I''m spidering historical weather data from various sources. I have a WeatherStation class that is begging for an STI implementation: a WeatherStation is associated with a specific weather service, and each weather service has its own protocol for fetching weather data, but most of the code is can be shared in the WeatherStation parent class. Ergo STI. But there are a lot of weather

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

I have a STI class tree. I want to set some default values (calculated values so I can''t set it in the database as defaults) on every created instance regardless of what subclass is actually instantiated. So I figured adding a after_create callback in the top class in the hierarchy should do the trick. It seems it doesn''t get called :( Code: class SuperClass <

Guys, I have a relationship between model classes that I believe is best represented by inheritance, but the likelihood that things will change often is driving us to composition instead. So, I have a class called Autos, and subclasses called Suvs, Minis, Mids, Sports, for example. We have been requested to avoid the STI approach to this, because of fear of a quickly growing table with

Folks, I''m fairly new to Rails, and I''ve Googled around for an answer to this question with no luck... Consider a little blog application that has uses single-table inheritance for the handful of different content types via a Content base class and subclasses like FooContent and BarContent. That part all works well for me. Now consider the view that presents actions to the

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

Hey gang, How does STI work with HABTM? For instance...let''s say I have the following models ----- Category < ActiveRecord::Base Item < ActiveRecord::Base Product < Item Deal < Item ----- Each product or deal can have categories. Would I then setup Item with has_and_belongs_to_many :categories, then create a table categories_items ??? Is there a better way to do it?

I''m trying to understand how to do the following, but am finding myself stuck. I have three main tables; here are the first two: CREATE TABLE reference_items ( "id" integer primary key, "type" varchar(20), "title" varchar(255), "year" year(4) ); CREATE TABLE "agents" ( "id" integer primary key, "type"

All outputs have a 1:1 relationship between connectors and encoders and the driver is relying on the atomic helpers: we can drop the custom ->best_encoder() implementations and let the core call drm_atomic_helper_best_encoder() for us.

OK. Here''s another one on STI (thanks for the help of all of you with my previous STI question, and I promise to update the wiki with the info). I''m having a prob with validation with the sub-classes. It''s a bit long-winded to explain, but I''ll post all the logs and code if there''s no obvious answers. Basically, however, I have validation on the

All, I had been working on a project that was using STI to a very high degree. It also was using a HABTM table that had a couple extra attributes. It seems that with 1.1 push_with_attributes is deprecated and I am having a bit of trouble moving things to using has_many :through The original schema I had worked like this : create_table "nodes" do |t| t.column "title",
