This doesn't sound like a polymorphic relationship (at least not in terms of tables). Are living, shop, residential and commercial each models, or just attribute values for a building model (living or shop) and a block model (residential or commercial)? It feels like this is more just a case of a complex validation where you need to check the building type of a related building and the block_type of a related block according to the activity type. -- Posted via http://www.ruby-forum.com/. -- You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.
