Hi,
I'm currently having the situation where I have to implement a polymorphic has_and_belongs_to_many by introducing an in between model that handles all the "has_many :as" and "belongs_to :polymorphic" association implementations... and is not doing anything else. Thing I don't like it here is, I am unnecessarily loading AR instances only to execute SQL that leads me to whatever data I want to fetch. I would then gladly remove the models, keep the DB tables, and have is all work with some kind of has_and_belongs_to_many polymorphic magic. Something like: class Song < ActiveRecord::Base has_and_belongs_to_many :genres, :as => :taggableend class Genre < ActiveRecord::Base has_and_belongs_to_many :taggables, :polymorphic => trueend or similar, I haven't put much thought into that. I would like to hear some opinion of more experienced Rails developers to know if this would be a valuable feature. -- You received this message because you are subscribed to the Google Groups "Ruby on Rails: Core" group.
