similar to: STI functionality, but then with multiple tables

With the help of the Rails Recipes have got a self-referential HABTM relationship working, but I''m really struggling with getting a new entry from a form accepted. i should say here that the form is also submitting info for the join table too. So in my model I have: class Type < ActiveRecord::Base has_and_belongs_to_many :subtypes, :class_name => ''Type'',

Hi all, This is perhaps more a statistics question than an R question, but I hope it's OK anyhow. I have some data (see below) with the number of tests positive to subtype H1 of a virus, the number of tests postive to subtype H3, and the total number of tests. This is for two different groups, and the two subtypes are mutually exclusive. What is the best way to test if the proportion of H1

I got the following: > library(foreign) > swal = read.spss("swallowing.sav", to.data.frame =TRUE) Warning message: In read.spss("swallowing.sav", to.data.frame = TRUE) : swallowing.sav: Unrecognized record type 7, subtype 21 encountered in system file > The bulk of the data seems to read in a usable form, but I'm curious about what might be getting lost

Struggling a little with getting the syntax right for a STI model. Prob just being a bit dense. Couple of questions I''m hoping you guys can answer: Assume here I''ve got: class Person class Manager < Person class Slave < Person 1) How does person[:type] differ from person.type when type is the column used to specify the subclass. They seem to output the same

Hello, I wanted to know about the reasons Apple dropped the support for "arm" target in its ld64. After searching in the sourcecode I found out that ld64 supports armv4 armv5 armv6 armv7 and its subtypes. The code shows that -force_cpusubtype_ALL for ARM targets is no more supported in "src/ld/options.cpp") and static const ARMSubType ARMSubTypes[] doesn't include

First, BRAVO for this wonderful plugin: has_many_polymorphs ! Now my problem: 4 models : Collection, Page, Fragment, Belonging (which is the join table): 1 class Collection < ActiveRecord::Base 2 has_many_polymorphs :elements, 3 :through => :belongings, 4 :from => [:pages, :fragments, :collections], 5 :as => :collector, 6 :parent_order =>

Hey folks I have a bunch of classes that are polymorphs, with has_many_polymorphs (they are all ''labellable'', which is similar to being ''taggable'' in the acts_as_taggable scheme). I have a couple of modules, LabellableInstanceMethods and LabellableClassMethods in a file called labellable_methods.rb. The classes all get labelled with

No matter what I try I''ve been unable to work how to get this to work with the cool ActiveRecord helpers. I''m not sure if it''s possible, Josh Susser''s blog suggests it is, but damned if I can work it out... I have: Container which can contain one or more Element. An Element is a polymorph of either a Container or a Chunk. An Element can exist in one or more

I have done a little polymorphic associations stuff and have refreshed my memory on it again. What it seems like is that if I have a particular record and I want to make it easy for many different parent records to associate with it using has_one or has_many, that is fine. If I want a parent record to have multiple kinds of children through one association, I don''t see how to do that

Hello, I installed Icecast 2.4.3 by downloading http://downloads.xiph.org/releases/icecast/icecast-2.4.3.tar.gz CentOS 7 Then ./configure make make install Its working. My only issue : I have 3 streams, I see the name of my station 3 times in Icecast directory. I tryed to hide 2 streams by using the hidden and public tags and force showing the total of audiance in the one public stream. i

Parametric polymorphism is different from subtype polymorphism; you can have one without the other. Parametric polymorphism just means that you can use type variables (like T) in the IR, which are later instantiated to

I was working with acts_as_taggable earlier and thought I could make it a bit friendlier. I submitted a ticket and patch #8279. Basically, there are three differences. 1. Fixed the deprecated :dependent => true 2. Added migration generator (it has really specific requirements on table layout, so might as well generate it). 3. Expanded the README to explain using the migration and to include

Hi, lets say I have a a table, "Linkings" that I am using for polymorphic associations. One of the associations is to the "person" table, and there are several other associations. "Person" has 2 types, "slacker" and "suckup". It is modelled as such: class Linking < ActiveRecord::Base belongs_to :person belongs_to :linkable, :polymorphic

Hello, I have a couple of doubts, as listed below: 1. To list all the global variables in the module, I am iterating using type_iterator and for each Type I get, I am using value_iterator to iterate over Values . In the second iteration I am getting unexpected results. For each type obtained from type_iterator->second, value_iterator->first produces the same list as what

I am having trouble with an many to many polymorphic association with STI involved. The problem is described clearly in the following StackOverflow question, so I will leave this thread short: http://stackoverflow.com/questions/6582074/activerecord-has-many-through-polymorphic-associations-with-sti I am posting here hoping to get advice/direction/a solution for this, as I''ve so far been

If I define an association (in my case a polymorphic one) in an STI parent class, and try to eagerly load it in a subclass, I get the following error: ActiveRecord::ConfigurationError: Association name ''myassoc'' was not found; perhaps you misspelled it? If I redefine the same association again in the STI subclass, it works. Is this a bug or what? -- You received this message

I''m stumped on how to get past this. It''s Rails 2.0.2. I have a class, Show. Using STI, I''m using that as a base class, and have DayShow and NightShow that inherit from it. ### class Show < ActiveRecord::Base end class DayShow < Show end ### In my shows/edit.html.erb, I have: <% form_for(@show) do |f| %> However, when I use it with a @show that has

I have a MasterEvent model. It has attributes that is required by another model Event. The user selects the MasterEvent model and I create the Event model by merging the attributes of the selected MasterEvent with the attributes that were presented for the Event model in the form. I have association declarations in the MasterEvent and Event models. If I use STI does the subclasses inherit the
