Ruby on Rails

Could this be done with fields_for?

Say I have a Dog that has_may legs (In this case we don't care how many).  In the _form for Dog, I would like to assign a pre-existing let to him.  I would like to do something like this:

<%= f.collection_select :leg_1, Leg.select { |l| l.dog_id == nil }, :id, :description %>
<%= f.collection_select :leg_2, Leg.select { |l| l.dog_id == nil }, :id, :description %>

Then in my controller's create action:

@dog = Dog.new(params[:dog])
@dog.save
leg = Leg.find(params[:leg_1])
leg.dog = @dog
leg.save

The problem is that the collection_select is trying to set the leg_1 value as part of Dog, which of course does not exist. Do I need to create 'view model' for doing this?

Thanks,
