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

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.:

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, 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, 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 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

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

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

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, 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

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 have a ruby class that will be used sometimes from within rails, and sometimes from without (not in the context of a running rails application). It will reference models within the rails app, and It may be run manually, or may be scheduled via Cron (though I may look at RailsCron as well). I''ve seen help on the Wiki for using models outside of Rails (like this

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

Hello, I am planning to build a bigger Internet platform and actually evaluating Java EE and Rails. I have a lot of Java experience and I am quite new to Rails. After playing some weeks with Rails I am sure that it is a mature web framework and I really like the productivtity of Rails. One of the key advantages is that new developers will understand this platform much quicker than all the Java

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 have previously used railscron for server-side manipulation of the database but had a heap of trouble working with it. BackgrounDRB was suggested to me by a friend. I upload some files via acts_as_attachment and these go lie in a dir structure that i desire. What I want from the background process is to periodically (not user initiated) do some file-structure manipulation i.e. I want to

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, 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/
