Multiple models to be used for a single row

[mkhanal]

Our CSV's single row represents multiple models, which may or may not have an ActiveRelation amongst themselves. it would be awesome to have multiple models with columns mapping for each models.

I'd recommend creating a proxy object that responds to .transaction, .find_by and #save. :)

class AllTheThings
  def self.transaction
    ActiveRecord::Base.transaction do
      yield
    end
  end

  def self.find_by(attributes)
    # ...
  end

  def save
    # ...
    build_one_thing.save && build_the_other_thing
  end
end
