Hello! Im using ruby 1.9.2 and Rails 3.0.3.
I have the following models class Property < ActiveRecord::Base class Feature < ActiveRecord::Base class DefaultFeature < Feature class CustomFeature < Feature class PropertyFeature < ActiveRecord::Base One Property can have many Features, and one Feature is associated with many Properties (joined through PropertyFeature model). There are two kinds of Features: DefaultFeatures and CustomFeatures, for what Im using single table inheritance. Both kinds of Features have exactly the same fields, but i need to differentiate them in my application. What i want to achieve, if possible, is being able to access Features from a Property instance like this: a_property.features a_property.custom_features a_property.default_features And also add features to a property: a_property.custom_features << CustomFeature.new a_property.features << CustomFeature.new The closest solution i could think of is this one: http://pastie.org/1499280 The problem I'm having is that when i call a_property.custom_features it brings all features from the property: custom AND default ones. I've already tried making polymorphic the belongs_to :feature association in the PropertyFeature model, but it raised an ActiveRecord::HasManyThroughAssociationPolymorphicError exception, so i assume rails is not supposed to work like that. I'd appreciate any help on how to do this (i've tried everything i could think of). Maybe my approach is wrong to begin with, in which case i'd love to hear a better way to to this. thanks! -- rodrei -- You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.
