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 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" end def download @photo =

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

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

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)

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:

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):

Lighthouse ticket: https://rails.lighthouseapp.com/projects/8994-ruby-on-rails/tickets/4452 I have recently been working on some gems that utilize ActiveSupport::Cache and ran into some issues with the different implementations handling the same functionality differently. One of the issues was that I couldn''t rely on expiring entries with the :expires_in option. MemCacheStore takes this

Hi! What HTTP headers do I have to sent to make the browser cache the output of an action? I tried: request.delete(''Cache-control'') but no luck. It''s an action that sends an image to the browser, hence I need that. Thanks, Rob

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

Hi all, I''m (STILL) plugging away trying to get rails to work under Apache2 Rails 0.9.5 Apache 2, OS Mandrake Linux 10.1 Apache is already running other stuff on /pluto/ and /localhost/ so I wish to install a new virtual host for rails to avoid upsetting anything. Added rails to my hosts file, and edited conf/Vhosts.conf to contain NameVirtualHost 192.168.0.254 <VirtualHost

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

Has anyone managed to use send_file with :stream => true? I''m currently still developing using Rails 1.1.2 on windows xp so might be OS problem. But google results show this also happen on linux hosts. I think using send_file with :stream => false is pointless. Since send_data does exactly the same thing. Or am I mistaken? Thanks. -- Posted via http://www.ruby-forum.com/.

Hello, I use Ruby on Rails to generate images, which are delivered via mod_fastcgi to apache2. These images should be cached using mod_cache and mod_disk_cache. But it does not work. In Rails I set my http headers like this: expires_in 30.hours, :private => false @response.headers[''Last-Modified''] = im.serie.received

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

I have the following: MODEL: def self.get_tag_cloud Rails.cache.fetch(''fetish_tag_cloud'', :expires_in => 1.hour) do find(:all, :conditions => [ "approved_for_tag_cloud = true"], :order => "LTRIM(name)") end end CONTROLLER: def index @fetishes = Fetish.get_tag_cloud end VIEW: .... <% @fetishes.each do |fetish| -%>

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

Does Rails automatically set an EXPIRE attribute on keys when working with Redis, or will an old key sit there forever if it''s never manually cleared out? This is mostly a concern when using ActiveModel''s "cache_key": <%= cache @post do %> The cache-key will be something like views/posts/744-20120613070958 . When the post is updated, and therefore gets a new
