similar to: RailsCron usage question

I didn''t find exactly an answer on this one, so I''d like to get a clarification from folks who live & breathe HABTM. class foo has_and_belongs_to_many :bars end class bar has_and_belongs_to_many :foos end (and yes, I have a bars_foos table in my db) def test_habtm bar = Bar.new foo = Foo.new foo.bars<<bar assert !foo.bars.empty? assert

I''m using Rails 1.1.x and it looks like the check_box form helper expects me to provide and object and method so it can determine if the checkbox should be checked or not. I''m having a couple of issues with this. note: I''m using UserEngine and adding a HABTM so that: class User < ActiveRecord::Base has_and_belongs_to_many :foos end class foo <

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, 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, 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''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

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

Hi, I'm trying to draw a 2D plot using multiple tints of red. The (simplified) setup is the following: || year | x | y || My idea is that each year is plotted with a different tint of red. Older year (lightest) -> Later year (darkest). I've managed to plot this with different scales of grays simply by doing: palette(gray(length(years):0/length(years))) before the plot and for each

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 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 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

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

OK, perhaps I wasnt clear in my previous posting. I am looking for either a SRPM for the CentOS 5.2 centos.plus kernel, or more likely, a diff from the kernel at kernel.org. I was pointed to the wiki, which MENTIONED a Source RPM, but didnt point to anywhere to find these for CentOS. All Ive been able to find are ISO's . I really dont need a bunch of tools that will complicate the problem,

Im trying to get a diskless boot set up under CentOS 5.2, and having no luck at all. I am to the point of running system-config-netboot, and whatever information I put in, I get an error message. Responding to the 2nd button on the first popup, which asks for NFS info, I put in the IP address of the current machine (the machine that will hold the boot images for the diskless machine) and the

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.:

This is probably a very noobish question, but if I want to create a function that allows an undetermined number of, say, numeric vectors to be fed to it, I would use: myfunction = function(...) { # Do something } Right? If so, how do I a) count the number of vectors "fed" to the function, and b) how do I treat those vectors as variables, e.g. for the call:

Application: DWFViewer.exe Wine 0.9.14 - mandriva 2006.0 This is Autocad's "free" viewer program for dwf files. I had to install IE6 first as a pre-requisite. I used the Wine recommended method of adding that one dll to the windows/system32 directory then ran ie6setup.exe to install it. The DWFViewer installed fine, but then when trying to run it this message came up: This

Sorry for the noobish question, but what kind of subscripts generate a SCEVCouldNotCompute from the SCEV engine? I tried for a while but I wasn't able to trigger that. 2011/11/20 Tobias Grosser <tobias at grosser.es>: > On 11/20/2011 03:01 AM, Marcello Maggioni wrote: >> >> 2011/11/19 Tobias Grosser<tobias at grosser.es>: >>> >>> On 11/18/2011
