Polymorphic filter

[ravensnowbird]

I have a generic interaction that takes a object of any class and look at created_at updated_at and do some data manipulation return the some value. Currently my work around is sending a hash

{model_object: @car}
{model_object: @bus}

it would be nice to have the filter be able to use ActiveRecord::Object instead of Car Or say polymorphic: true.

You should be able to do this with object:

object :obj, class: ActiveRecord::Base

Or as an interface:

interface :obj, methods: %i[created_at updated_at]

For the cases when interface approach is too granular you can use extension that adds multiple classes support
