I remember reading something awhile back about an easy way to work with object arrays in views. Say I want to arrange 20 images objects in rows of 3. I have a collection of @users, where each user has a user.thumbnail_url image. Is there some way to split these up so that they can be easily parsed in rows of three?

I''m using Windows and Postgres 8. I installed RMagic gem thingy and FileColumn plugin ok.

Hi, I was trying to draw some ROC curves (prediction of case/control status), but seem to be getting a somewhat jagged plot. Can I do something that would 'smooth' it somewhat? Most roc curves seem to have many incremental changes (in x and y directions), but my plot only has 4 or 5 steps even though there are 22 data points. Should I be doing something differently? How can I provide a

One of my models has a column that is updated very frequently from a separate process, so it is important that when a record is saved in rails, this column should be left alone. In the update method of the controller I have: @record = MyModel.find(params[:id]) @record.update_attributes(params[:my_model]) params[:my_model] doesn''t have a reference to the column I''m talking

Hi, I have problem accessing the testfixture. The values from the YML-Fixture-File are correctly written into database, but accessing the fixture is impossible. It is always nil. Is anything wrong with this test? class MyModelTest < Test::Unit::TestCase fixtures :my_model def test_simple a = MyModel.find(@my_model["first"].id) # Accessing @my_model is impossible ...

Hi, I run R 2.10.1 under ubuntu 10.04 LTS (Lucid Lynx) and klaR version 0.6-4. I compute a model over a 2 classes dataset (composed of 700 examples). To that aim, I use the function NaiveBayes provided in the package klaR. When I then use the prediction function : predict(my_model, new_data). I get the following warning : "In FUN(1:747[[747L]], ...) : Numerical 0 probability with

The easiest way to do this seems to be if I could override the to_string method for my_model.my_attribute.to_s. Is there a way to do this? Or
