has_one and polymorphic association

[quolpr]

I have models:

class Car::Rim::Rim < ActiveRecord::Base
  belongs_to :param, polymorphic: true
end

class Car::Rim::EquipParam < ActiveRecord::Base
  has_one :rim, as: :param
end

class Car::Rim::CarParam < ActiveRecord::Base
  has_one :rim, as: :param
end

For Car::Rim::EquipParam or Car::Rim::CarParam selection form of rim does not appear. But if association will be "has_many" - all will be fine.

Has there been any movement on this? I have exactly the same issue and not sure how to resolve it

What if you configure:inverse_of ?
