Given a standard has_many relationship between two objects. For a simple example, let's go with:

class Order < ActiveRecord::Base
  has_many :line_items
end

class LineItem < ActiveRecord::Base
  belongs_to :order
end

What I'd like to do is generate a stubbed order with a list of stubbed line items.

FactoryGirl.define do
  factory :line_item do
    name 'An Item'
    quantity 1
  end
end

FactoryGirl.define do
  factory :order do
    ignore do
      line_items_count 1
    end

    after(:stub) do |order, evaluator|
      order.line_items = build_stubbed_list(:line_item, evaluator.line_items_count, :order => order)
    end
  end
end

The above code does not work because Rails wants to call save on the order when line_items is assigned and FactoryGirl raises an exception: RuntimeError: stubbed models are not allowed to access the database

So how do you (or is it possible) to generate an stubbed object where it's has_may collection is also stubbed?
