similar to: Ajax and Rails to manage long running server process (and file download)?

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

Hi, I''m using Rails 1.1 and the periodically_call_remote() helper to query the server for the progress of a long running action. I''m using the excellent new RJS partials to send a page.replace_html() to update the status information on the page--which works very well. When the action completes I''m also trying to send a redirect_to() by the same approach--which

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

Hi, My project has been happily using ActiveRecord outside of Rails for some time to populate various databases that are also used in Rails based websites. I''d like to bring AAF into this setup to index new records that are added to the databases as they''re added. Has anyone had any success in installing and using AAF with ActiveRecord but outside the Rails plugin support? I

Hi, We''re happily using Ferret through acts_as_ferret on a Rails website, but we have an issue with rebuilding indexes. The Rails project directories are on an NFS mounted volume and running Model.rebuld_index there seems to take 60-100 times longer than it does on a local filesystem (e.g. /tmp). What we''d like to do is rebuild our indexes in say /tmp, then copy them back when

I had a problem with the send_file method. I saw that some of you had the same problem but with no real solution/explanation first problem the :stream options, and not ''streaming'' as I see in some doc or book. the second problem : when you set :stream to true, there''s a use of syswrite that should not be. I detailed this in response to a ticket opened by stuart

Hi, I have an RoR application(parent) which is use to kick off other RoR applications(ajax scaffold based). I use win32-process Open4.popen4() to start the RoR applications. Untill recently I was using normal scaffold feature of Rails, and recently I migrated to Ajax Scaffold; After moving on to Ajax scaffold, when I try to start a RoR from my parent RoR, the application do get started, when I

Hi All, I have a Rails application that needs to be served from a Fedora Core 3 Linux server. The application runs well as a "plain" CGI application. My next step was to speed things up with FastCGI installed via "gem install fcgi". (version 0.8.6.1). That approach lead to this error in the fastcgi.crash.log: Dispatcher failed to catch: undefined method

Hello, I''m working on a download service which grants users a one-time-download access to files. The idea is to write an entry to a database table after a successful download that "locks" the download link for the user. After doing some quick tests with send_file I noticed that send_file does not block until the user has downloaded the full file, but proceeds with the

Hi, I''ve been happily using acts_as_ferret on a Rails site in development mode, but deploying to a production system causes some errors I haven''t been able to resolve. My production deployment setup is Apache/mongrel and I''m sharing the index directory across each deployment version by linking {current_path}/index to {shared_path}/index in the Capistrano setup. Edge

Hi, I''m using the application_helper.rb file to create some useful functions for generating links by name. I understand that functions defined in this file are available to all views, but what about constants defined in that module? Is there a best practice approach for doing this other than accessing each constant via ApplicationHelper::FOO? Stu

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

I need to get a simple file download to work. I want users to be able to click ''I agree'' after scrolling through a license agreement and the click initiates a download of some software which is in a zip file. I tried using send_file and had some problems I previously posted about. So I am trying to not use send_file. (If anyone can help me with my previous send_file post, that

Greetings, We are having some rights issues on Samba 3.6.18 running on Slackware64 14.0 (the official Slackware Package).

HI, I am directory listing and in that listing I have certain files and sub directories, now when I click on the files it should download that particular file but I am not able to accomplish it, and I have got to use send_file() method.

I''m using send_file to send rather large SWF files that I''d prefer the end browser to cache to reduce my bandwidth usage. I''ve used the method suggested by madrobby (http://mir.aculo.us/ 2005/08/28/internet-explorer-and-ajax-image-caching-woes) to try to catch the HTTP_IF_MODIFIED_SINCE request header, and then return HTTP 304 if necessary. However, this only seems to
