tho I have active_merchant and a store site basically up and running in development mode - still I don''t feel I always understand what is going on.) So, when I have send_file(filename, :type => ''application/x-zip'') redirect :action => index the send_file seems to hang, rather than complete. I''m deducing

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''ve been using send_file in my Rails application with WEBrick happily to send files of various sizes and kinds. The same code fails to send anything but a 500 error when run under Apache, and a log file message "warning: syswrite for buffered IO". Looking back through the mailing list archives I see that there have been send_file bugs in the past. Can some knowledgeable
