Rails table-less model or a better way

I am using Rails 3.2.12.

I have a model A and table called a. I need to tag in a_details which is a set of attributes based on type of A. There is no table for a_details. Its made on the fly. In the show method I'm calling a method getAdetails and in the response I am passing both as JSON objects, A and A_details.

This gets tricky in the index method as there is going to be many and I don't think I want to loop through each one to make an array object and render them through. I was thinking about table-less model and using a gem called activerecord_association using the :include method while rendering to JSON. I was thinking, is there a better way of doing this?

# show method.
a = A.new
@a_detail = @a.getADetails
response = {:notification => @a.as_json(:include => :creator), :a_detail => @a_detail}

#index
 respond_to do |format|
  format.html # index.html.erb
  format.json { render json: @objects.as_json(:include => :creator) }
end

How about using the :methods option?

render json: @objects.as_json(include:'creator', methods:'getADetails')

From http://api.rubyonrails.org/classes/ActiveModel/Serializers/JSON.html#method-i-as_json

Edited to return an array
