similar to: Getting a MySQL deadlock when running RailsCron...

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, 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

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 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, 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 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

I''ve used Railscron in a couple instances, and I liked that fact that it has a rake task for checking the status of the process. Many times I use it in the admin interface to allow me to double check that everything is up and running. I couldn''t find one for backgroundrb, so here is a simple one. Probably obvious to everyone, and no doubt there is a better way to do it:

Hi, I am writing a client-server rails app. The client and server maintain similar databases. Periodically, I would like them to synchronize their databases. For this, in the application, once the user logs in, I want to spawn a background process at the client that first sends the client''s new data and then receives the server''s new data. I am thinking of using RailsCron for

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 =>

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

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

Hi Kyle, Thanks for your help so far. Now that I have it up and running, I''ve some behavior questions. I want to trigger an event just one time at a future time. I''m using some of your sample code to try this, but the behavior of some combinations of start, every, and finish behave in some unpredictable ways. 3 class RailsMaintainer 4 include ActsAsBackground

I''m yet another person looking to do some background Rails processing. >From post & the wiki, it looks like I should be using RailsCron. So I''m about to start playing. In parallel, I''d like to get some opinions re: database access. I have a table that I''d like to re-fresh periodically in the background. Is it safe, using RailsCron, to be accessing

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

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

Ezra, Sorry for inundating the list. In using the autostart, repeat_every, and first_run, I noticed a behaviour I didn''t expect. I would like the job to run starting at 2am, and then every 24 hours. So I set first_run to Time.now.beginning_of_day + 2.hours, and repeat_every to 24.hours. The problem is if backgroundrb starts up at 6am (due to a code change or server bump), then the

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/

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 am adding observers to some model objects. One of these uses RailsCron. RailsCron adds a class method to ActiveRecord::Base. Unfortunately, during the initialization phase, plugins aren't yet loaded, so I can't setup my observers in config/environment.rb, as suggested by the comments. What's a poor dev to do ? At the moment, I have fallen back to this: # Require all

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).
