Using transaction in non-active record model

I want to use logical models to aggregate data to present information to the user. For example, I have a controller:

class OrdersController < ApplicationController   def

end

Sorry about above. The post should be:

I want to use logical models to aggregate data to present information to the user. For example, I might have a controller that looks like the following:

class OrdersController < ApplicationController   def new     @order = Order.new     @address = Address.new   end end

What I would prefer to have is:

class OrdersController < ApplicationController   def new     @logical_order = LogicalOrder.new   end end

Logical Order would look like (NOT and ActiveRecord model):

class LogicalOrder   def order      @order ||= Order.new   end

  def address     @address ||= Address.new   end

  def save      address_saved = address.save      order_saved = order.save     address_saved && order_saved   end end

I have simplified this. There is an initialize and method_missing method in order to hook it all up correctly.

My question is this. In this save method, it is not wrapped in a transaction block, like I would like. Since this model is not an active record model, how can I implement the save method such that it is wrapped in a transaction. I have thought about pushing the save logic back into one of the active record models (like the Order model), but I would prefer to do it within this class. Any thoughts?

Thanks,
