Hi, [This is a repost, I can?t find where went my previous post, ] I wanted to create subdirectories in the fixtures directory in order to be able to manage many different initial states for my system (or to sort fixtures / corresponding model subpackages). I came up with the idea of writing: Test::Unit::TestCase.fixture_path = RAILS_ROOT + "/test/fixtures/selling"

Dear all, I would like to draw three forest plots to represent results at years 1, 2 and 3. I have the data as point estimates and 95% confidence intervals. Using the following code I can get three basic forest plots - the first which has the table of results. I have to plot each separately as the usual par(mfrow=c(3,1)) does not work with the function forestplot within rmeta. I can easily put

Hi I have an asterisk box with digium hardware connected to a Siemens EWSD version 15 using a crossed E1 cable. The asterisk is serving as a h323 media gateway. When i start asterisk, the Siemens gives me this alarm: REPORTES GENERADOS EN LA EWSD AES/V15SBOL/BOLCBK1V51327079/013 05-06-06 11:25:38 7773 3062/03728 HF.ARCHIVE-80040

I am not sure if this is a bug in ActiveRecord or is this the intended behavior. If it is then it does not make sense to me. In a nutshell: If you change an aggregate object attribute created via composed_of method (see Agile Web Development - Second Edition Chapter 17 page 313 onwards) and then save the model, the change to the model (composite attribute specifically) will not be saved UNLESS

Hi Everyone, I have data in a long format e.g. there is one row per patient but each follow-up appointment is included in the row. So, a snippet of the data looks like this: TrialNo Drug Sex Rand Adate1 Date1 Dose1 Time1 Adate2 Date2 Dose2 Time2 B1001029 LTG M 15719 30/04/2003 15825 150 106 29/08/2003 15946 200 227 B1117003 LTG M 15734 30/04/2003 15825 200 91 03/09/2003 15951 250 217

Hi, How do I relate a table to another when one of the models uses single table inheritance? Will this even work? This is the specific problem I am having: There''s an "Address" model with "ShippingAddress" and "BillingAddress" as subclasses. It looks like this: class Address < ActiveRecord::Base End class ShippingAddress < Address has_one :order

Hi, I have a simple program that tries to do something really basic. First, I have a company Model : ------------------------------------- class Company < ActiveRecord::Base has_one :billingAddress, :foreign_key=>"id", :class_name=>"Address" end Then I have the address Model : -------------------------------------- class Address< ActiveRecord::Base belongs_to

I''ve been searching the web, wikis, and more, and I haven''t turned up examples of how to have multiple entities in a single-table inheritance related to anything. I have an addresses table, but multiple entities can have Addresses: both Person (which has 2 addresses) and Retailer. I''ve been told that I need to use single-table inheritance, and this was my attempt:

I am attempting to use the lars package with a sparse input feature matrix, but the following fails: library(Matrix) library(lars) data(diabetes) attach(diabetes) x = as(as.matrix(as.data.frame(x)), 'dgCMatrix') lars(x, y, intercept = FALSE) Error in scale.default(x, FALSE, normx) : > > length of 'scale' must equal the number of columns of 'x' > > More

I may be totally wrong about what the fields_for method is supposed to do, but for some reason I thought using it scoped an object around an association. For example, I have a User class and when you''re creating a new user I want to use fields_for to add a BillingAddress to the user like so: <%- fields_for :billing_address do |billing_address_form| -%> <%= render :partial

Dear All, I am currently working with the coxph function within the package survival. I have the model h_ij = h_0(t) exp(b1x1 + b2x2) where the indicator variables are as follows: x1 x2 VPS 0 0 LTG 1 0 TPM 0 1 [[alternative HTML version deleted]]

I have my Model<ActiveRecord::Base , but whenever I try something like Model.calculate() or Model.maximum ... I get NoMethodErrors. Why can I use any of the other ActiveRecord methods, but none from Calculations and what do I do to remedy this? thanks -- Posted via http://www.ruby-forum.com/.

Maybe there is an obvious answer and I''m being dumb, but why does activerecord allow me to call it''s private methods? >> i = Item.find(33) => #<Item:0x2360080 @attributes={ ... output removed >> i.price = ''25'' => "25" >> i.update => 1 >> i.create_or_update => 0 >> i.price = ''26'' =>

I need to turn off and on the autocommit in MySql is there a method in active records that allows me to do this? or is there a method which allows me to type in the pure mysql code "set autocommit=0" Thanks. -- Posted via http://www.ruby-forum.com/.

The new version of cached_model features bug fixes and tests! Bugs fixed: Updating a model no longer stores associations into the cache. This could cause strange, hard-to-debug bugs when an invalid set of assocations was retrieved along with a cached model. Reloading a model refreshes the cache. When CachedModel::find can''t understand query params and a single result is
