polymorphic relational associations (using has_many_related)

[Josef Richter]

Hi,

I have Suggestion, Feature and Vote models.
suggestion embeds_many features
suggestion has_many_related votes
feature has_many_related votes

I am trying to make those has_many_related associations polymorphic.
but I had no luck using options like :polymorphic => true and
has_many_related :votes, :as => :votable

here is the gist with relevant code http://gist.github.com/454061

as you can see, for the time being I used belongs_to twice in Vote
model, which puts suggestion_id and feature_id fields into each vote,
where I use only one of them. I also have a conditional statement in
votes_controller which recognizes whether I am casting vote on
suggestion or feature.

but this is obviously not true polymorphism. could you please give me
some hints what am I doing wrong and what is the right way, please?

Thanks very much

Josef

does anyone know what the state of polymorpic associations is? the
documentation says it's there only for embedded docs.
