similar to: What to use to do an action every minute?

I''ve seen this come up a few times before on this list but never felt it got a satisfactory answer. What is the best way to execute timed actions? Examples include sending an email each week, calculating interest each day, or cleaning up your database or server files. This wiki page has some ideas, but these seem a bit extreme.

I want to be able to write a script in Ruby which regularly consumes an XML feed from a fixed source, re-formats it, produces a large file for web delivery, and updates a database with the contained information. It''s simple - just running a script from a cron job, and some basic data manipulation... But I''d prefer to use the Rails database mapping constructs than roll my

Does anyone know if it''s possible to do multiple AJAX responses to a single request in Rails? I did some googling but didn''t find anything extremely helpful.

Hi Everyone, I hope you guys can help me out. What is the best way to go about using a timer to execute events? I would like to execute a block of code every 24 hours (or at midnight - server time). Is this possible? What I am trying to get at is that I would like to create a new page every 24 hours and have that serve as my front page. Is it possible to route to this ''new

i want a daemon will check somthing every 10 minute how do this in rails? -- Posted via http://www.ruby-forum.com/.

So, what''s the status of this project? I''m a little confused. The documentation at http://backgroundrb.rubyforge.org seems out of date. It refers to http://svn.devjavu.com/backgroundrb/tags/release-0.2.1, which doesn''t work. All I want is a way to easily set up tasks that should run periodically. Some stuff should run every 10 seconds, some stuff once a day, etc.

I have a few maintenance programs that run periodically via cron. I learned how to use rails model files in those apps w/o much problem. However, the problem came about when one of my models, then many of my models began using plugins. Now I find that with each new plugin I use in my models, I have to go back to each of my utility apps and specifically require that plugin in order for

Hello, I need to put a script in place for updating a local database with a remote resource periodically. It should be started alongside the server (or inside it, whatever) and be run as long as the server running my rails app is up an running. Any thoughts on how to accomplish this? I have thought of editing the environment.rb file and placing the call to the script trigger there, but I wonder

I''ve been using script/runner to add and delete files from the database in response to inotify events. This works in theory, but is too slow to keep up with a large number of events in succession; I''m suspecting that the bottleneck is that script/runner has a huge startup cost. One thing I thought of was to queue inotify events, and call script/runner once a minute to clear the

Hi there I''m considering Rails for a new web-application planned to be built from scratch. The application has an extensive web front, and in fact most of the application is interfaced through that front and engaged through clients'' HTTP requests (i.e. the conventional way web-applications and "dynamic web-sites" work). However, some essential parts are supposed to

Hi, Going through the archive, and just keeping a general watch on this list seems to indicate that there are some issues using scheduling with backgroundrb. I need a worker that will perform some actions on an hourly interval. These actions will require access to several of the models in my application. I am currently using backgroundrb to handle processing of files, where I spawn a worker to

We are building a web-based application with Ruby on Rails and MySQL backend. The client now wants us to add various workflow features that will eventually expand into SOAP web services. These workflow features include tasks such as automatically sending reminders for due tasks, or if a particular set of information hasn''t been logged by a certain time to automatically send an email

I have a problem with Asterisk-bristuffed using a zaphfc card. I am located in the Netherlands, so I have an ISDN line from KPN. When I start Asterisk, and plug in the ISDN line, everything works perfectly for about 5 minutes. And then the ISDN line is down for 1 minute, and after that minute, the line comes back up and works for another 5 minutes. Every time the line goes down I get the error

Hi, I am using ruby 1.9.2 and rails 3 for my application. I have written a bash script which I want to run in cron. If I directly run the bash file it runs. If I run it through the cron I get the following error:- "/usr/local/rvm/rubies/ruby-1.9.2-p180/lib/ruby/site_ruby/1.9.1/rubygems/custom_require.rb:36:in `require'': no such file to load -- rails/commands/runner (LoadError) from

Say I want to send out an email once a day to people who''s name is "Bob". Would I use script/runner in conjunction with cron? Or is there another cool(er) way now? Thanks, Joe

Hello, The following cron job is failing to run: 00 16 * * * root ruby /home/nathan/rails/notifications/script/runner -e production Notifier.deliver_summary My understanding from the Rails Wiki is that this should do it.

I don''t know if anyone is using this but I just fixed a bunch of bugs, some big ones, and moved this project to RubyForge SVN servers. So you can get it here now: script/plugin install http://facebooker-mq.rubyforge.org/svn/trunk/facebooker-mq/ This is working great for me on a couple of projects. Here is the README Updated: 3/14/2008 Purpose: The purpose of FacebookerMQ is to

How are you guys handling threads or server processes that have to, for example, process the data in your application on a periodic basis? Cron jobs can do it and then run on the database. But, are there ways to launch threads within the rails application itself. I have heard of WebBrick ways, but I am working with lighttpd, fastcgi? (textdrive if you are really interested).

Hi, As part of a web application that I am writing I need to have something listening for any packets that are received on a particular port and then process the packets using some of my Rails models, hence I start the script via the ./script/runner command. This script always needs to be running, if it exits for any reason, I need it to start up again very quickly. Hence, I was considering
