I love the query interface (ActiveMethod::QueryMethods), but one thing
has bugged me: why doesn’t it generate calls for polymorphic
associations? For example:
class MyModel < ActiveRecord::Base
belongs_to :parent, :polymorphic => true
end
I would expect:
MyModel.where(:parent => a)
to be equivalent to:
MyModel.where(“my_models.parent_id = ? AND my_models.parent_type = ?”,
a.id, a.class.base_class.name)
Is there a philosophical reason it doesn’t make this transformation?

P.S.: After writing this, I realize it’s not just for polymorphism. I
would expect the NON-polymorphic case to transform:
MyModel.where(:parent => a)
into
MyModel.where(“my_models.parent_id = ?”, a.id)
