similar to: How to organize models into modules

I love the query interface (ActiveMethod::QueryMethods), but one thing has bugged me: why doesn''t it generate calls for polymorphic associations? For example: class MyModel < ActiveRecord::Base belongs_to :parent, :polymorphic => true end I would expect: MyModel.where(:parent => a) to be equivalent to: MyModel.where("my_models.parent_id = ? AND

I get a crash when I try to link multiple modules registered in their individual contexts. Documentation for Linker::LinkModules doesn't mention anything about contexts, and the first link succeeds. But the second link crashes. Is this not the right way to merge such modules? If not, then what is the right way? In any case, documentation for Linker::LinkModules should say if contexts are

Please excuse yet another newbie question... I''m getting this error: MissingSourceFile in <controller not set>#<action not set> c:/program files/ruby/lib/ruby/gems/1.8/gems/actionpack-1.8.1/lib/action_controller/dependencies.rb:75:in `require_dependencies'': Missing model MyModel.rb From these lines of code: class MyModelController < ApplicationController

I want to start out with an apache class that will disable all modules except for a pre-defined list, thus establishing a baseline of active modules. Then as needed, other classes could enable a module that they require that would have been disabled by the baseline state. Its possible several classes may try to enable the same module (1 or more classes needing module1 could be on a single node)

Before I start, I''ve read the ActiveRecord docs on eager loading, but for the life of me, I can''t seem to get it working. What I mean by this, is that the eager query looks good (I can paste the sql dump, but it looks good to me - and runs well independantly), but it seems that I''m referencing the eagerly loaded data in a way that activerecord doesn''t

Does anyone know if it is possible to perform an ActiveRecord find by passing in an array? I would like to be able to do the following: MyModel.find(:all, :conditions => ["user_id in (?)", users]) The problem I run into is that the returned SQL contains the to_s() output of the User object, not the ids of those users. Is it possible to change this behavior? I attempted to

I''m still a newb but having fun - Any help on this problem will be much appreciated. I have mymodel Call.rb class Call < ActiveRecord::Base belongs_to :user has_many:visits, :dependent => :destroy has_many:visits do def latest find :all, :order => ''id DESC'', :limit => 3 end def all_latest find

So, our application has a large number of models at this point, and I''m getting a bit worried about people having to use long names, as well as clashes in the global namespace. More recently I wanted to add a new table with some STI subclasses of that table... module Portal end class Portal::Base < ActiveRecord::Base belongs_to :widget end However, Widget is a top level class,

This should be very easy, but alas, I'm very new to R. My end goal is to calculate p-values from arima(). Let's say I just ran this: > MyModel <- arima(y[1:58], order=c(1,0,0), xreg=MyData[1:58,7:14], > method="ML") > MyModel And I see: arima(x = y[1:58], order = c(1, 0, 0), xreg = MyData[1:58, 7:14], method = "ML") Coefficients: ar1

Hi, how do I solve this in Rails: Lets say I have a User and a Message. Now, a Message is sent from one User to another User, which means that in the Message I have to reference a User twice! This seems to be a problem, if I do not user one-to-many or many-to- many relationships, because it seems to me as if I could reference a Model of the same type only once. However, I would like the Message

Yep I tried those two options, and nothing... Even if the pre-user conf files have a log file in the same directory, which I touch before trying, messages keep going to syslog... I tried with 666 permissions on rsyncd.log too just to make sure... The following is one of the user's conf file, hope theres a clue. Thanks! log file = /home/pluto/rsyncd.log <<< This is the problem!!

Hi all, I am new to puppet, and I am trying to manage a windows agent using puppet. I wrote a manifest file which will copy a text file from puppet master (linux) to the puppet agent(windows). When I tried to run the puppet agent, I was getting the following error. err: /Stage[main]/Module1/File[change-ip.bat]: Failed to generate additional resources using ''eval_generate: Error

Hello all ! I have a model being validated that spits it''s error messages on the resulting page using: error_messages_for(:mymodel) .... Basic stuff. It''s working perfectly. Now, I have something else I want to check on the same page (that isn''t an attribute to the Model)... and am trying to add it using: @mymodel.errors.add_to_base("another error here")

I'm new in both R and statistics. I "did my homework", I tried the archives and whatever I managed to get from the sources, but still I need assistance with the plsr package. I have a model with 2 core determinants D1 and D2, made by 3 indicators each (D1a,D1b,D1c and so on). Also I have 2 moderating variables (m1,m2), where m1 moderates D1 and m2 modarates D2. The dependent

Hello! I am using package "VAR". I've fitted my model: mymodel<-VAR(mydata,myp,type="const") I can extract the Log Liklihood for THE WHOLE MODEL: logLik(mymodel) How could I calculate (other than manually) the corresponding Akaike Information Criterion (AIC)? I tried AIC - but it does not take mymodel: AIC(mymodel) # numeric(0) Thank you! -- Dimitri Liakhovitski

Greetings. I am running rsync 2.6.2 on both the server and the client. Server is Fedora Core 2 and client is Red Hat Linux 9. I am suffuring of the following errors on the server side: Jun 7 19:43:27 tux101 rsyncd[24906]: file has vanished: "redhat/9/en/os/i386/RedHat/RPMS/gtk2-engines-2.2.0-2.i386.rpm" (in module1) This messages repeats for a whole bunch of rpm files

Please, help me understand if 'use chroot' option in daemon config is secure enough. Rsync manual has following lines: As an additional safety feature, you can specify a dot-dir in the module's "path" to indicate the point where the chroot should occur.  This allows rsync to run in a chroot with a non-"/" path for the top of the transfer
