similar to: Model names in controllers

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

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

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 --

Hey, I have the following line in my controller: User.create(:email => "fuuu-+RB1Aph5k6s@public.gmane.org", :password => ''asldfkjadsfadsf'', :ip => request.remote_ip) my IP is 127.0.0.1 - now User.find_by_ip(''127.0.0.1'') returns 0 records although User.first contains ''127.0.0.1'' if I change it to: User.create(:email =>

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 ...

I am assuming this an appropriate place to discuss this, but if it isn''t my apologies- just let me know. Just a Rails 4-ish thing. Am attempting to pull AMS (active_model_serializers), strong_parameters, and the "permitter" strategy that Adam Hawkins is using: http://broadcastingadam.com/2012/07/parameter_authorization_in_rails_apis/ Code so far is here (in the

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",

I just posted this ticket in Lighthouse, but thought perhaps some discussion here would help point me in the right direction toward a solution. Here is a description of the problem (from the ticket - https://rails.lighthouseapp.com/projects/8994-ruby-on-rails/tickets/6693-arel-union-does-not-support-order-or-limit) : > If we take two `ActiveRecord::Relations` and join them via `union`:

Hello everyone, just wondering if anyone can help me with a migrations question here. Using: rails 2.0.2 ruby 1.8.6 (2007-09-24 patchlevel 111) [i386-mswin] mysql 5.0.45 Platform: windows xp The problem: ---------- I created a migration that is designed to add a column named "deleted_at" (timestamp) and then remove a column named "is_deleted" (boolean). The idea is to

Hi! If I have a method that is useful in both models and in views, where would be the appropriate place to put it? The method in question just takes two dates as strings, tries to parse them and returns all dates in the range between them. It also takes care of the issues when the dates are badly formatted etc etc.. This method is being used in several models (so a simple class method in

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:

I was looking at Kyle Mawell''s extremely nifty-looking StateModels plugin http://www.kylemaxwell.com/articles/2006/02/06/fun-with-single-table-inheritance and before I go down the road with it, I was wondering if anyone has used it with file_column. The way file_column deals with an uploaded file -- by storing it to the filesystem in a path that employs the model name and id --

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]]

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

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

Hi everyone, Can someone please help me in these questions?: 1)if I use crossvalidation with svm, do I have to use this equation to calculate RMSE?: mymodel <- svm(myformula,data=mydata,cross=10) sqrt(mean(mymodel$MSE)) But if I don’t use crossvalidation, I have to use the following to calculate RMSE: mymodel <- svm(myformula,data=mydata) mytest

I have dose response data analyzed with the package 'drc'. 'summary(mymodel)' prints my kinetic parameters. I want that text in an ASCII text file. I want to get exactly what I would get if I copied and pasted from the terminal window. I've read the documentation on data export to text files here:

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

Hello again, I guess this is more of a Ruby question, but here goes anyways... I want to intercept all calls to non existent class methods and then call an existing class method with the non existent name. In code... class MyModel < ActiveRecord::Base def MyModel.method_missing(symbol, *args) MyModel.func(symbol.id2name) end def MyModel.func(func_called) puts "You
