similar to: running a background task/thread in rails?

Hi, I would like to start running a background procedure once a user logs in to his account on the website. For this I am considering using the RailsCron object. However, I am not able to download it. I am new to Rails. Can someone give me the excat command I should use to get RailsCron? Can someone suggest a better way of running a procedure in the background? Thanks -Yash -- Posted via

I received feedback from some of you, saying that it would be cool if RailsCron was even easier to manage. So I implemented a graceful start/restart inside of the plugin''s init.rb. If you don''t like it, comment it out and send me the feedback. Also, I finished an update to RailsCron that allows you to attach asynchronous processing methods to your ActiveRecord models. i.e.:

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, like many of you, have been searching for a good way to handle running long processes in Rails. So I rolled my own solution. I really want feedback! (I''ve tested this on very simple hello world examples, so don''t use it on anything production yet) . Grab the plugin: http://opensvn.csie.org/rails_cron Here''s the README: OVERVIEW ======== RailsCron is a way to

I updated RailsCron to fix some threading issues with ActiveRecord. Please update if you were on 0.2.1. Also, I am still working on a good unit test strategy (its tricky because I would think that the tests must occur over a lot of time), but haven''t had/made time to give it its due. If you have suggestions, please let me know. -- Kyle Maxwell Chief Technologist E Factor Media // FN

Hi All, I am developing a RoR app for managing community information and would like to have an summary of current events and interests mailed out monthly. The tickler email would be a basic summary of items and links back to the site. I would like to schedule the email delivery dates and have the app send out email to registered users that opted for this service. Once scheduled, a monthly

Does anyone know if there exists a Task Scheduler module in Ruby on Rails like in TurboGears below? http://www.turbogears.org/preview/docs/scheduler.html I''m using Ruby on Rails for a multiplayer online game and I want to set checks at regular intervals to see if users are still logged in etc. Thanks in advance -- Posted via http://www.ruby-forum.com/.

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

Hi all, I''ve set up RailsCron to send email reminders on a daily basis. My dev environment is Rails trunk on Debian Sarge, lighttpd running as a regular user. I''m having two issues: 1) When I run "rake cron_start", I get rake aborted! undefined method `blank?'' for "":String The "blank?" method is provided by Rails, so I''m

Hello, Is it possible to trigger an action in a controller when a table from database changes? I thought about using an utility like cron (railscron) to check every, e.g. 2 s, if the table changed, but I am wondering if there is a solution a bit more ''elegant'': to trigger an action exactly when the change is made. Best regards, -- Kuba Nowak

I''m using RailsCron, and it''s working out very well for me. However, I''m having one problem right now. I use the acts_as_background on one of my model objects. In order to get it to add the cron job to the table, I have to make sure the model is loaded in environment.rb. MyObject.load However, I''m running 2-3 fcgi process on my server. Most of the time when

Hi All, I''m a newbie for RoR. Now, I want to create a background task: send an email at 6 pm every day. How can I create this task?

Hi, Is the development of Rails Cron still active? most of the blog articles about it are unavailable and it hasn''t been updated for a long time. -- Abdur-Rahman Advany http://blog.railsdevelopment.com/

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.

Hi, maybe this is of use for some of you. RailsCron from http://svn.kylemaxwell.com/rails_cron/trunk does not work with an Oracle database out of the box. One thing is the usage of "start" as an attribute name, which is a reserved word in Oracle. The other thing is the datatype :text for the command column. This will become a CLOB which cannot be queried with an ActiveRecord select.

I am just getting into web servers/web applications and rails as well so bear with me. I am trying to write a web app that, based on a users input from the browser, will perform some task, and update the browser (ala ajax style) as needed and/or provide a way for the user to control the background task. Now, I have more experience with java servlets, which makes this easy enough for a beginner.

Hi all, The Rails book talks about running Rails under Apache, but is there a (relatively) easy way to deploy it to either Tomcat or JBoss? Is the CGI servlet the only option?

Hi, I''m trying to use RailsCron but keeping getting an error when I try to run it. I''m a beginner, so please use small words :) -bash-2.05b$ rake cron_start (in /home/jake/rails_sites/testsite) Syntax error: "&" unexpected The little bit I know about my environment: - RailsCron installed as a plug in (not gem, cause I''m on a shared host) - Debian Linux

Hey everyone, I''m still getting up to speed with Rails and Ruby. Is there a best practice technique for kicking off a thread to work on an activity in the background? Here''s the scenario: the user performs an action that triggers e-mails to be sent. (I''m using ActionMailer). My app acknowledges with a message to the user that the messages have been sent. I would

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).
