I''m using Windows and Postgres 8. I installed RMagic gem thingy and FileColumn plugin ok. I followed instructions exactly as directed on FileColumn web site which is very straight forward: ---model class My_model < ActiveRecord::Base file_column :column_for_file_name end -----view -upload form--set to mulitpart <%= file_column_field "my_model", "column_for_file_name" %> ---controller upload @my_model = My_model.new() @my_model.save(params[:my_model]) end I get...

...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 model :MyModel end The model''s file name is my_model.rb. If I rename the file to MyModel.rb it works, or if I change the line of code to model :my_model it works. I used the generator for the model so it seems that the file name should follow rails conventions. But it seems that the model method of ApplicationController is looking for a file name...

Hi all: I want to fit a multinomial logit model with VGAM package, however I cannot find a way to check the residuals since residuals(my_model) and resid(my_model) does not work. Any suggestions? Thanks in advance. Alex Brito [[alternative HTML version deleted]]

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 about, however, the UPDATE statement produced by update_attributes will still assign a value to this column. Even though its unlikely, if the separate process updates the record in the time betweent the find,...

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 ... end end Thanks, Steffen -- Posted via http://www.ruby-forum.com/.

Hi.

Hello, I generated a controller, using the command: ruby script/generate controller my_kontroller my_model The generated controller file, however, contains an empty class definition. The default controller code is missing. Any idea what went wrong? Thanks, gk -- Posted via http://www.ruby-forum.com/.

...), 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 my_models.parent_type = ?", a.id, a.class.base_class.name) Is there a philosophical reason it doesn''t make this transformation? - ff P.S.: After writing this, I realize it''s not just for polymorphism. I would expect the NON-po...

First of all, thanks for you time. I have kind of a tricky question and wanted to see what you guys thought. ------------------------------------------- Lets say I have this: ------------------------------------------- class Purchase < ActiveRecord::Base validates_numericality_of :some_number, :only_integer => true end ------------------------------------------- Then I do this:

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 observation 458" As I did not find any documentation or any discussion concerning this warning message, I looked in the klaR source code and found the following line in predict.NaiveBaye...

Does anyone know how to disable a model''s callbacks? I have a routine that increments a page_view counter for various model objects in an after_filter in my ApplicationController. I call this: increment_page_view() Rather that checking through the trace array in each model callback for "increment_page_view" I''d rather disable the callbacks from inside

...e display for a single attribute such that if the value is an integer, it displays with no decimal point (e.g. "1"), but if it is non-integer, it displays with a decimal point (e.g. "1.25"). 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 a better way altogether? thanks, Jeff -- Posted via http://www.ruby-forum.com/.

So, I have a plugin that adds a method to ActiveRecord::Base, let''s call the method is_encrypted. class MyModel < ActiveRecord::Base is_encrypted end So, my question is, how do I write a spec to show that is_encrypted is called here? I would rather not write specs that say that the behavior is there, since I have tested the behavior already in my plugin. Thanks. -Corey --
