similar to: ActiveRecord gotcha with references?

Hey guys, I just came across this oddity, not sure what to make of it yet, but I think it might be incorrect behavior. When doing a @inst.find(:all, :include => ["hometeam", "awayteam"] ...) hometeam and awayteam are two references from a belongs_to that is of the same model and of the same table. I will get a pgerror stating that "matches", which is

I am a newbie and I am running into a problem which I cant understand. I have a table called ''privileges'' which has the following fields CREATE TABLE `sdqualplanner`.`privileges` ( `id` int(10) unsigned NOT NULL auto_increment, `name` varchar(20) NOT NULL default '''', `description` varchar(100) NOT NULL default '''', `section_id`

In my view, I have: <%= select("division_filter", "division_id", Division.find_all.collect {|p| [ p.division, p.id ] }, { :include_blank => true }) %> How do I retrieve the division_id in my controller? -- Posted via http://www.ruby-forum.com/.

Hi CAS is a centralized authentication service, and the cas_auth filter can be installed to automatically make your web application authenticate against a CAS server. The SVN path to the plugin is http://svn.ki.se/rails/plugins/cas_auth and a homepage with some information can be found at http://opensource.ki.se/casauth.html For use, just install the plugin in your application and set

Hi, I''ve created some extensions to script.aculo.us InPlaceEditor, allowing the use of either server-driven, or local autocompletion. I''ve also created new helper methods in Rails for this functionality. My question is, is there any interest that I package this and make it available as a plugin, or something like that?

Hi All I have a requirement to consume a 3rd party web service from my Rails application.

i am trying to create a system so that different users have different priviliges on my application. i was going to modify my authorize function so that i could pass the required role to it and have it check the current user for that role. i am using before_filter and would like to have just one function instead of writing one for each role like so: authorize(role) instead of:

Hello, Does anyone here know if Ruby 1.8.6 fixes the "BreakPointer" problem in Rails? The reason I ask is that I have been working with Curt Hibb''s InstantRails in Window (at last I have found a usable Rails system on Windows). Currently, I am on InstantRails 1.6, but Curt has made available InstantRails 1.7 which has the following components: Instant Rails 1.7 contains the

I would like to announce my plugin Swedish Rails. Rails provide many goodies and helpers for you, but some of these are dependant on your user interface being in english. Date controls, for example. Pluralization is another. And have you ever tried to capitalize a string with Swedish letters in them? Then you know it doesn''t work that well. Until now, that is. You install this

Hi All, I am using R 2.11.0 on a Ubuntu machine. I have a time series data set and want to run rolling regressions with it. Any suggestions would be useful. Here are the details: (1) I convert relevant variables into time series objects and compute first differences: vad <- ts(data$ALLGVA/data$GDPDEF, start=1948, frequency=1) emp <- ts(data$ALLEMP, start=1948, frequency=1) vad.dif1 <-

Hi I''m in the process of deciding how a plugin should be designed to make configuration as easy as possible. Right now I require the plugin from init.rb, and set some configuration options (as class attribute accessors) from environment.rb. Then I tried setting these from environments/development.rb instead, and to my surprise this didn''t work. It said the class in question

Hi railers, What do you do when you must use a plugin in a rails app that is under subversion? I think that an approach is simply install a version of the plugin, and once all the test pass, commit the plugin itself to the repository, inside the /vendor/ of the app. If a new version of the plugin is released, your app is still using the working one (although the new version could work too).

Hello, I am switching to R from Stata and I am having particular trouble with the transition from Stata's 'xtabond' and 'ivreg' commands to the "plm" package. I am trying to replicate some of the dynamic panel data work using the UK Employment data in Arellano and Bond (1991) and available as 'EmplUK' under the 'plm' package. I have been

Hello list, I'm following the paper (http://www.jstatsoft.org/v27/i02/paper) on how to use "plm" to run panel regressions, and am having trouble with what I believe should be something very basic. When I run the command (p.9 in the paper): R> dynformula(emp~wage+capital,log=list(capital=FALSE,TRUE),lag=list(emp=2,c(2,3)),diff=list(FALSE,capital=TRUE)) I see: emp ~ wage +

Hi Rails AJAX controls are very handy, and the InPlaceEditor is probably one of the easiest and most neat of them all. But, it doesn''t do autocompletion. I''ve rectified that situation. The plugin provides a few new helpers and a new JavaScript-file that extends the Ajax.InPlaceEditor with local and remote Autocompletion features. So, just install the plugin, include the

Dear Ivo, dear list, (see: Message: 70 Date: Thu, 26 Mar 2009 21:39:19 +0000 From: ivowel at gmail.com Subject: [R] pgmm (Blundell-Bond) sample needed) I think I finally figured out how to replicate your supersimple GMM example with pgmm() so as to get the very same results as Stata. Having no other regressors in the formula initially drove me crazy. This was a case where simpler models are
