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.:

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

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, I am new to ruby and to rails, but I like what I see so far. I have been working on a web app in java (servlets and JSPs) that, based on a request from the user, kicks off a thread in the background to perform a task (puts messages in an MQSeries queue). The thread object is stored in the session and I then allow the user to control the task from the browser(like stop it). Is the same

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

Got another question. It''s unclear to me what "every" means in the background function and how it relates to the RailsCron.create "every": >From README: RailsCron.create( :command => "Object.do_something()", :start => 2.minutes.from_now, :every => 12.hours, # default: 1.day :finish =>

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/.

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

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

Any suggestions on applications that involve alot of calcualtions on a fairly large data set? My app uses a set of raw data ~5k, applies some default/override rules on the raw data and does some calculations on the data in combination with a list of assumptions. A ranked list along with detailed metrics is generated. The end user can manipulate some of the rules and assumptions to generate

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/

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 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''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?

I''m looking for best practices / ideas on how to refresh large external data sources. What if your rails app relies on a large data set that you get via some service and it needs to be updated periodically. For instance, lets say your rails app uses weather report and airline flight information. You can get both data sets via some feed mechanism and you would like to use data that

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

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).

I have installed backgroundrb. I can start it. I have read everything I can get my hands on, and have read the list for a few months. I have written a worker, and am ready to start. This worker reads a queue, and processes it (sends queued emails). Sends 10, sleeps for a minute, sends 10 until done - very straightforward. My question is, what would be the best way to run this? I have
