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`:

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 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

Hi, I am attempting to replace an exiting photo with a new one uploaded by the user. I am using attachment_fu and I am coming up with the following exception: can''t convert nil into String /vendor/plugins/attachment_fu/lib/technoweenie/attachment_fu/backends/file_system_backend.rb:23:in `join''

I have a couple models that inherit from a base class that then inherits from AR. When they are used in a polymorphic relationship the "type" is always the base class. Just curious if anyone has a reason why it doesn''t use the *actual* class rather then the base_class. I have patched AR to use the actual class if !base_class.table_exists? but it adds another query each time

There's still room for additional refactoring as we may want to eventually split out nic, bonding, and ip address manipulation into their own controller/svc module, but that would be a much more extensive redesign than we want to deal with for the overall service layer creation refactoring.

Running into an interesting problem that at first glance appears to be a bug in the AR association code. However, it''s explicitly coded this way so I''m not so sure. I have some code like this: class Address < ActiveRecord::Base belongs_to :addressable, :polymorphic => true end class Person < ActiveRecord::Base has_many :addresses, :as => :addressable,

Hello, I have a dual boot with Windows 7 64 bit enterprise edition and Opensolaris build 134. This is on Sun Ultra 40 M1 workstation. Three hard drives, 2 in ZFS mirror, 1 is shared with Windows. Last 2 days I was working in Windows. I didn''t touch the hard drives in any way except I once opened Disk Management to figure out why a external USB hard drive is not being listed.

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 ...

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 a problem when sending parameters from link_to_remote. My link code: <%= link_to_remote "Remove", :url => object_relation_path( :id => 0, :object_relation => { :parent_id => @product.id, :parent_type => "Product", :child_id => content_object.id, :child_type => "ContentObject",

Hi all I have the following plugin code: module IncenseCrud def self.included(base_class) base_class.extend(ClassMethods) end module ClassMethods def performs_incense_crud def index list return render(:action => ''list'') end end end end In init.rb I have the following: require File.dirname(__FILE__) +

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 =>

As great as Rails 2.1 is, I for the life of me cannot figure out why polymorphic associations do not support reconfiguring the type column used. For example, I have no way to do a polymorphic association using a lookup hash which maps an integer to a class name. Storing a TINYINT unsigned is waaaaay more efficient than storing a string like "SomeActiveRecordModel" over and over again.

Dear list, I made a logistic regression model (MyModel) using lrm and penalization by pentrace for data of 104 patients, which consists of 5 explanatory variables and one binary outcome (poor/good). Then, I found bootcov and robcov function in rms package for calculation of confidence range of coefficients and odds ratio by bootstrap covariance matrix and Huber-White sandwich method,

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 --

Hi, I have an application that uses single table inheritance. Very simple stuff: class Place < ActiveRecord::Base class City < Place lets say I have a City on the @place whenever I try using the render @place I will get an error, saying the templace cities/city doesn''t exist but I do have a places/place template. Is the any nice way to add this fallback for the base_class

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
